ugh. ocfs2 may not do for us. it does not support quotas..i have to check if

there are more than 247 unique ip addresses across 4 networks so i think we 
are ok there :)

please keep in mind that you will need multiple ip addresses to achieve
that as you're limited to approx 64k usable ports and therefore
connections in tcp.


for gfs (or better gfs2): i did not succeed in getting it up and
running. ocfs2 has been no problem.

i had a small talk with the developer of drbd where i came to the
conclusion that i should favor ocfs2 anyway.
