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 ...

eliminate lack of I/O on mmdelsnapshot start

When deletion of bunch of snapshots starts we a lack of I/O for about three minutes.NFS Clients see a huge delay of I/O. Related applications hanging for this time and user connections and run into timeouts (e.g http connections for apps that stor...

Introduce effective quality management

During the last year, we saw many new ISS code levels, most of them with critical errors that could lead to data corruption or data loss. Fortunately, many costumers were spared from data corruption, but they had to update Scale nearly monthly to ...

Enable multi protocol CES SMB / NFS rolling upgrades when CTDB upgrade is within a minor version.

When a multi protocol SMB and NFS CES cluster is upgraded, a short full stop of all CES protocols is required due to CTDB not allowing mixed major or minor versions. This can often cause issues with NFS mounts, if it is not possible to unmount the...

Add quota logging capability to keep overall quota accounting consistent

For performance, nowadays, most of quota information is stored and updated in memory. Then, it will be synced back to disk in an asynchronous way later. However, there isn't a recovery mechanism for GPFS quota in abnormal situations. These can mak...

network access controlm for mmsysmon REST API

Currently mmsysmon REST API allows all inbound connections. Our cybersecurity penetration team has successfully sent network packets that caused REST API to malfunction, leaving hundreds of connections in CLOSE_WAIT state. In this scenario CherryP...

Remove Node Feature in Spectrum Scale CNSA

Currently in the CNSA Implementation there are no way to reduce a define CNSA-Cluster to one or more Nodes, like a mmdelnode step. The Operator has no function to do these necessary step to reduce a cluster with these request.

Quota calculation and capacity presentation based on files size

User quota and file set quota are calculated based on allocated capacity on GPFS (kb_allocated). If files are moved to an external tier, e.g. by transparent cloud tiering, the file system utilisation will be decreased. Storage admins should have t...

To simplify the deployment of workloads in the cloud, IBM must improve the performance of the Scale command "mmaddnode" to allow for faster spin up/down of resources.

Nodes in the cloud need to be spun up quickly as needed. Currently mmaddnode takes too long to add a significant number of nodes as it sequentially adds nodes to the cluster; not only that, but other commands like mmchlicense, mmchnodeclass, and m...

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 ...
