How can I mount a single RAID 1 disk/partition as ext3?












6















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.

  • any idea how to do this on a Mac? I'll be needing an Ext4 driver for sure, but is there anything else that need to do to mount the formerly RAID-1 drive?

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

  • You might need to launch mdadm --run /dev/md# to start a partially assembled array

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.

    You don't have to force anything. Just mount the md device: "mount /dev/md1 /mnt/myfolder". The degraded array will run without any problem. But nothing garantee the Symbology use a standard Linux RAID.

  • Ext[234] has no "force" mount option, so this answer is nonsense.
