And yeah, I can go to that length. I have drives that can take both, I fortunately got 2 4tb disks... One is a windows install but after backing up the data on it to my spare smaller disks and ensuring I have all my keys for all else done I can duplicate the primary zfs containing disk too
I'm sure I am going to figure this out.
It reminds me I was going to run vanilla, which is a layered snapshot driven Linux. It would have been easy to run it on the machine that had Bitcoin core, and this problem would have been much easier to recover from... It was literally because I stupidly used zfs on it
Never ever zfs. It is the Wayland of storage, fucking shit.
