Description Joe Julian 2012-05-27 19:57:54 UTC 
Version: 3.3.0qa34

clear-locks commands fail if rpc-auth-allow is not set as it attempts to connect via privileged port.

The CLI reports the error as:
Volume clear-locks unsuccessful
clear-locks getxattr command failed. Reason: Transport endpoint is not connected

### glusterd.vol.log has
[2012-05-27 12:54:33.217491] E [rpcsvc.c:491:rpcsvc_handle_rpc_call] 0-glusterd: Request received from non-privileged port. Failing request
Comment 1 Joe Julian 2012-05-28 06:49:01 UTC

Each of these logs are for just the minutes that were in the clearlocks log. Let me know if that's not what you needed.
Comment 6 Amar Tumballi 2012-12-21 09:45:35 UTC 
one of the work around is to make sure everything works by adding "rpc-auth-allow-insecure yes" in volume files (both glusterd.vol and glusterfsd.vol, for which one can do 'gluster volume set <VOL> server.allow-insecure yes').

as the work around exists, would like to move the priority to medium.

The above patch is the only way at the moment to fix these things.

Also, Would like to close the bug with D(ocumentation)P(ending) flag set, once we have more better way of handling security (SSL/Kerberos etc), this issue will go away.
Comment 8 Amar Tumballi 2012-12-27 06:11:22 UTC 
as per comment #7 (WORKSFORME always when we have the above two options set). WONTFIX the part of not having these options set for now.
