ReadyNAS 626 Status Is "Degraded" After Successful Resync
Just added a new HDD and am seeing this message after the resync: Dec 13, 2022 06:33:28 AM
Volume: The resync operation finished on volume data. However, the volume is still degraded. Any i...
You can do it manually via SSH: Reducing-RAID-size-removing-drives-WITHOUT-DATA-LOSS-is-possible . You'd need to "remove" the missing drive. But given your multiple-layer volume, it's very tricky and there will be a lot of re-syncs, which put the data more at risk. You are probably better off waiting for the replacement drive.
Thanks, Sandshark and StephenB for all your input so far, and thanks too for your patience. I feel like some of this is basic ReadyNAS 101 info, but I haven't ever had to resort to it before and am super afraid of data loss.
I have a spare ReadyNAS 314 that I've been using for a long time as a share-based backup. Each of the eight shares on my 626 has its own daily backup job. The 314 initiates those jobs via rsync.
For peace of mind, what I'd like to do is fully clone my 626 to the 314 in order to preserve every byte of data as is, including snapshots. (Long story short, I've noticed some music files that are preserved in the snapshots but missing from the active share. At some point when I have several hours to spare, I'll have to compare the share vs. the snapshot and restore the missing files.)
Cloning would save me the worry of losing any data while the volume is degraded, and it also might allow me (I think?!) to wipe the 626 completely and start fresh to avoid the fragmentation that has occurred as I've expanded my NAS array with larger HDDs over the years.
A) Is the cloning strategy that I've proposed a good idea and B) if so, what method would you recommend to carry it out?
