Hi,
Not sure if I'm in the right place to post this, came here because I found pointers of other people that found help here!
I have 2 disks that were in a SHR config in a synology 2 disk station. One day I got an error with one of the harddrives. Data had become read only.
Searched and found explanation to recover or copy data using ubuntu.
Using ubuntu 16.05 LTS.
2 disks are /dev/sdc and /dev/sdd.
info /dev/sdc
Code:
erwin@ubuntu-1:~$ sudo mdadm -E /dev/sdc/dev/sdc:
Code:

Trying to assemble throws superblock error:
Code:
erwin@ubuntu-1:~$ sudo mdadm --assemble /dev/md0 /dev/sdc1 /dev/sdd1mdadm: superblock on /dev/sdd1 doesn't match others - assembly aborted
Can anyone point me to how to make my data visible and retrievable?
Thanks for helping out!
