Preserving data on a ext4 HDD

Preserving data on a ext4 HDD

Postby ivan » Wed May 13, 2020 4:41 am

Hi,

I have an AS5202T and like to add an ext4 formatted HDD with about 4TB of data without wiping it.
How can this be done?
I have a backup but don't want to unnecessarily shuffle all that data around again.
Thank you.

Kind regards
ivan

2 options:
  • Put this disk to an USB external box, then connect to NAS.
  • Put this disk to an internal bay. You can use "mount" command manually (by means of ssh) to mount your data. No ADM UI available.

Thanks for your reply.

Actually I tried to mount it via ssh before but failed to do so.
Now I found out why that was the case: the HDD was somehow configured as RAID.
I have no clue why though as the HDD was setup with the NAS and I most certainly chose JBOD (the other drive is a 480 GB SSD...).
Then I reset the NAS because I couldn't access it with ssh anymore.

After running `mdadm --assemble --run /dev/md2 /dev/sdb4` I could finally mount it.

But I still can't manage it with the web-GUI.
How can I do that?

OK, your disk is actually the one that configured by ADM. ADM configure disk as RAID, no matter it's single, JBOD...

No, you cannot manage it within ADM UI (because you did it by yourself, rather than ADM).
