[Gluster-users] GlusterFS 3.1.1: "Permission denied" and "No such file or directory"

Dear all,

since the upgrade from glusterFS 3.0.0 to 3.1.1, some users have 
experienced strange problems. When they want to create a folder or a 
file, this usually works, but sometimes, it doesn't. The error message 
is something like "Permission Denied".

The permissions and ownership of the affected folders seem to be set 
correctly. I tried to chown -R user:group user/ anyway and it helped 
once. It even occurs that when jobs try to write output back from our 
batch system, most jobs can write files that are accessible, but a small 
number cannot write their output (to the same folder at the same time).

Another problem, that might be related to the ones above is that 
whenever a users tries to delete a directory, the following message occurs:

rm: cannot remove directory `test/': No such file or directory

but the directory is deleted anyway.

I've also seen files, that seem to have no permissions at all, e.g.

----------T  2 root root 4.1K Jan 17 10:26 mc_jpsi

This can be fixed manually, but is still very strange.

About our setup:

Volume Name: lemmy
Type: Distribute
Status: Started
Number of Bricks: 5
Transport-type: tcp

There is sufficient space left on all bricks. The operating systems of 
the servers are debian5 (once) and Ubuntu 10.04 server (4 times). The 
bricks have different filesystems (ext4 and xfs).

Thanks and Best Regards,
