Re: set volume locking without shutting off server

Hi Kaushal,


I’m using 

->gluster --version
glusterfs 3.5.2 built on Aug  6 2014 19:33:49
Copyright (c) 2006-2011 Gluster Inc. <http://www.gluster.com>

and the generated brick.vol has this line(s)

volume dnas_volume-locks
    type features/locks
    subvolumes dnas_volume-access-control
end-volume

and you are right. No these aren’t NFS mounted, that was poorly worded. Should I just update glusterfs that should resolve my problems? Or am I still missing something.

Thanks,
Jordan

Which version of GlusterFS are you using?

The locks translator should be enabled by default for all volumes for
the latest versions (IIRC 3.5 and above). So you wouldn't need to do
anything. To verify you can check the generated brick volfiles in
/var/lib/glusterd/vols/<VOL>/<brick-name>.vol .

Also, are you really creating GlusterFS bricks on NFS mounts? That
doesn't work..

Hi,

Is it possible to enable posix type locking with glusterfs without shutting
off the volume?

I think this is what I need (I’m trying to get sqlite to lock files on my
nfs mounted glusterfs volume)

volume locks
 type features/locks
 subvolumes brick
end-volume


Can you enable this with the gluster volume set command in some way? If not,
do I just add those lines to the /etc/glusterfs/gluster.vol file and turn
off and on the volume, or how would I reload that file. I manually started
the current fs with the following. I’m confused on where I should actually
enable the locking.


gluster volume create  myvolume nfs_mount_1 nfs_mount_2 …nfs_mount_N
gluster volume start myvolume


Thanks so much,
Jordan
