    [SOLVED] Previously used zfs drives are not available

    Yeah, that is what it looks like. If you feel comfortable, do a double or even tripple check on drive I'd, I. E. Sda, sdb etc and run the DD on each and see if it solves the problem. Pick 2 , run DD on then, than try creating a mirror zfs. If works break it and do same for the rest. Slow and...

    Do this drives show up differently in lsblk command after the cleanup? The re-creating gpt table always worked for me. The only other thing I did ones is zerro out the disk with dd. dd if=/dev/zero of=/dev/hdX This removes everything but is wery long process.

    ZFS Pool is degrading alternately between two disks

    Well before anything else check your cables. A loose power or sas/sata cable to the disks will do that. If not , and you are sure the disks are ok, it may be your PSU.

    ZFS mirrored rpool disk ID changed, cannot zpool replace

    It says right there. There is a problem with your drive. You need to replace the physical SSD drive and then replace it in the pool. You are trying to add original SSD back when it fails.. Edit: sorry, mistook your new I'd for existing one. Disreguard this post please.

    Ok, I am marking this as solved. Turned out it was my bios that is totally screwed up. It not allows more than 2 boot disks, really? A server MB only allows 2 boot devices, but I had to fiddle with settings for like 3 hours untill I found where and what need to be set for it to work.
