[OpenAFS] disaster recovery
Wed, 20 Sep 2006 16:16:48 +0300 (EEST)
Thnank you for your tips,
So far i was able to either restore from the backup or salvage most of the
data. However I would like to recover some of the most recent bits that are
currently lying in lost+found. Is there a way?
We do have ro copies of all volumes. Unfortunately vos release stopped
working about a month ago. Possibly due to the same reasons that resulted
to yesterday's disaster.
