Thank you all for this. Unfortunately I wasn't able to try this. In my
attempt to change the brick name, I noticed I'm on Gluster 3.13 (Not a
typo) . So I proceeded to update to 6.10 then from there, to 9.4. To
6.10 it went fine however from 6.10 to 9.4 everything blew up. I got a
torrent of error messages. Struggled on it for several hours but no luck.
So I ended up blowing up the cluster after copying the data out to a
single drive, then copying it back to the Gluster 9.4 cluster once the
cluster was ready. Would have loved to debug to see what to do about
each error but I simply ran out of time and needed to get the cluster
back up quickly. ( Still have most of the logs if interested but without
some context, it would be somewhat meaningless. )
Nontheless, I'll keep the notes below. I have a few more Gluster
clusters to work on.
Cheers

Hi Tom,
I think you could use the replace-brick sub-command; like: "gluster
volume replace-brick <vol> <host>:/bricks/0/gv01
<host>:/bricks/0/abc-gv01 commit force"
see;
https://docs.gluster.org/en/latest/Administrator-Guide/Managing-Volumes/#replace-brick
Kind regards,
Olaf

Hi,
I use the sequence below to move a brick to a different peer. I
assume it also works for renaming a brick (just put peer01 =
peer02 = whateveryourpeeris). I used this on a distributed-only
volume (no replication) running glusterfs 9.3.
Please note that I didn't to extensive tests and I didn't find any
documentation if this is officially supported.
best wishes,
-Stefan
#----------------------
# stop glusterfsd for brick:
gluster v reset-brick gvol peer01:/old/path start
# in your case, you probably want to do something here like
mv /old/path /new/path
# add the moved path as new brick:
gluster v add-brick gvol peer02:/new/path force
# Order is important!
# if brick is removed before other brick is added,
# will lead to duplicate files.
# remove old brick (which does not exist any longer)
gluster v remove-brick gvol peer01:/old/path force
# probably not necessary in your case:
gluster v rebalance gvol fix-layout start
