Hi List,
2 Servers - connected with crossover
my rpms:
gfs2-utils-0.1.38-1.el5
gfs-utils-0.1.12-1.el5
kmod-gfs2-1.52-1.16.el5
cman-2.0.73-1.el5_1.1

my hosts on both sites
192.168.0.1 node1
192.168.0.2 node2
my mountpoints
mkfs.gfs2 -p lock_dlm -t cluster:drbd -j 2 /dev/drbd0
mount -t gfs2 -o noatime,nodiratime /dev/drbd0 /test
(Btw: => drbd works fine as Primary/Primary)
ok, i can use /test on both sites and can write to files
and so on.

my drbd is no problem state is already primary (standalone)
Why can't i write to a gfs partition in the "lost Node" state ?
Now: i power node1 on !
drbd is no problem -> its recovered.
now i start cman
and my touch will be finished ....
Thanks for any ideas and help
