[Gluster-devel] opendir gets Stale NFS file handle

[Emmanuel Dreyfus]

Hello

I observe this kind of errors in bricks logs:
[2014-09-30 03:56:10.172889] E
[server-rpc-fops.c:681:server_opendir_cbk] 0-patchy-server: 11: OPENDIR
(null) (63a151ad-a8b7-496b-92a8-5c3c7897e6fa) ==> (Stale NFS file
handle)

Here is the backtrace leading to it. Is that a real error?
