Hi, 

It has happened, out hard drive hosting the coda data
had tiny smoke coming from it ...

We were able to recover most of the /vicep[abc] partitions to a new
hard drive, as well as the rvm partition. Some files on /vicepa 
had read errors and thus are missing on the new partition.

Main point is now: how do we ensure that this recovery worked ?

The old filesystem had errors on a number of files:

	 ./1/5b/18: Input/output error
	 ./1/5b/19: Input/output error
	[...]
	 ./1/5b/37: Input/output error

How do we find those files we have to get from the 96 hour old backup ? 
We'd like to keep those to a minimum, of course...

The server started fine, with the following kind of entries in SrvLog:

----
        13:47:05 Entering DCC(0x1000008)
        13:47:05 DCC: Salvaging Logs for volume 0x1000008

	13:48:03 SalvageFileSys: Therefore only resetting inUse flag
	13:48:03 SalvageFileSys completed on /vicepa

Are both volumes O.K. ?

It is followed by a number of transactions which looked kinda o.k.:

	13:48:27 recov_vol_log::SalvageLog: bitmaps are not equal

	13:48:27 Log rec at index 84 is unreachable

Later there are quite a few of 

	13:49:37 client_GetVenusId: got new host 129.70.139.110:2430
	13:49:37 Building callback conn.
	13:49:37 No idle WriteBack conns, building new one
	13:49:37 Writeback message to 129.70.139.110 port 2430 on conn 3316c35 succeeded
	13:49:40 RevokeWBPermit on conn 3316c35 returned 0
	13:49:40 ValidateVolumes: 0x7f000001 failed!
	[...]
	13:49:40 ValidateVolumes: 0x7f000059 failed!



Testing the filesystem with a 

	find /coda 

gave us 

	14:15:10 TryToCover: bogus link length

What does that mean ?

I appreciate any answer,
yours,
