ReadyNAS Pro Business Spontaneous Reboots 16779147/19770493

So, the problems persist with this ReadyNAS PRO Business. I know it can't be trusted, so I only use it for backups. I finally had time to mess with it and also needed to expand the array, so I was able to further diagnose what's going on -- in short, it's clearly not RAM and it's not hard drives -- I've put more than 20 unique combinations of drives and I can repro the problem. The only scenario that doesn't leave me with a dead array is starting with 2 new drives and expanding the array one-by-one.

Error Message or Problem: 1!!Fri Oct 26 05:26:15 CDT 2012!!root!!Volume scan failed to run properly.

Array Destroyed
SW version: RAIDiator 4.2.22
This system intermittently reboots within 2-7 hours while resyncing after replacing a drive. The error message after reboot is:

1!!Fri Oct 26 05:26:15 CDT 2012!!root!!Volume scan failed to run properly.

THE ARRAY AND ALL DATA IS LOST

Steps taken to diagnose:

- Run memory diagnostics overnight with no errors
- Replaced RAM
- Completely replaced HD with drives that have no ATA errors
- Attempted 3-drive array instead of six
- Attempted 3-drive array in slots 1-3 and also 4-6 to try to ID a backplane issue

None of these have resolved the issue.

I have also moved drives to another known good ReadyNAS Pro Business and that NAS will build the drives into an array with no problems.

The system may also occasionally reboot when it''s not resyncing a new drive, but aside from a UPS offline report coming from other NAS it''s difficult to tell when this happens or why.
