Hi,

Linux-2.6.16-rc6 already includes OCFS2. Although the whole thing
still feels a bit fragile in various failure cases, it basically works,
after applying the trivial patch to drbd-8.0_pre1 !!

[root at hans:~]# mount
[...]
configfs on /sys/kernel/config type configfs (rw)
ocfs2_dlmfs on /dlm type ocfs2_dlmfs (rw)
/dev/drbd0 on /mnt/ha0 type ocfs2 (rw,_netdev,heartbeat=local)

[root at wurst:~]# mount
[...]
configfs on /sys/kernel/config type configfs (rw)
ocfs2_dlmfs on /dlm type ocfs2_dlmfs (rw)
/dev/drbd0 on /mnt/ha0 type ocfs2 (rw,_netdev,heartbeat=local)

[root at hans:~]# cat /proc/drbd
version: 8.0_pre1 (api:80/proto:80)
SVN Revision: 2121M build by phil at hans, 2006-03-14 18:52:04
 0: cs:Connected st:Primary/Primary ds:UpToDate/UpToDate
    ns:65967306 nr:3711385 dw:3905635 dr:65806949 al:178 bm:4015 lo:0 pe:0 ua:0 ap:0

        act_log: used:0/257 hits:42025 misses:178 starving:0 dirty:0 changed:178
 1: cs:Unconfigured

Finally it is possible to mount the FS on both nodes _concurrently_ !

PS: This is only the first message of success, there are many bugs to
    find and fix still in DRBD-8.0_pre1 !
