I have a 3 disk zpool doesn't want to import back after formating my OS drive and reinstalling and trying to reimport. (Went from Mint 19 to 20, imported once, OS reboot, after reboot, then won't mount again).
Was zpool at /home, have new /home on SSD, intended to mount zpool zhome to /zhome, and rsync back to /home, then create new pools with new drives, but something went tragically wrong.
$ sudo zpool import -R /zhome zhome internal error: Value too large for defined data type Aborted
To be clear, the same command worked when I first got the new OS going, there was an rsync FROM the zpool running from /zhome/user to /home/user (large one that would have taken 3 days that I forgot about) and I rebooted. After the reboot, trying to import the zpool again gave this error.
Any idea what to try?
