I dug an old FreeBSD (4.4 BSD) machine out of my attic the other day -- it has a pair of UFS disks in there and they've been mirrored in software. Embarrassingly, I no longer have the root or any other password on that machine -- which means that I can't get to some files I'd like to. Is it possible to mount one of the partitions from half the UFS mirror onto one of my Debian machines? I've tried

mount -r -t ufs -o ufstype=44bsd /dev/sda7 /media/usbdrive

Yes, the drive is currently mounted in an external enclosure with USB connectivity.

The error I get from executing the above is "ufs_read_super: bad magic number". There's no more help in dmesg, kern.log, etc.

I'm running Debian etch, kernel 2.6.21.5

I know this is a pretty esoteric problem; any takers? Thanks in advance.

Usually software raid does not translate from one OS to another.

I'm not trying to recreate the mirror itself, only pull data from one side of the mirror (if I understand your meaning.) I figure that it's all there -- it's just that the disk might have some metadata on it getting in the way.

The software raid part has to be functional(readable) in order to get the data off the drive. Which takes us right back to my original statement.
