[Gluster-users] problems with gluster 3.2.4

Tue Oct 25 17:05:18 UTC 2011

Top posting for visibility:

Here is the pertinent line in the log:

[2011-10-25 11:39:56.762720] E [glusterfsd-mgmt.c:628:mgmt_getspec_cbk] 0-glusterfs: failed to get the 'volume file' from server
[2011-10-25 11:39:56.762775] E [glusterfsd-mgmt.c:695:mgmt_getspec_cbk] 0-mgmt: failed to fetch volume file (key:/mnt)

Did you move your volume file or in some other way make it inaccessible for the client? The volume file tells the client essentially how to access files and directories on the GlusterFS – if the client can get that, the timeout is expected (it figures that the server has gone away and that you will try something different.

I suggest trying this mount line instead (assuming that your servers are named consistently:

                mount -t glusterfs gluster02:/volume01 /mnt/gluster

and see if you get the same message

hi,
      If the setup is not in production could you do "gluster volume set volume01 client-log-level DEBUG" and repeat the actions then post the logfile located at /usr/local/var/log/glusterfs/mnt-gluster.log on the client machine

Hi, we have 4 test machines (gluster01 to gluster04).

I've created a replicated volume with the 4 machines.

Then on the client machine i've executed:

mount -t glusterfs gluster01:/volume01 /mnt/gluster

And everything works ok.

The main problem occurs in every client machine that I do:

umount /mnt/gluster

and the

mount -t glusterfs gluster01:/volume01 /mnt/gluster

The client machine stops to respond, I cannot run a ls -l everything stops on the client machine.

It freezes for 120 to 300 seconds.

And then after this time I can return to type on the machine.

I type:

mount (enter)

And I can see the mount point.

But if I do cd /mnt/gluster
and then

ls -l

Everything freezes again.

There is no firewall installed, And I can reproduce this everytime in all our client machines.

Any idea how to start looking for the problem?

Best Regards
