I had a corrupted ReiserFS on one disk and another failed before I could fix it. I have transferred as much data from these drives to external ones as I could. Some files failed, and I'm ok with this. Now the question is how to proceed. Should I repair the FS first (only fixable with rebuild tree), or try to rebuild the data of the failed drive first?

Rebuild the missing disk first. If you alter the contents of any of the remaining drives, the rebuild is guaranteed to be corrupt. I hope the disks were all mounted as read only during the data recovery.

You can go either way. The wiki describes how to fix rieserfs while maintaining parity.

You are totally correct. I mistakenly read into the original post that he removed the drives from the array to copy data from the working drives.

Thanks, guys. I've rebuilt the filesystem... almost done.

I just replaced the failed disk too. After the rebuild, I got this in the main window:

 

(Last checked on 2/15/2012 10:31:32 AM, finding 7621830 errors.)

Unmenu says: Parity updated  7621830  times to address sync errors.

Should I be worried? Is my (greenballed) array protected now, at least? I'm prepared to have lost some data from before; it's from here on out that I'm concerned.

 

 

None of the drives showed any errors during the rebuild. Should I be worried. Log file attached. I have a lot of duplicate files, notifications of which have been removed from the end of the syslog..

Run a non-correcting parity check and hope for 0 errors.
