Hi, I have been asked to attempt recovery an old soon to be decommissioned openafs server. It is running openafs-server-1.4.7-68.2.SL4.x86_64 on Scientific Linux 4.4.
The RAID10 array (3ware Inc 9550SX) where vipepX partitions lie went completely missing while replacing a faulty drive (ECC error). We put the fauled drive back inside in order to be able to access the array again and rsycned all the vicepX date elsewhere. This was completed successfully. Errors logged meanwhile in the kernel logs mentioned sectors being repaired. The array was then deleted and remade with new disks and the data was rsynced back. However some volumes have not come online. Salvaging them causes them to deleted. These volumes have been off-line before the disk replacement attemp - so it is likely they have been corrupted for some time. bash-3.2$ bos salvage -server afs1 -partition vicepe -volume uk -showlog Starting salvage. bos: waiting for salvage to complete. bos: salvage completed SalvageLog: @(#) OpenAFS 1.4.7 built 2009-04-07 (68.2....@fnal.gov) 01/16/2013 17:14:45 STARTING AFS SALVAGER 2.4 (/usr/afs/bin/salvager /vicepe 536874966) 01/16/2013 17:14:45 2 nVolumesInInodeFile 64 01/16/2013 17:14:45 CHECKING CLONED VOLUME 0. 01/16/2013 17:14:45 uk (536874966) updated 01/09/2013 17:13 01/16/2013 17:14:45 No header file for volume 0 01/16/2013 17:14:45 totalInodes 6446 -bash-3.2$ bos salvage -server afs1 -partition vicepe -volume uk -showlog Starting salvage. bos: salvage completed SalvageLog: @(#) OpenAFS 1.4.7 built 2009-04-07 (68.2....@fnal.gov) 01/16/2013 17:15:22 STARTING AFS SALVAGER 2.4 (/usr/afs/bin/salvager /vicepe 536874966) 01/16/2013 17:15:22 The volume header file V0536874966.vol is not associated with any actual data (deleted) 01/16/2013 17:15:22 No applicable vice inodes on vicepe; not salvaged 01/16/2013 17:15:22 0 nVolumesInInodeFile 0 Temporary file /vicepe/salvage.inodes.vicepe.16945 is missing... /usr/sbin/vos examine uk Could not fetch the information about volume 536874966 from the server : No such device Volume does not exist on server afs1 as indicated by the VLDB Dump only information from VLDB uk RWrite: 536874966 number of sites -> 1 server afs1 partition /vicepe RW Site My question is, are there any other options to at least partially recover data from the offline volumes? I do have my last rsync of vicepe where this volume was. It was probably damaged before it was backed up but even a partial data recovery would help.
