Mysql version: 5.0.51a-24+lenny1
Glusterfs version: 2.0.6

end-volume
volume locks
type features/locks
subvolumes posix
end-volume
volume brick
type performance/io-threads

subvolumes locks
end-volume
volume server
type protocol/server
option transport-type tcp
option auth.addr.brick.allow 192.168.222.*
subvolumes brick
end-volume
And here my glusterfs.vol:
volume ha1
type protocol/client
option transport-type tcp
option remote-host fs-1
option remote-subvolume brick
end-volume
volume ha2
type protocol/client
option transport-type tcp

subvolumes replicate
end-volume

option cache-size 512MB
subvolumes writebehind
end-volume
Logfiles:
On starting mysql now on cluster-1 (there is nowhere any other instance and I also tried out remounting it):
