------------------------------------
The files on both server nodes looks like the same and both getting changed
from the running VM on it! So perhaps only the extended attributes are
wrong.
Is there a way to change this manually? Without deleting the file on one
side.
I corrected manually on both server nodes the extended attributes to
"0x000000000000000000000000" like this:
setfattr -n trusted.afr.storage1-client-0 -v 0x000000000000000000000000
/srv/glusterfs/poolserver/hdb.raw
It worked!

Thomas
