Similar problem to https://bugzilla.redhat.com/show_bug.cgi?id=1188064
With log-level set to ERROR, I still get logs like this
[2015-07-25 02:06:11.206465] [MSGID: 114031] [client-rpc-fops.c:1300:client3_3_removexattr_cbk] 0-gv0-client-0: remote operation failed: No data available [No data available]
I notice that xlators/protocol/client/src/client-rpc-fops.c line 1293 of 3.7.2 source, loglevel is set to 0. The 3.6.4 source set this to GF_LOG_DEBUG.

logging: client3_3_removexattr_cbk should not log expected ENODATA
Commit 379dbbfd changed the log level of an expected error message from
GF_LOG_DEBUG to '0'. This causes the message to always get logged. It is
intended to log the warning when the xattr could not be removed (but
exists), removing a non-existing xattr is sufficient as debug.
