Of the 36 original disks, you have 34.  You have one incomplete

If you have any access to the two "dead" drives, there might be
a slight chance. Since they were likely kicked out due to timeout
mismatch, not a complete failure, this could be possible.

Otherwise, you are utterly screwed.  Sorry.

The disks are dead. I already tried different boards but that did not help.

What would happen if i recreate the array with —assume-clean ? Would i be able to start the array? Can I mark disks as clean? I actually have one failed disks, one nearly recovered disk and one that has been copied by 2/3 ...
