[Gluster-users] Write operations failing on clients

[Alex]

Okay, I did some digging. On the client there was many errors such as:

[2015-04-29 15:47:08.700174] W [client-rpc-fops.c:2774:client3_3_lookup_cbk]
0-img-client-0: remote operation failed: Transport endpoint is not
connected. Path: /www/img/gallery/9722926_4130.jpg

0-img-replicate-0: looking up /www/img/gallery/9722926_4130.jpg under
img-client-0 failed (Transport endpoint is not connected)

And at the same time on the cluster:
[2015-04-29 15:47:59.989897] W [client-rpc-fops.c:2774:client3_3_lookup_cbk]
0-img-client-0: remote operation failed: Transport endpoint is not

What could it mean? Is there some kind of network error? BTW there was
nothing that indicated any network connectivity problems between nodes and
clients.
