It started more than 20 years ago as research project and is now used by thousands of customers. IBM continues to enhance Spectrum Scale\, in response to recent hardware advancements and evolving workloads.\nThis presentation will discuss selected improvements in Spectrum V5\, focusing on improvements for inode management\, vCPU scaling and considerations for NUMA. \nPart 1 (inode management):\n \n \n \n \n \n \n \n \n \n \nPart 2 (vCPU scaling and NUMA considerations):\n \n \n \n \n \n \n \n \n \n \n \nDownload slides here \nQ&A – inode management\nQ: If I make the block size 8k\, can an inode stuff a file of that size­?\nA: ­No \, the max inode size is 4K. As discussed on the call\, changing the blocksize (including the metadata blocksize) doesn’t impact the size of an inode\, which is currently limited to 4K. \nQ: ­When files are created an inode number is assigned from 1-Max. 32bit applications can only address inodes up to 4b. With millions of temp files created during application runs\, inodes get used up very quickly.  But once the job is finished the files are­ ­deleted\, but the inodes are not recycled. ­This results in filling the inodes while the file system isn’t full. Can inodes/files that have been deleted\, have their inode recycled for future use?\nA: Inodes do get reused after deletion. How many independent filesets do you have? If you only had the root fileset and you set the maxInodes to less than 4b\, then you can never have an inode number greater than 4b. \nQ: ­Do we have any idea how long it takes to re-layout the inode allocation map?  And can that be done while the FS is mounted?\nA: The run-time for this operation will depend on the size of the existing inode allocation map file since we will be migrating data from the exiting map to the new map. In one customer engagement\, the migration completed in an hour and in another case it took 18 hours.\nWhile this operation can theoretically be done while fs is mounted\, we have currently restricted it to be done with file system offline for safety reasons. We are evaluating to make this operation online in a future release. The re-layout parameters can however be tested with file system mounted. \nQ: ­Are there counters that report the lock collisions/waiters for lock contention that would indicate whether a re-layout is desirable?\nA: ‘mmfsadm dump ialloc’ provides counters on segment search. Grep for ‘inodes allocated from’. Ideally\, we expect allocations to happen from ‘inodes allocated from list of prefetched/deleted inodes’ or ‘inodes allocated from current ialloc segment’. Also\, long waiters during file creation is indication of inode space pressure. \nQ: Why does a large number of NumNodes influence mmdf run time?  (seen some minutes) ­\nA: mmdf fetches cached data. This should not be impacted by cluster size. \nQ: How does NumNodes relate to the number of segments?\nA: The number of inode allocation map segments are chosen such that every node can find a segment with free inodes even if 75% of all segments are full. This has to do with the inode expansion getting triggered only when the inode space is 75% full. We want inode allocation to continue while the inode expansion is taking place. This means that the number of segments would be roughly 4 times NumNodes. \nQ: Are there any general recommendations for initial inode allocation?  I know this depends on the filesystem’s expected use. We typically just base it roughly off existing systems.\nA: Use the default value of allocated inodes (by omitting NumInodesToPreallocate argument of –inode-limit option of mmcrfs/mmcrfileset) when creating file system/independent fileset and let the inodes expand on demand.­ \nQ:  How is the inode allocation map\, and its segmentation\, affected if metadata NSDs are added or deleted?\nA: The inode allocation map is not affected by newly added NSDs as it only tracks inode state. The block allocation map is the one that tracks free/used disk blocks and will get updated on new disk add/delete. \n­Q: Can we shrink the inode space\, if we by mistake allocate a large inode space using –inode-limit?\n ­A: No. \nQ: ­When files are deleted\, does the recovery of free inode happen in lazy way? One customer has just reported that after deleting data from 5TB filesystem\, free space is not reflecting on the filesystem­.\nA: Yes. The files are deleted asynchronously in the background. You can run ‘mmfsadm dump deferreddeletions’ to see the number of inodes that are queued for deletion in mounted file systems. \nQ: At what version is automatic inode expansion available?