My FreeBSD 5.2.1-RELEASE box is being hosted remotely.

I switched from RH to FreeBSD. All my web files etc are on the second
hdd in an ext2fs partition.

I have read numerous guides, manuals, etc, but have not found a
solution for my problem.

I have compiled my kernel with the "option ext2fs".

Here is what happens if i try to mount the other hdd:
# mount_ext2fs /dev/ad2s2 /mnt
mount_ext2fs: /dev/ad2s2: Invalid argument

# mount -t ext2fs /dev/ad2s2 /mnt
ext2fs: /dev/ad2s2: Invalid argument

Here is all the information I could gather about the disks:

While entering fdisk I did get a message saying the geometry of my
disk wasn't correct, and it would pick a better one, I didn't write
the "new" geometry if fear of messing something up. Could this be part
of the problem?

Also I read that some versions of linux use "Magic Clusters" to create
more hdd space on larger drives, this also may be part of the problem.

Please keep in mind I don't have physical access to the box (I do
however have full root access via ssh), and only have access to
FreeBSD.



What I would like to get is:
Fairly simple step by step solution for mounting an getting the files
off the 2nd ext2fs drive. Mounting it in read only mode would work
fine. I'll be happy to disclose any other information about what
libraries/binaries I have installed.
Thanks,

Try shotgun approach:

# mount_ext2fs /dev/ad2sN /mnt

with N = 1 to 7

Try appending letters too:

# mount_ext2fs /dev/ad2sNL /mnt

with L = a, b, c, etc.

(I might try first /dev/ads2a)

Thanks for the tip, I've hit it with a few shotgun shells as you
suggested, but each time I receive:
mount_ext2fs: /dev/ad2sN: No such file or directory

I don't think i'm doing anything wrong, perhaps it's my system.

First, you're certain /mnt exists, yes?

Then, you tried all permutations of /dev/ad2sNL,

with N = 1, 2, 3...7 and

L = a, b, c...f

i.e. /dev/ad2s2a
     /dev/ad2s2b
     etc.
     /dev/ad2s1a
     /dev/ad2s1b
     etc.

?

Absent any luck with the above, I'd post to one of the freebsd mailing
lists or newsgroups.

Yes, that is what I did. Yes /mnt exists and is chmod'd to 777.
Thank you for taking time to reply and sugest an alternative. :)

ext2 should be already compiled into the 5.2.1 kernel, and if it isn't
it should still be a module so that really should be an issue.

mkdir /linux
mkdir /linux2
mount -t ext2 /dev/ad2s1 /linux
mount -t ext2 /dev/ad2s2 /linux2
you apparently also have another linux partition on /dev/ad2s1

Thanks for the coments. My hosting provider gave up and ended up
sending my the hdd. I've since grabbed the files needed.

Thanks for the help!
