If you are only looking for *detection*, it sounds like it is mature and working.  If you want automatic *correction* on a replicated volume (like you find in ZFS or BTRFS), that doesn't appear to exist yet.


I can't find an RHGS 3.2 admin guide, but I can find an RHGS 3.1 guide at

https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html/Administration_Guide/chap-Detecting_Data_Corruption.html

and it matches the information on the gluster.org BitRot Feature page.  They both say that automatic healing/correction is not available yet.  The Features page says it is not in scope for Gluster 3.7

But detection is still a valuable feature.  I'm sure correction will likely appear some time in the near future.
