We have the same setup, but it does not quite work as we supposed it
would. We thought that anything accessing the RO version would
automatically switch over to the other copy whenever to one it is
currently accessing drops out of the network, but it does not seem
to do
so. Perhaps there is a misconfiguration somewhere?
The situation is this:
RW version of volume X on volume server A
RO versions of X on servers A (on same partition as RW copy) and B
Now users' $HOME is, of course, the RW version (/afs/
blablabla/.username)
and programs using $HOME will complain when A disappears. Those
accessing the undotted version on the lost server should - to my
understanding - move over to using server B in a few minutes after
A is
lost, but they do not. Why is this?
The client never switches from an RW volume to the RO copy.
If you mounted the home dir with -rw, which you should and I'm sure
you did, your client will never switch to any other replica.
The replication is for read only data only, remember? ;-)
