Re: RAID 6 Failure follow up

[Ryan Wagoner <rswagoner@gmail.com>]

Boot up a CentOS 5 LiveCD. It should detect your arrays and try
running smartctl. From my experience with different distros I have
found that Red Hat spends a good amount of time making sure enterprise
hardware is stable on their system. Ubuntu seems to focus more on
desktops.
