[Gluster-devel] glusterfs 1.3.9 - Could not acquire lock "[Errno 38] Function not implemented"

[Amar S. Tumballi]

advisory locking and mandatory locking support is present in posix-locks
translator, you need to load it on server spec file...

something like below

volume posix
  ...
end-volume

volume plocks
  type features/posix-locks
  subvolumes posix
end-volume

..
..
..
volume server
  type protocol/server
  option auth.ip.plocks.allow *
  subvolumes plocks
end-volume

and from the client connect to 'plocks' volume (using option
remote-subvolume).

Regards,
Amar

PS: I will be updating wiki with fully loaded production system's volume
spec file. So, we can reduce the basic translator positioning mails. Sorry
for not doing it till now.. i am bit lazy
