[Gluster-users] Warning messages in client logs

[Prasun Gera]

Hello,
I set up a distributed storage on 3 nodes using glusterfs, and on a couple
of my clients, I am seeing a lot of these messages


[2014-09-29 06:34:16.549972] W

I am able to access these files though. Before these warning messages
start, there are informational messages which mention difference between
the server and the client versions.

The servers are running RHSS2.1 which I guess is based on 3.4 and one of my
clients is ubuntu and the other one is RHEL6.  The ubuntu client is running
the 3.5 ppa package and the rhel client is running the client included,
which is at 3.6 now. The RHEL client also prints out messages about missing
trash directories (in addition to these), which I guess is a 3.6 feature.
Does anyone know what's going on ? Googling around pointed me to self-heal
issues. I haven't run self heal and I don't even have a replicated setup.



Regards,
Prasun
