Apparently, it was a battery backup unit that went bad is what I last heard.
I have 4 servers on that same unit. One cost me the whiole morning to repair.
I am not sure that it is even a GNAX problem. Which server was down 5 hours?

One big problem is that cpanel uses the ext3 filesystem instead of XFS or some other high reliability filesystem.

Depending on the situation, some of my servers have taken HOURS to come back on line - think back powering off your PC by accident and DOS or windows running scandisk for a week!

So with many linux file systems, if power is unexpectedly lost and it detects invalid dir entries, it runs fsck at startup to rebuild the filesystem and check for errors.
