Hello,

on of the disks in an encrypted pool failed and we initiated a disk replacement.
Unfortunately the technician selected the wrong disk to replace.
this is what happened:
- the faulty disk da1 was taken offline in the webui
- the faulty da1 hardware was replaced with a new disk
- now da0 was wrongly logically replaced with da1
- da0 was not faulty
-> now we have two non-functional disks in the pool
- we tried to replace one of the two disks with the now "unused" da0, this did not work (even with the force option, as there was zfs information found on the disk, which makes sense)
- we tried to wipe da0 to get rid of the old remnants, but this resulted in a dd error.

What can we do to geht this pool into a healty state again?

Thank you in advance for your help!

Does replacing the 2 problematic disks with new disks resolve the issue?
