Storage Scale (formerly known as GPFS)

Auto expansion of inode to trigger once usage reaches around 95%

Today the Scale alerts and auto expansion are triggered when inode usage is very close to 100% and typically that means when the filesystem in use is very active and busy and is not optimal for performance. Would like to see the auto expansion of ...

Monitoring quota usage per fileset (not inodes, capacity usage)

Hi team, we found a gap in quota monitoring of spectrum scale filesets, we have the capability to monitor inode usage per-fileset, but not quota consumption in terms of capacity. Becasuse of that we urgently need a feature that could alert us when...

Restrict automatic node expels with deadlock amelioration with Nodeclass

We would like to possibly use automatic deadlock amelioration, but we need to ensure certain nodes are not expelled. We do not want to auto expel interactive/login nodes from the compute cluster. We already have a Nodeclass that contains these nod...

Allow RDMA device recognition possible at mmfsd run time

Sometimes, when mmfsd starts up, not all RDMA devices are available (mostly due to temporarily down links). When such a link comes up later, mmfsd would not detect that and consequently ignore the port for the current run. Only when recycled, mmfs...

NFS protocol nodes upgrade without disruption

Customer is having NFS being autheticated my MS AD. In this case SMB service needs to be installed and according to documentation, NFS outage is done when upgrading protocol nodes. Customer is requesting non-disruptive NFS protocol nodes upgrade a...

Support TLS 1.3 for use with IBM SKLM

Industry is requiring stronger current encryption levels.

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.

more useful output from mmrestripefs failures

It is possible, in a number of scenarios, to have a mmrestripefs operation fail when many disks are suspended and the filesystem is being restriped to bring the disks to the empty state. This is not an uncommon operation, especially when data is m...

zstd compression & dictionary support

If zstd support is added to the product it would be very interesting to allow for a few dictionaries to be used to improve (de)compression speed and compression ratio. This is ideal in situations where ILM policies can be written to target either ...

Allow mmrepquota -j to filter fileset(s)

The synopsis of mmrepquota looks like this: Synopsis mmrepquota [-u] [-g] [-e] [-n] [-v] [--block-size {BlockSize | auto} | -Y] {-a | Device:Fileset ...} or mmrepquota-j [-e] [-q] [-n] [-v] [-t] [--block-size {BlockSize | auto}] {-a | Device...} o...
