I'm looking to see if I can get some validation or confirmation of my plan relevant to the setup and situation I have below.
Current Setup:
- SnapRAID pool
- 3x 4TB Data Disks
- 1x 4TB Parity Disk
- MergerFS
- /storage with multiple sub-folders and content
- SMART Test
- Running every Wednesday night (corrected to Wed)
- Recent report flagged 3 bad sectors, then within the last 3 days or so bumped up to 7 bad sectors
- Already filed RMA with WD and new drive is here
Plan:
- Install new physical disk alongside others
- Reboot into CloneDrive
- Clone current failing disk to new disk
- Shutdown, and remove failing drive
- Startup and name disk same as failed disk
- Add new (replacement) disk to SnapRAID/MergerFS pools as same name
Does this logically make sense, and actually make sense to achieve what I'd like to? It seems cloning will have the quickest/easiest processing to get this done, and avoid stupid snafus by me on the command line with permissions and other potential problems. My only main concern really is ensuring SnapRAID doesn't have problems continuing on like nothing happened, MergerFS volume /storage isn't affected, and that the clone with bad sectors on the drive doesn't cause some other type of copied issue.
If I lost the 7 bad sectors, I'd be ok with it honestly. I'd rather salvage the rest of the data, then be able to do a SnapRAID Fix operation.
