I noticed in the UnRAID 6 documentation a section explaining "swap-disable", which seems like what I need for my situation. But I couldn't find this section in the UnRAID 6.2 documentation.
Is swap-disable still supported? Does it work the same way as documented in the older docs?
My situation:
My array including parity is three 1.5 TB drives that are several years old. One data disk is showing disabled. I suspect it's dead (been making unusual noises for a couple of weeks, waiting for a SMART self-test to finish now). Assuming it requires replacement, I would like to take this opportunity to start upgrading the size of my drives. One reason is that to replace this drive with another 1.5 TB drive is now relatively expensive, compared with newer drives that are double or larger the capacity.
My understanding is that swap-disable will allow me to buy a larger drive, use it as the new parity, and use the existing parity as the "new" data disk. Somehow UnRAID recognizes this scenario, and rebuilds or copies the parity to the new parity disk, and then rebuilds the data on the "new" data disk (former parity).
it looks like it will "just work" but I wanted to be sure before I move forward.
I attached my diagnostics zip file in case it offers any clues. TIA for any help (or reassurances!)
