Normally if a read only replica exists it will be mounted by preference. The usefulness of r/o replicas is in fact dependent on / afs mounting read-only by default.
Usually one creates an explicit read-write mountpoint for the cell (/ afs/.cell vs. /afs/cell) while the initial root.cell and root.afs are still not replicated. Once you have the latter, you can always create a read-write mount for root.afs or other volumes. (-dynroot should do this automatically)
If you have inadvertently created a cell without a forced r/w mount in your root.afs, there are two ways to fix it:
- create such r/w mount in some other cell that has an r/w mount and knows how to reach yours (requires you to auth to *your* cell, so crossrealm/cross-cell auth is not necessary, but you may need to insure that using your cell's Kerberos tickets won't cripple your access to the machine in the foreign realm/cell)
- bring up a client with -dynroot, which should get you an automatic r/w mountpoint, and fix the static mounts from there.
(Several years back when a combination of a corrupted r/w site for root.afs and a pair of inexperienced admins caused our /afs to suddenly become quite empty, afs didn't have dynroot. Luckily I had a test cell running which knew how to reach the main one, so I was able to repopulate root.afs remotely. These days -dynroot is almost certainly the best way to go for this.)
As for the difference between the two machines: you probably haven't restarted the client on the first machine yet, so its initial read- write mount of /afs is still intact. You should probably use that to make sure the /afs/.cell forced read-write mount of root.cell is present, and rerelease.
