I apologize if this has been discussed before, I did try a search, but couldn't find an exactly similar situation. I had four (4) 8 TB WD drives that all experienced what I believe to be a power spike / failure. No disks would spin up when power was applied. I've since sent them to a repair shop to be looked at and only two (2) of the drives are able to be recovered. My setup included three (3) drives for data with one (1) in parity. With two (2) drives failing, I believe I have a total loss of data at this point. I'm trying to come to grips with this, as it truly is what it is, 2020 has struck... This configuration also included a SSD cache drive which still shows as available / good in unRAID and in BIOS. I have purchased one (1) new 2TB drive for now, simply to get things back operational (I was utilizing, HomeAssistant, MQTT, Plex, Unifi, etc dockers and would prefer them to be working sooner than later).
Also, I'm hopeful, but honestly cannot remember if I had it setup to backup my appdata folder to the cache drive or the array or both. The more I think about it, I think it was only the array, which sucks for obvious reasons... I haven't re-started the array to check, because it is showing all of the drive failures and I didn't want to go down the wrong path.
Is there any reason to wait until the two (2) drives are recovered to do anything with the current unRAID array setup?
I've come to grips with the loss of data and have a better plan moving forward, but would really love some coaching as to the 'easiest' way to get things back to 'normal'. Ideally, I'm able to start a new array and 'apply' my appdata from the existing cache drive to the new 2TB drive?
Thank you all in advance!
