Hi everyone,
I am a longtime "lurker" here on Hard Forum, but now need to ask help that hasn't already been posted
I reinstalled OmniosCE/Napp-IT last year to replace my previous Omniti version, and I stupidly forgot to set up scheduled scrubs for my pools
I discovered this last week, and initiated scrubs on my pools. Unfortunately one of my very active pools, a RAIDZ2 with 8 3TB drives lost 2 drives during the scrub overnight and then a 3rd during the rebuild, leaving me with an unavailable pool.
I have imaged the 3 failed drives (using ddrescue) which all had inaccessible partition tables (bad sectors in the first 1 MB on the drive) and a small scattering (around 3MB in total) of bad sectors in other areas of the hard-drives successfully, and my plan was to insert the newly imaged drives into my system, and have them rejoin the failed pool *somehow*, so a resilver / scrub can restore integrity
The newly imaged drives have been inserted into the system and are recognized as drives, I am just not sure what I can do from here.
As the pool is offline, I can't do regular zpool maintenance commands, and I obviously need to get the new drive IDs to be recognized as belonging to the the ZFS pool somehow, which makes me speculate that I might need to do some editing / zdb magic somehow, or perhaps if there was a way to have new drives have their drive ID set to the old one they are replacing?
Any input and suggestions will be much appreciated
