I just read that... Anyway, I hope that it's possible. I'm with you since I don't see a point in a clustered file system if you can't take a node down by plan. Not only to upgrade GlusterFS, but the entire system. I've done rolling upgrades of point releases without issues (replica 3 volume), so long as you're slow and methodical I don't think its an issue.
Major upgrades of any system tend to involve pain - I know the
ceph upgrade from Hammer to Jewel (9.x - 10.x) was a non trivial
procedure that involved taking the cluster down. -- Lindsay Mathieson |
