[Gluster-devel] Locking Problem with Mozilla Firefox

[Torsten.Schulle at ksk-stendal.de]

Hi glusterfan's,

I mount the /home directory with gluster. If I start Mozilla Firefox, I get
some lockings errors.

2008-05-10 17:53:01 E [fuse-bridge.c:2361:fuse_setlk_cbk] glusterfs-fuse:
16695: ERR => -1 (11)

On every start of Firefox, I get this error. I like to use the server for
many user. If ervery user start Firefox on ervery day I get many errors in
the logfiles.

I test the situation a one server. Glusterserver and Glusterclient are on
the same machine.

My idea for the future is to replicate some important directories (also
/home) on two server per afr. At the moment i test it ony on one server.

In the first i test it without the posix-locks feature, but then i get also
problems with openoffice (The start of openoffice freeze!).
If i use the posix-lockes feature openoffice works fine. Only Firefox
produce errors.

I use opensuse 10.3 with the update's from 09.06.2008

Kernel: 2.6.22.17-0.1-bigsmp
fuse-2.7.2glfs10

My server is a Proliant DL380G5 with 8GB memory. HDD Proliant P400 Raid5
Controller with 4x72GB.

My question:

Is my configuration wrong?
Can I use any options to correct the problem?
Can I ignore the error's?
Can I suppress the error's?
