Hi!
Please advise me how should I do the easier data migration from a HDD RAID1 array (6TB - which 3.3TB are occupied before some cleaning which can get the loading to 2-2.5TB).
I have an Odroid HC4 (Debian from HK installed and OMV7). Booting from an sd card, data is kept on that RAID1 HDD array.
I want to change the data destination from HDD to SSD going to a 4TB SSD for docker containers &data and a 2TB for plex, system backups, docker backups.
The SBC has one usb2.0 port so the usb-backup path could be a little painful when to migrate 3TB of data.
What should be the easier way to keep the SO in function and migrate the data without too much reconfigs? I mean preserving permissions, UUIDS, docker configs etc.
I read a little bit about and Rsync should be the best approach?
As steps I got this:
- degrading the array to one HDD and resync the data to the new 4TB SSD
- remove the other HDD data disk
- setup the new UUIDs/paths/symlinks for the SSD or they could be preserved by Rsync?
I know it sounds weird but this modification bares the wife factor (lately the drives are getting noisy - the Seagate Ironwolfs I have since OMV5 - don’t support acoustic management or spindown) and I stopped been a data hoarder. So I want something almost deadly silent and keep the electricity bills down
- joking - this SBC with HDDs doesn’t consume much.
