CNSA Support for Per-PV Encryption

Add support for Scale CNSA to provide per-PV encryption allowing for each PV to use its own encryption key from GKLM or HashiCorp Vault. This would be configured as part of the encryption config CR for the PVC. Allow for each fileset associated wi...

CES support on SLES 12 SP3 Little Endian

Recompile the CES packages to support SLES 12 SP3 on Power 8 and newer processors. There is already support in place for RHEL, but some customers are using SLES as their primary OS primarily due to SAP Hana installations and there is no support fo...

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...

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...

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 ...

Spectrum Scale capability to remote mount filesets

implement ability to remote mount a fileset instead of a full filesystem

Storage Scale - Need GPFS to support storing or exporting performance data into enterprise-level time series database like InfluxDB or Prometheus

Problem: 1. The "pmcollector" service usually cannot work well when the GPFS cluster has over 100 nodes. As a result, the GUI will not display the performance data normally. And restarting the GUI will not help.2. ZIMON can not process large amoun...

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...
