Data inegrity checksum on stored data

In the time of Big Data the storage solutions are increasing in magnitude. With the growth of the data the risk of being hit by a silent data corruption also increases. Spectrum Scale itself does not check the data integrity stored on the NSD. It ...

"Too Many Groups" - Need to increase the amount of GIDs for Scale Linux from the current limit of 1020.

if a person was a member of more than X groups, they couldn't access the GPFS filesystem. The customer opened a ticket about it with IBM. This would have been awhile ago – 2019 or so? I don't have the ticket number. Census has quite a few projects...

Allow group owners to also query filesets

We have user filesets (independent) that are owned by root but the group is actually the user. Unfortunately Spectrum Scale seems not to take group ownership into account and only the owner can query the fileset (mmlsfileset) which seems overly re...

Support 256 or more cluster watches per cluster.

Only 25 cluster watches are supported per cluster, but we need 256 at least.

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...

extend number of independent filesets

For a file system used in a large research facility with a capacity beyond 20 PB, we would like to generate at least 5000 independent filesets for projects being active in processing and generating data. We expect initially a demand for 5000 indep...

Request to add "all" option to put filesystem in maintenance mode

In order to shutdown/startup gpfs gracefully, it is recommended to put filesystem in maintenance mode using "mmchfs --maintenance-mode" cmd before shutdown. However, this command allow only one filesystem at a time. So if the customer has many fil...

Storage Scale and Spectrum Archive: If a pre-migrated or migrated file is deleted, provide a limited window to recover it without having to use Storage Protect

Current documentation states that for a space-managed fileset if you use snapshots it triggers a recall of the data from tape to disk. The University of Michigan was always told this is a limitation in Storage Scale not Spectrum Archive and that t...

add --auto-inode-limit for independent filesets

In Storage Scale 5.1.4 mmcrfs/mmchfs introduced the --(no)auto-inode-limit switches. Unfortunately this only works for whole filesystems and cannot be finetuned for individual (independent) filesets. There are situations where you have a mixed env...

Add mmchfileset feature to make a fileset temporarily read-only

When migrating data, we need to be able to guarantee that no data in a fileset has been modified during the duration of the migration. Adding a feature to mmchfileset which can make a fileset read-only on a temporary basis would fulfill that requi...
