Storage Maintenance Update re: aggr14

Former user posted on Jul 05, 2017

The aggr14 storage volumes are still offline.

Recall our last post, Scheduled Outage of Some Storage Volumes with work being tracked here: ITDEV-3403 - Getting issue details... STATUS

The filesystem check triggered an error in the IBM GPFS code:

Fri Jun 30 13:32:17.106 2017: [X] logAssertFailed: dataPtr.chunkPrevI(nextI) == prevI && chunkCount <= nChunks
Fri Jun 30 13:32:17.107 2017: [X] return code 317, reason code 1729, log record tag 65535
Fri Jun 30 13:32:23.425 2017: [X] *** Assert exp(dataPtr.chunkPrevI(nextI) == prevI && chunkCount <= nChunks) in line 2997 of file /project/sprelttn423/build/rttn423s001a/src/avs/fs/mmfs/ts/classes/basic/suballoc.C

The IBM technical support staff indicate this is a bug that requires a software patch, which they are working on.

Volumes will remain offline until we deploy the patch, re-run the filesystem check, and migrate the data. We will keep you posted as we hear from IBM.
