My God, it didn't have the command fsck.jfs, so I reinstalled jfsutils. Now the array mounts.
I don't understand it. I thought the JFS driver is in the kernel?

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.