\nA: Since the earliest spectrum scale versions. \nQ: ­How do you indentify the metanode?­\nA: ­Here is an example:\nls -i testfile\n68608 testfile \nThen find this inode number in ‘mmfsadm dump files’. (note that the mmfsadm dump command should be avoided in production)\n===== dump files =====\n[… search on inode]\n  inode 68608 snap 0 USERFILE nlink 1 genNum 0x49DE6F0F mode­‑ \nThe above is an example of how you might lookup the metanode for a file. \nYou can map the cluster name by looking at the ‘tscomm’ section of a dump\, e.g.:\n===== dump tscomm =====\n[…]\nDomain \, myAddr (was: )[…]\nUID domain 0x1800DF65038 (0xFFFFB6768DF65038)  Name “c202f06fs04a-ib1.gpfs.net”­ \nQ: Is metanode transient?\nA: ­ A metanode is a per file assignment. It lasts for as long as there are open instances of the file. The assignment is dynamic and the metanode role may automatically migrate to other nodes for better performance. \nQ: ­If some of the node went down and if metanode unable to get update from those failed nodes: In such situation how updates are maintained by the metanode­?\nA: A non-metanode will sends its updates to the metanode before it writes any dependent blocks to disk. If the non-metanode went down before it could send its updates\, then log recovery will ensure that there are no inconsistent modifications to disk data by the non-metanode. Spectrum Scale only guarantees persistence of data/metadata from the last sync window. \nQ: Can we limit metanode to migrate to remote node? Also\, will it help in improving performance if limit metanode in storage cluster?\nA: Metanode performance depends on how many nodes are sending metanode updates and how expensive the network send is. The file system uses such heuristics to determine the optimal metanode placement. In most cases it is best to let the file system make this decision. The only known use case for preventing metanode migration to remote node is if the remote node is in a compute cluster which cannot afford the overhead of a metanode operation. For this rare case we have an undocumented configuration parameter to force the metanode to be in the storage cluster. \nQ: Sometime when we delete large data\, it takes significant time to show free space in df -h command output. Do we need to run mmrestripfs to reclaim the deleted space faster?\nA: ­ ‘df -h’ would return cached information on free space. It is likely that the large file that was deleted has not freed up its space as file deletes happen in the background. You can use ‘mmfsadm dump deferreddeletions’ to get a count of number of inodes that are queued for background deletion. If the node is not overloaded on I/O and you find that the number of to-be-deleted inodes are not reducing at a reasonable rate (depending on the file size and I/O througput of the node)\, then we would need to investigate further by collecting dumps and traces. Please open a ticket with IBM support in such a case. The mmrestripefs command is for restoring/rebalancing data and metadata replicas. It would not have any impact on speeding up background file deletion. \nQ&A – vCPU scaling and NUMA considerations\nQ: We see in the mmfs log now following messages\, what does it mean? What is missing?\n­[W] NUMA BIOS/platform support for NUMA is disabled or not available. NUMA results are approximated and GPFS NUMA awareness may suffer.\nA: That means libnuma was found but numa_available() returned false. This is a platform firmware functionality shortcoming. Spectrum Scale can still get a lot of information as some is derivable from /proc . File a ticket with your server vendor that libnuma :: numa_available() returns false . \nQ: ­So\, any recommendations on POWER9 for SMT settings?  AIX versus Linux on Power?  We used to suggest smaller SMT modes in the past.\nA: We are running SMT-4 on some large POWER9 systems. Evaluate based on I/O vs workload needs as discussed verbally. \nQ: Are there any special NUMA considerations for AMD systems which are different to NUMA considerations for Intel systems?\nA: This is highly dependent upon the processor and chip set independent of brand and based on what that processor and chipset offer for tuning. We do not have any prescriptive guidance. \nUser group host: Simon Thompson\nSpeakers:\n\n\n\n\n Speaker NamePhotoBio\n\n\n\n\n Michael HarrisMike is a Senior Software Engineer on the Spectrum Scale Core Team.

