[Solved] Unable to mount Buffalo LinkStation array

[Sevideous]

So I have searched the boards and was able to find the post below but had concerns using the mdadm not knowing what I am actually doing. I am looking to copy my data off of a drive that was mirrored in a Buffalo Linkstation and I am getting the unable to mount location error.

Thanks for your help.

I don't know about the LinkStation, but I mount my two TeraStations using the CIFS network file system to a mount point on my Linux box using the command:

mount -t cifs //tstation-network-address/directory local-mount-point -o user=tstation-userid,password=tstation-passwd,uid=local-name,gid=local-group

Sorry my topic was misleading. I had the mirror setup on the linkstation but one of the drives died. I pulled the working drive out of the linkstation and I now have that working drive plugged into my Ubuntu system and need to recover the data. Ubuntu recognizes that there was array setup on this drive so I am not sure how to access the data on the single drive because of the unable to mount error.
You can also disregard the W95 FAT32 device as that is my thumb drive I was attempting to copy the data to.

Thank you.

In any case, Ubuntu should display its details in output of fdisk. Are you sure Ubuntu has detected it correctly? Isn't /dev/sda internal Hard disk having Ubuntu?

[Sevideous]

The details of the fdisk in the original post are from one of the drives I pulled out of the linkstation. I am currently booting Ubuntu from a CD Rom.

[devils casper]

In that case, there shouldn't be any problem in mounting partition.
Try to mount /dev/sda6 in Terminal :

mkdir part6
sudo mount /dev/sda6  part6

In case it doesn't work, specify filesystem too.

sudo -t ext3  /dev/sda6  part6
cd part6
ls

Post exact error message here, if any.

[Rubberman]

I think that the Buffalo devices use xfs as their native file system which may not be configured into the Ubuntu CD-ROM boot/kernel image.

[Sevideous]

ubuntu@ubuntu:~$ mkdir part6
ubuntu@ubuntu:~$ sudo mount /dev/sda6 part6
mount: unknown filesystem type 'linux_raid_member'

I did not specify the filesystem as Rubberman stated they do use xfs.

Are you able to point me in the right direction in obtaining a version that does include xfs?

[devils casper]

I did not specify the filesystem as Rubberman stated they do use xfs.

I would suggest you to try ext3 once.


Have you tried Graphical Interface of mount command? I am sure about its path in Ubuntu LiveCD. Check it in System - Disk and Network File systems - Add Mount - Filesystem -- and select RAID device.

Thank you all for your help this has been great! I tried Knoppix and Parted Magic and just could not get it recognized properly.
I found a spare linkstation and have it limping along on 1 drive.(its shuts down every 5 minutes)
I have 60GB to copy so it is taking me a couple of hours to get it.

Thanks again.
