Please report this as a bug, the above should not be needed after
dist-upgrading.

Nailed it!

update-rc.d -f o2cb remove
update-rc.d -f ocfs2 remove
update-rc.d o2cb defaults
update-rc.d ocfs2 defaults

did the trick. Perhaps this is a leftover from Jessie...

Before:

$ ls -al /etc/rc*.d/*o2cb
lrwxrwxrwx 1 root root 14 Sep 10 15:08 /etc/rc0.d/K02o2cb -> ../init.d/o2cb
lrwxrwxrwx 1 root root 14 Sep 10 15:08 /etc/rc6.d/K02o2cb -> ../init.d/o2cb
lrwxrwxrwx 1 root root 14 Sep 10 15:06 /etc/rcS.d/S13o2cb -> ../init.d/o2cb

$ ls -al /etc/rc*.d/*ocfs2
lrwxrwxrwx 1 root root 15 Sep 10 15:08 /etc/rc0.d/K01ocfs2 -> ../init.d/ocfs2
lrwxrwxrwx 1 root root 15 Sep 10 15:08 /etc/rc6.d/K01ocfs2 -> ../init.d/ocfs2
lrwxrwxrwx 1 root root 15 Sep 10 15:06 /etc/rcS.d/S14ocfs2 -> ../init.d/ocfs2

$ ls -al /etc/rc*.d/*ocfs2

Thanks for pointing out the right direction!

Thank you. Tried that -- no difference.

I thought about it too, but according to /etc/init.d/o2cb and
/etc/init.d/ocfs2 they seem to start after $network:

Nothing there:

$ journalctl -b -u o2cb.service
-- Logs begin at Tue 2017-09-19 10:13:16 CEST, end at Tue 2017-09-19
11:17:01 CEST. --

$ journalctl -b -u ocfs2.service

Thanks.

Missing "_netdev"?

Maybe o2cb and ocfs2 need to be ordered after network-online.target?

Any output after a failed boot from "journalctl -b -u  o2cb.service" or
"journalctl -b -u ocfs2.service"?