CSI is a standard for exposing arbitrary block and file storage systems to containerized workloads on container orchestration systems like Kubernetes and OpenShift. Spectrum Scale CSI provides your containers fast access to files stored in Spectrum Scale with capabilities such as dynamic provisioning of volumes and read-write-many access. \n \n \n \n \n \n \n \n \n \n \n  \n \nDownload slides here \nEpisode 2:  Best Practices for building a stretched cluster \nQ&A\nQ: ­This slide (titled Spectrum Scale CSI Driver – Architecture) shows CPU architecture is x86­\nA: ­Yes\, with Spectrum Scale CSI Driver 2.0.0 only x86 is supported. The support for other architectures (IBM Power and IBM Z) will be provided in upcoming releases­ (IBM usual roadmap disclaimers apply). \nQ: ­Is the management of storage class available via Ansible?­\nA: ­Setting up a storage class is a one-time operation. While it might be done using Ansible (and Kubernetes integration modules)\, clients usually do the management using the Kubernetes or Openshift CLI or GUI.­ \nQ: ­Will the slides be provided post this presentation?\nA: ­Yes. You will find the chart decks\, recordings\, Q&A and related information for all past talks including this one at https://www.spectrumscaleug.org/experttalks/. \nQ:  Once you have CSI driver support for non x86_64 platforms\, will the Spectrum Scale cluster be able to be heterogeneous (AIX\, Linux\, x86_64 and ppc64le)? Will this cluster support AIX NSD only nodes?­\nA: ­ In the first release for non x86_64 platforms\, all worker nodes that have Spectrum Scale client installed need to  be of same CPU architecture and the same operating system. If there are AIX NSD nodes\, those must be outside of Kubernetes cluster.­ AIX NSD only nodes might be integrated by remote mounting the storage cluster to a client Spectrum Scale cluster that runs the Kubernetes workload. \nQ: ­Is Network Load Balancer a per-requisite must have for the CSI deployment?­\nA: ­No it isn’t.­ \nQ: ­ Is there a possibility to have Spectrum Scale clients installed within containers?\n ­A: ­We are working on a capability called Container Native Spectrum Scale (CNSS) where Spectrum Scale will run inside a container.  The initial release is planned for December 2020.  (Disclaimer: All dates are subject to change; IBM usual roadmap disclaimers apply)­ \nQ: Do we need to have an x86 “only” Spectrum Scale/OpenShift cluster and a ppc64le “only” Spectrum Scale/OpenShift cluster?\nA: ­The requirement of same CPU architecture and same operating system is only for Spectrum Scale Client node which are part of Kubernetes/ Openshift cluster. NSD server can be of other platform (as per Spectrum Scale support matrix at https://www.ibm.com/support/knowledgecenter/STXKQY/gpfsclustersfaq.html) \nQ: ­ Any plans for ability to self-provision Spectrum Scale clusters with containers?­\nA: ­Container Native Spectrum Scale (CNSS) will have an Operator that will deploy and configure a Spectrum Scale cluster automatically.  It will also remote mount the filesystem from a Spectrum Scale Storage Cluster. \nQ: ­One of the issues that we are trying to solve is to isolate Spectrum Scale IO with respect to each tenant/application/user on a single server just like how we can isolate cpu/network with cgroups. Would spectrum scale on containers help us in isolating or qos with storage IO?­\nA: ­Running Spectrum Scale in a container or CSI by itself will not address QoS.  A new fileset based QoS capability\, with CSI\, will be able to handle this in a future release­. (Disclaimer: All dates are subject to change; IBM usual roadmap disclaimers apply) \nQ: ­Does OpenStack have to be managed via the web gui. Can it be controlled via a CLI?­\nA: ­You are free to use either CLI or GUI.­­­ \nUser group host: Bill Anderson\nSpeakers:\n\n\n\n\n Speaker NamePhotoBio\n\n\n\n\n Smita RautSmita Raut is a Senior Software Engineer with IBM Storage Labs in Pune\, India.

It highlights the underlying architecture and how policies are executed in a IBM Spectrum Scale cluster. This episode also discusses example rules and policies facilitating Information Lifecycle Management accompanied with practical tips. \n \n \n \n \n \n \n \n \n \n \n  \nDownload slides here \nReferences\n\nWhitepaper: IBM Spectrum Scale ILM and Archiving Policies – A practical Guide\nSpectrum Scale ILM policy examples and scripts\nApache Tika\n\nQ&A\nQ: ­Which type of nodes participate in policy execution?\nA: Depends on the nodes specified with the -N option of the mmapplypolicy command. If the -N option is not specified\, then the command runs parallel instances of the policy code on the nodes that are specified by the defaultHelperNodes attribute of the mmchconfig command. If -N is specified then the command runs parallel instances on the nodes or node class specified with the -N option. For more information see the IBM Spectrum Scale knowledge center: https://www.ibm.com/support/knowledgecenter/STXKQY_5.0.5/com.ibm.spectrum.scale.v5r05.doc/bl1adm_mmapplypolicy.htm \nQ: ­Can I somehow identify the type of a file via the policy engine\, e.g. via the magicbyte? Or do I have to rely on the file extension?­\nA: The policy engine does not allow access to the data – only the file’s metadata including extended attributes­ can be evaluated by the policy engine. To identify the type of a file with the policy engine an EXTERNAL LIST rule can be used along with an external script that determines the type of files. \nQ: ­Will the external tool process the filelist in parallel on all nodes\, which are used to generate the filelist?\nA: Yes\, if an external tool or interface script is defined in an EXTERNAL POOL rule then this script is executed on all nodes that are specified with the -N option of the mmapplypolicy command. This assumes that all node specified with the -N option have access to the interface script. If this is not the case\, then the policy run fails. You can control the number of instances of the external tool pool with the option -m and the number of files passed to one instance of the external pool with the option -B of the mmapplypolicy command. \nQ: Are they any limitations or recommendations around length of rules in policy files? For example\, we have ~750 filesets we want to place data on a specific pool. Should we just have one rule\, or many rules for this?\nA: Placement policies will be stored in a single file. The challenge is not so much the length of the file but the number of placement rules contained in the policy files. Whenever a file is created the policy engine must walk through all rules to find a match. If there are many rules\, this will delay the file creation. Therefore I recommend to keep the number of placement rules low. For example\, you could organize the placement policies by storage pools. There is a limit of eight storage pools\, thus this would lead to maximal eight placement rules. In each rule you can use the FILESET statement to specify multiple filesets to be placed on a pool. \nUser group host: Bob Oesterlin\nSpeakers:\n\n\n\n\n Speaker NamePhotoBio\n\n\n\n\n Nils HausteinNils Haustein is Senior Technical Staff Member with IBM Systems.

