Replace original removed HD after failed disk upgrade?
Hi, We have a ReadyNAS Duo which had 2 x Seagate 500GB HDs set up as a redundant RAID disk with 500GB available storage. It was becoming full, so I checked the hard disk compatibility list and orde...
Do you have a backup? If not, you should make one before you go any further.
If you removed disk 1, you could power down the NAS, put disk 1 back into the NAS, and remove disk 2. Then power up the NAS. It should boot to a non-redundant state (and holding the information when the drive was removed). Hot-inserting disk 2 would then resync the duo.
If you removed disk 2 it might be more difficult (it shouldn't be, but there have been several postings from folks who've had trouble booting up with only disk 2 installed). Though the protection mode is raid-1, the disks aren't precisely the same. Disk-2 has no partition info on the data partition for one thing.
Since expansion didn't complete, you could possible hot-insert disk 1 (trusting it to resync to disk 2). I wouldn't do that w/o having a separate backup.
