volume rebalance: md1: success:
but no change on the bricks for the directory, still empty except on 2 bricks.
Should I remove files in the .glusterfs directory on the 2 bricks associated to
these "---T" files ?
Thanks,
A.

so that might be the reason of error. How can I fix this ?
The '----T' files are DHT link-to files. The actual files must be
present on the other distribute subolumes (tsunami 1-2 or tsunami 5-6) in
the same path. But since that doesn't seem to be the case, the something
went wrong with the re-balance process. You could run `gluster volume
rebalance <volname> start+status` again and see if they disappear.
Thanks,
A.

Just noticed that your `gluster volume status` shows that rebalance was
triggered. Maybe DHT developers can help out. I see a similar bug[1]
has been fixed some time back. FWIW, can you check if "

Should I run "gluster volume heal md1 full" ?
Hi Alessandro, Looks like there is no pending-self heals, so no
need to run the heal command. Can you share the output of the client
(mount) log when you get the ENOTEMPTY during the rm -rf?
What version of gluster are you using? Thanks, Ravi
Thanks,
A.

Is there a cure such as manually forcing a healing on that directory ?
Are all bricks up? Are there any pending self-heals ? Does
`gluster volume heal md1` info show any output? If it does, run 'gluster
volume heal md1' to manually trigger heal. -Ravi
Many thanks,
Alessandro.
