Storage Scale (formerly known as GPFS)

Allow group owners to also query filesets

We have user filesets (independent) that are owned by root but the group is actually the user. Unfortunately Spectrum Scale seems not to take group ownership into account and only the owner can query the fileset (mmlsfileset) which seems overly re...

SMB transparent failover

The current design only support NFS transparent failover and SMB is not. Without SMB transparent failover, end user need to interactive with failover session. Customer hope to support CIFS session reconnect automatically during CES FO/FB. This can...

Support 256 or more cluster watches per cluster.

Only 25 cluster watches are supported per cluster, but we need 256 at least.

gpfs support mount fileset or directory

I hope that GPFS (General Parallel File System) supports mounting filesets or directories. Since each fileset or directory is used by different individuals, if mounting of filesets and directories is supported, it would achieve the effect of data ...

Reflink/ficlone support

reflink/ficlone is a system call for making clones of files, where all data blocks is initially shared, and changes are then done through copy-on-write/redirect-on-write. This can be done through "cp --reflink", or IOCTL_FICLONERANGE system call. ...

Data inegrity checksum on stored data

In the time of Big Data the storage solutions are increasing in magnitude. With the growth of the data the risk of being hit by a silent data corruption also increases. Spectrum Scale itself does not check the data integrity stored on the NSD. It ...

Storage Scale - A GPFS node with multiple nic drivers (ip addresses) should not be able to rejoin the cluster when the daemon interface is down

Our storage nodes have multiple nic drivers and IP addresses (RoCE network). When the nic for daemon IP is down (dev bond0), it will still keep trying to rejoin the cluster again and again, because its another nic (dev bond1) is still working. But...

add --auto-inode-limit for independent filesets

In Storage Scale 5.1.4 mmcrfs/mmchfs introduced the --(no)auto-inode-limit switches. Unfortunately this only works for whole filesystems and cannot be finetuned for individual (independent) filesets. There are situations where you have a mixed env...

Network resiliency enhancement - need mechanism for prioritizing control traffic over data traffic via QOS/PFC when RDMA is not enabled.

In a heavy workload situations, some clients are removed from the cluster as peer nodes are not able to communicate as heart-beat/control traffic stuck behind data traffic. Also explore, a dedicated VLAN(s) option for Control and Data traffic.

Storage Scale and Spectrum Archive: If a pre-migrated or migrated file is deleted, provide a limited window to recover it without having to use Storage Protect

Current documentation states that for a space-managed fileset if you use snapshots it triggers a recall of the data from tape to disk. The University of Michigan was always told this is a limitation in Storage Scale not Spectrum Archive and that t...
