Gluster users - Dec 2010 - [3.1.1] NFS sparse file corruption problems?

Any known issues with replicated volumes, sparse image files exported via NFS?

I can install a xen virual machine (XCP), a can boot it 2 or three times, 
after that ext3 seems complete corrupted, I'm unable to boot from the image.

I can see jdb kernel messages regarding the journal, it seems missing.

I do some install tests now to see if it is reproducable or not, and if it 
appears  if i do native glusterfs mounts instead of nfs mounts.

Thanks
Christian

The boot partitions file system is clean, there's no write access.
The  root partitions file system is corrupted after some write access, kernel 
panic.

It is reproducable.
No tests on a native glusterfs mount possible, virtual disk creation fails, 
maybe due to O_DIRECT?

open("/var/run/sr-mount/93bc8d22-3a8d-c62a-21c4-c512a150c3a0/test.vhd",
O_WRONLY|O_CREAT|O_TRUNC|O_DIRECT|O_LARGEFILE, 0644) = -1 EINVAL (Invalid 
argument)
