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...

AFM Azure Blob direct support

For data exchange, data access from multiple sites and also access of data from within Azure we would like to use Spectrum Scale AFM connected to a Azure blob similar as connected to S3 storage. Currently this will require a S3 / Azure converter l...

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 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...

List and stop long running commands

Some Spectrum Scale commands can take a long time to run, such as mmapplypolicy, mmrestripefs, mmecheckquota. These might be run manually, or started by cron a batch system, or a callback. But sometimes, once started, there is a need to stop the c...
