Please ignore this. This was opened in error.

Comment 2 Anoop 2015-04-22 16:29:08 UTC

My bad, this indeed is an isssue. Cannot use the volume post detach.

Comment 3 Dan Lambright 2015-04-24 11:45:02 UTC

I cannot reproduce this.

Comment 4 Niels de Vos 2015-05-15 13:07:36 UTC

This change should not be in "ON_QA", the patch posted for this bug is only available in the master branch and not in a release yet. Moving back to MODIFIED until there is an beta release for the next GlusterFS version.
