[Gluster-devel] Strange inconsistencies (No such file or directory)

None of those are symlinks at all...  There is settings in Dovecot to use
harlinks to maintain names, but that option is turned off...  still same
issue, I think Dovecot might be using a symlink temporairily when moving
the messages from the new folder to the cur folder.  In IMAP messages that
arrive go into /mail/mydomain.com/webmaster/new/ and then the mail server
moves them into /mail/mydomain.com/webmaster/cur/ once you check for new
messages...  This issue only happens when I check email from one server
and it moves it into the cur folder....  that is when the other server can
not access it unless I restart glusterfs on the client having the access
