Hi!

Just a question about RO/RW copies.
We have set up 3 volumes for every user (home, work, ftp) and few others
with CVS, svn, data,...
For easy backup we've made RO copies of nearly all volumes.
But now, with 2 database servern and all the RO copies, we run into a
problem not thought about before.
With the 2nd database server in the cellservdb, most machine use the RO
copies of the volumes. With some volumes (archive, cdonline) that's OK
for working (but hey, these data isn't really small to hold a RO copy),
but with CVS, svn or home dirs, a RO copy-mount isn't really nice.
How can we be sure, to have RW Access to these volumes?
It would be nice, if OpenAFS would loadbalance the read to all the RW &
RO volumes, but write only to the RW volume and than automaticly release
this volume...
The only dirty solution I found is to mount the root.cell volume RW as
/afs/.url.to.domain to have guranteed RW access to the volumes.

Cya
Lars
