the last drive has 22 checksum errors ^^

Your disk gptid/a9595cf6-522a-11eb-a6ad-a8a1591008b1 is showing 22 checksum errors. This is typically a sign the disk will fail soon. To figure out which disk this is, run midclt call pool.query | jq, which will output JSON code. One of the blocks will have this gptid, and will state which disk (e.g., ada4) this is. Once you've located the disk, run the procedure to replace a bad disk.

While the steps to ID the disk are accurate, before jumping to "replace the disk" I would suggest "check the output of smartctl -a /dev/adaX for signs of failing hardware" and maybe "replace the cable" first, especially if it has signs of sharp bends or potential internal stress points.
