[OpenAFS] Error reading diskDataHandle vol header

[Staffan Hämälä]

We had a crash on an AFS server yesterday. Afterwards, I noticed that vos listvol had these lines in the end:
---
**** Could not attach volume 538592892 ****
**** Could not attach volume 538592823 ****

Total volumes onLine 1618 ; Total volumes offLine 2 ; Total busy 0
---

I've not been able to find any information about those two volumes. The vldb seems not to know anything about them:
$ vos exa 538592892
Could not fetch the entry for volume number 538592892 from VLDB 
$ vos exa 538592823
Could not fetch the entry for volume number 538592823 from VLDB

Looking at the server logs, I find the following:
SalvageLog:
...
04/23/2012 17:30:16 SALVAGING VOLUME 538592823.
04/23/2012 17:30:16 totalInodes 4
...
04/23/2012 17:30:17 SALVAGING VOLUME 538592892.
04/23/2012 17:30:17 totalInodes 4
04/23/2012 17:30:17 SALVAGING OF PARTITION /vicepb COMPLETED

And, even though the salvager had run just a little while before:

What should I do with them?

They might even have been there for a long time, without anyone noticing before now.

The server is a Redhat RHEL 4, running openafs 1.4.12.
