[OpenAFS] AFS/OpenAFS incompatibilities ?
Fri, 21 Sep 2007 20:09:21 +0200
I am in the process of upgrading our AFS cell.
3 afsdb servers are AFS 3.6, on AIX old servers (getting rid off),
11 fileservers are OpenAFS 1.2.13, Solaris 9 (migrating OpenAFS and OS
Clients vary from AFS 3.6 on AIX 4.2 to OpenAFS 1.4.4 on Solaris 10, but the

In order to upgrade afsdb, I removed today an AIX box cleanly, installed a
1.4.4 OpenAFS bos using solaris 9 and pushed it in production, using the

level of the changed vlserver. Then I got reboots.
Fileservers and volservers seem to communicate correctly, but Linux clients
get stuck on several volumes at random then reboot. I could not get a trace
I'm going back right now : decommissioning the new solaris box and
re-setting the old AXI box up.
Are you aware of incompatibilities between mentioned versions ?
Do you spot any Big Stupid Mistake I made ?
Should I upgrade each db servers as closely as possible to avoid version

Any advice welcomed !
