NSD client IO should have a time-out and a retry tunable per filesystem (JUMP Trading LLC)

The current Spectrum Scale configuration does not give the customer the ability to provide a timeout or retry values to NSD client IO. Since these tuning parameters do not exist, this can result in hung IOs or unexpected IO errors when the NSD ser...

Tools or self tune mechanisms for troubleshooting

Customers would like to have tools that would allow them to analyze our diagnostic information so they could more quickly determine what was wrong with the system and try to correct it (i.e. Self tune based on the latency and throughput of the net...

Prioritization of mmrestripefs -r block rebuilds

When a FPO mmrestripefs -r kicks off it should prioritize rebuilding blocks that have 2 duplicates missing over blocks that only have one duplicate missing.

Media read error to trigger auto rewrite

When a media read error is reported by a device a read from another replica should be followed by a rewrite to the original device to allow the devices LBA to use a different part of the device.

Option to avoid down drives

Option: when a device is down allows writes to blocks on the device to go to a different device rather than create a missed update. This protects the file system from large numbers of missed update blocks and retains full replica count.

Allow for separation of client services from storage services

Allow for the optional separation of the gpfs mmfsd process into a client process mmfscd independent of the gpfs storage process mmfssd. When something goes wrong with I/O subsystem in one node the applications on that node should still be able to...

GUI role for user with permissions to only manage Quota on Spectrum Scale

We have several divisions who would need to manage their own quota on Spectrum Scale. According to the IBM DEV Team and Lab Services, users with one of the following roles should have access to the filesets/quotas: securityadmin admin protocoladmi...

Overflow data placement

When creating a new filesystem with more than 1 pool, GPFS will guess where to put the file data. It would be nice if it was also capable of spillover to other pools, when the pool it guessed for here runs full: RULE 'default' SET POOL 'data' LIMI...

support filesystem metadata migration to 4K-based NSDs

Provide a transparent (e.g. no downtime) mechanism to introduce NSDv2 4k-aligned metadata NSDs into filesystems created with NSDv1 format NSDs.
