[Gluster-users] remove-brick question

[james.bellinger at icecube.wisc.edu]

I inherited a system with a wide mix of array sizes (no replication) in
3.2.2, and wanted to drain data from a failing array.

I upgraded to 3.3.2, and began a
gluster volume remove-brick scratch "gfs-node01:/sda" start

After some time I got this:
gluster volume remove-brick scratch "gfs-node01:/sda" status
Node Rebalanced-files          size       scanned      failures

Two things jump instantly to mind:
1) The number of failures is rather large
2) A _different_ disk seems to have been _partially_ drained.
/dev/sda              2.8T  2.7T   12G 100% /sda
/dev/sdb              2.8T  769G  2.0T  28% /sdb
/dev/sdc              2.8T  2.1T  698G  75% /sdc
/dev/sdd              2.8T  2.2T  589G  79% /sdd



When I mount the system it is read-only (another problem I want to fix
ASAP) so I'm pretty sure the failures aren't due to users changing the
system underneath me.

Thanks for any pointers.
