Help replacing failed drive?
« on: May 13, 2014, 08:17:09 pm »
Hi,
I have four 2TB drives in my pool, 3 DRUs and 1 PPU. One of the DRUs has failed, so I ordered a new drive, replaced the old drive with it, initiated formatted and assigned a drive letter in Windows, gave it the same drive letter and name as the prev failed drive, and then used the "Restore" button. The restore says it completed:
Code: [Select]
[2014-05-13 19:54:38,458] INFO : There are no files to recover! Exiting...
[2014-05-13 19:54:38,458] INFO : [restore] completed at: Tue May 13 19:54:38 EDT 2014

So, I did this following the directions from here and here. No joy.

Nothing seems to have happened. There are no files on the new drive, and it does not appear to be added to the pool.

What should I do to bring the new drive into the pool and get it 'restored' into the same role as the old drive?

Thanks,
Ari

You have a Cruise Control configuration. What are you doing following a guide for an Expert mode configuration?

OK, I've performed the steps in the reply above. It appears to put the drive into the pool, but the new drive is empty (checked by giving it back its drive letter and viewing in file explorer).
The process finishes quickly giving me this:


Here's the log:

What do I need to do? Run an update to re-do the parity? Other?
Thanks,
Ari

If the restore says there is nothing to recover, then the disk might have been blank. Are you able to validate whether the disk had files or not?

Brilliant! I hooked up the failed drive to another computer and found it contained no files...  :-[
Thanks again, and glad the drive replacement process seems to have worked. (Hopefully it would have even worked with a non-empty drive  ;) )

Next, Updates perform successfully on the pool with the newly replaced drive, but Verify always fails (even if I turn off the pool, run update, then run verify). I've attached the log output from the most recent verify.

How do I go about fixing this?

It looks like I had another drive about to fail, in addition to the actually failed drive. So I've replaced both, now update then verify completes without errors.
Thanks as always
