Subject: Is It Hopeless?
Date: Sun, 26 Dec 2010 10:19:55 -0800 [thread overview]
Message-ID: <201012261019.56481.CACook@quantum-sci.com> (raw)
I went in to turn on my home theater system today, and found a blank screen. I rebooted and it would not mount /home, which is a 4TB RAID10 array with every movie and show I've recorded over the past two years. I try to mount it manually, and "wrong fs or bad superblock". The array is getting set up fine, but the filesystem seems to be destroyed.
Unbelievable. This isn't supposed to happen. It happened once before when I wasn't using RAID, but that was the BTRFS filesystem and I blamed it for being pre-release. But now it's RAID10 with JFS.
The only sign of trouble:
