[rdiff-backup-users] rdiff-backup Input/output error

[Thomas S. Dixon]

Greetings all,
I have 2 questions, but first some background. We've been using 
rdiff-backup for about 6 months and it's been fantastic. Unfortunately, 
we lost some disks in our storage enclosure (which held the rdiffs) and 
had to start from scratch. I have now restored the rdiffs back to the 
enclosure from tape. Rdiff-backup lists all the increments fine. 
However, now I'm trying to run a subsequent backup to the restored 
rdiff-backup location and it errors immediately. I believe that the 
pertinent error is this:

OSError: [Errno 5] Input/output error: 
'/backup/yellowstone/rdiff-backup-data/rdiff-backup.tmp.0'

So I have 2 questions. First, what is the function of this 
rdiff-backup.tmp.0 file? I'm guessing it's a temp file used only by 
rdiff-backup during a backup. My first thought were permissions, maybe 
rdiff-backup couldn't create this file, but I was able to create it 
manually. Second question is: What kinds of things might cause this 
OSError? I've already looked at permissions and they seem fine.

I've tried searching the list archives and google, but have been 
unsuccessful. Thanks in advance for your help.

-Tommy
