Pinned topic Flashes (Alerts): IBM Spectrum Scale (GPFS): mismatched replicas with possible undetected data corruption following restripe operations (restripefs)

‏2018-08-22T19:12:06Z |

Problem Summary:

In a file system where data or metadata replication is used and "rapid repair" is enabled, and when there are "update in place" activities after disk(s) go down, followed by use of the restripefs command with options -r/-R/-m, mismatched replicas may be created after some disks are started up.  Some replicas with stale data could result in metadata corruption in the file system, or data loss.
