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...

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 ...

Storage scale performance statistics for SMB shares

EMS GUI (Monitoring > Statistics) only provides SMB performance statistics for cluster or node level. Having stats on each individual SMB share would be very useful. NFS shares have such stats.

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...

Report Spectrum Scale Event if FD hard Limit of Ganesha server is above the threshold.

Ganesha NFS server has a limit of max. open files, which is calculated by 80% of the maxFilesToCache parameter. If Ganesha Server is reaching this limit, Ganesha NFS server will stop working and all NFS clients will loose access to data. In curren...