Using a remote mount attached file system\, CNSA provides a persistent data store to be accessed by the applications via the IBM Spectrum Scale Container Storage Interface (CSI) driver using Persistent Volumes (PVs). This talk provides a field update on CNSA and a deep dive on technical aspects of this technology.\n  \n \n \n \n \n \n \n \n \n \n \n  \nDownload slides here \nQ&A\nHow does the entitlement key work for partners looking to run in their labs for educational purposes?\nThe way it’s currently set up is that we require entitlement (a purchase) of Data Management Edition (DME) or Data Access Edition (DAE) in order to gain access to the container images. If you are entitled to these editions of Specturm Scale\, the container images should be accessible via the entitlement key. \nWhat is with air gap installations?\nThe switch to IBM Cloud Registry (ICR) improves air gap installations as you can replicate the container images in the same way as you do with your OCP images.for details\, please see https://www.ibm.com/docs/en/scalecontainernative?topic=appendix-airgap-setup-network-restricted-red-hat-openshift-container-platform-clusters. \nIs it mandatory to have access to IBM Cloud or GitHub site? What if we have a secure site?\nThere is an air gap install available. You can mirror the registry and pull the images yourself and then serve them internally to your own OpenShift cluster. For GitHub\, you would take the command-sets\, pre-download the yamls and then use them internally. You would need these all before starting your install on an air gap setup. \nNow CNSA only supports mounting one remote filesystem. Is it foreseen to deploy NSD servers in OpenShift pods in the future? Moreover\, one worker node can host just one Core pod\, because cluster and node files are put in directories mounted from the host in order to make them persistent. If you have a bare metal cluster with\, say\, static physical machine worker nodes\, you are forced to deploy just one Core pod per node even if your physical node can provide computing resources to host multiple Core pods.\nWe’re looking at ECE and shared nothing local disks. You will first see some of this in the Spectrum Fusion product and then into our CNSA side of things. You’ll also see more filesystems available for remote mount. \nIs it foreseen to make multiple Core pods deployable on the same worker node in future releases?\nNot anytime soon. We will look into this once we managed to get rid of the kernel module and support FUSE based deployment. We are working on FUSE but have no timeline so far. \nWhat’s the support for other types of containers like? Singularity for example?\nCurrently we’re sticking with the K8s related environments but we have heard other requests for Singularity. \nFor CNSA a integration of CSI are great but importantly rolling update is a must.\nAgreed. We’re working on rolling upgrade!!! \nIf you have a fixed number of bare metal worker nodes\, and one node fails\, it would be useful to start the lost Core pod on one of the remaining worker nodes.\nWell\, we are infrastructure not an application. With current CNSA (remote mount) we are basically just an interface to the storage cluster. One per pod is fine. Down the line when we add local storage it would be nice to reschedule a failed pod to another node\, but unfortunately this does not work either cause it cannot transfer the disks. \nWhen will the Helm charts for CNAS 5.1.1.1 available.?\nMeanwhile they are available here:\nhttps://community.ibm.com/community/user/storage/blogs/gero-schmidt1/2021/07/02/helm-charts-ibm-spectrum-scale-container-native\nNote that in the future\, we’re going to combine CSI/CNSA installs in order to simplify things. At this point\, HELM will be less necessary as well. \nRelated material\n\n\nEpisode 8: Scalable multi-node training for AI workloads on NVIDIA DGX\, Red Hat OpenShift and IBM Spectrum Scale\nEpisode 6: Persistent Storage for Kubernetes and OpenShift environments\nEpisode 3: Spectrum Scale Strategy Update\n\nUser Group Host: Simon Thompson\nSpeaker\n\n\n\n\n Speaker NamePhotoBio\n\n\n\n\n Laura O.
