Hi guys, I lost a brick in a 2x replicated system. The volume is 17TB with 9TB used ( small files ). 3 drives failed in 2 hours in a raid-5 array. Gluster version: 3.8.15 So "reset-brick" isn't available on this version. I've googled all weekend and I'm overwhelmed so I'd like to verify before I muck everything up. Is this the correct procedure to restore the failed brick? # Replace drive # Use parted to create /dev/sdb1 # Make xfs filesystem on /dev/sdb1 # Mount /var/glusterfs/sdb1 # gluster volume replace-brick myvol d-es2-nfs-a:/var/glusterfs/sdb1/myvol d-es2-nfs-a:/var/glusterfs/sdb1/myvol commit force I read about using different brick names but again, I’m overwhelmed with all the info on google. I also saw something as simple as remove failed and re-add as new but…. Now I just read about xfsdump | xfsrestore to preload, but how would that work with healing? Thanks a ton in advance.
