Hi,
I have just got a pair of larger hdds and want to copy the data from the old disks to the new. Old setup was 250gb raid1, new setup 1tb raid1. I pulled the disks, did a factory reset, installed the new drives, formatted as raid1 via the web interface. Installed ffp, telnet, ssh and ufs. Connected one of the pulled drives to a desktop and booted from a ubuntu live cd. I can see the pulled disk in ubuntu in gnome partition editor and System -> Disks. But I am having problems mounting it - there is no mention of sda2 (the partition with the data I want to copy) in /etc/fstab /etc/mtab. fdisk -l shows /dev/sda has 2 paritions - linux swap and linux. But it also mentions /dev/md0 - which is what the raid1 array is referred to by the dns-323. and it says "Disk /dev/md0 doesn't contain a valid partition table"
So, how can I mount (r/o) the pulled drive? When I try "mount -r /dev/sda2" I get "mount: can't find /dev/sda2 in /etc/fstab or /etc/mtab"
thanks

Do you happen to have a USB enclosure? If you do, plug one disk into it and plug it into the USB port on the DNS. Using fun_plug and the USB disk module, you can mount and transfer the data natively onth DNS.

mkdir /mnt/dnsdisk
mount -r /dev/sdc2 /mnt/dnsdisk
You data is in /mnt/dnsdisk

Hi,
thanks for these. I don't have a usb enclosure. I got it working with mount -t ext2 -r /dev/sda2 /home/me/Desktop/old after noticing that when you don't specify a file type you get the complaint along the line of "fs not recognised: linux_raid_member"

Also, to be pedantic (and hopefully help future readers of this thread), mount normally takes source (device) and destination (directory/mountpoint) arguments - if you use just one or the other, it assumes you're referring to a situation already configured in /etc/fstab and goes to look for the rest of the info there. To mount an ad-hoc device, you must use both, as in:
home> mkdir ~/temp
home> mount -t ext2 /dev/sda1 ~/temp

Cool, very useful to know.

Yes, the mount command I gave assumed that there was already a directory called "/home/Desktop/old"
