I need to copy data from a single HD, which used to be part of a Linux RAID 1. I've googled around, but can't find any clue how to mount partitions from this single HD.
Background: The HD comes from a linux based NAS box Synology DS207+. The NAS uses ext3 as filesystem. Both NAS disks are fine, but the other NAS hardware is dead and not worth repairing or replacing.
An important step is to have mdadm scan for the disk prior to attempting to mount anything:
mdadm --detail --scan
I can't recall from memory but the --assemble flag may be necessary but try the above first then try mounting via:
mount /dev/md# /path/to/mount
When you only have a single part of a Raid array, it is in an incomplete state and for safety reasons, you basically have to force mount it.
There are many linux distributions, for me, in Ubuntu, I used:
mkdir /mnt/tempdisk
sudo mount /dev/sda3 /mnt/tempdisk -o force
(replace sda3 with the hard drive)
if a *nix expert wants to down vote me, I will delete my answer as it has been a few years since I did this, and I followed a guide at the time.
