Tell me about the JFS partition, I assume that it doesn't have anything on it when you copy these dozen files onto it. Where do the files get copied to? Do they all go to the root sub dir or are sub directories created during the copy, if so how many sub directories are created. I haven't been able to re-create this one and any details you could provide could be helpful. > When the machine rebooted, it had to fsck the ext2 > partitions I couldn't unmount (naturally), but I expected it to > be able to mount the jfs partition (after transparently replaying > the journal?).
