[OpenAFS] Restoring ownership information of filesystem structure on /vicep*
Wed, 02 Aug 2006 14:39:49 -0400
Unfortunately the owner and mode information is vital information
about the files.. It's like asking "i just rm'ed this letter -- how
can I recover paragraph #3?". You should restore from backup.
> I've got a little problem regarding my OpenAFS server. I have migrated my server onto a new machine. For this purpose I had to move the /vicep* data to a temporary storage device.
> What I didn't know - until now - was that the raw AFS data files rely on file permissions and ownership information. Thus I haven't checked the correctness of the permissions after copying the data to the other harddisk.
> Now I've still got the correct owner/group/world permissions for the files but the ownership information is gone. It's all owned by root:root now.
> As a result I can't access all AFS volumes on the new OpenAFS server any more. Only a few are accessible. The others are marked for salvage but salvaging fails.
> So my question is if there is any possibility of recovering / fixing the ownership information of the raw AFS filesystem structure and where I could get information about how this file hierarchy on /vicep* is organised.
> Of course I've backuped all relevant data otherwise already. But I'd really like to keep the whole AFS volume structure intact.
> Thank you for any suggestions,
