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 version). Clients vary from AFS 3.6 on AIX 4.2 to OpenAFS 1.4.4 on Solaris 10, but the vast majority is OpenAFS 1.4.1 on Scientific Linux 4. . afsdb upgrade : 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 same name. As I tried to be smart, in order to avoid CellServDB manipulations on our whole farm (hence reboots) I played with "fs setpreferences" to higher 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 until now. 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 discrepancies ? . fileserver upgrade : First step as been to stabilize versions on all the fileservers and OS. As we had 1.2.13, It seemed a good step. Should I upgrade fileservers, then afsdb servers ? I went the other way, it seem a bad idea. Any advice welcomed ! X.
