Recovering a Failed Fileserver
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If a fileserver crashes, take the following steps to ensure it's
usable after recovery:
* Pause mirror updates and volume release cron jobs
* Reboot the server; fix any filesystem errors and check the salvager
logs
* Check for any stuck volume transactions; remedy as appropriate
* Perform a manual release of every volume from a terminal on a server
using "-localauth" in case OpenAFS decides it can't do an
incremental update.
* Re-enable cron jobs
