Hi, I have a failing SSD I need to replace so I added another disk to my array, but didn't get around to removing the faulty one. A few days later I went to remove the faulty one and there were no more errors, I presume because the bad portion of the SSD was now not in use. Because I didn't know what disk to remove (2 are identical) I removed the new one in the hope to trigger the error with the old one so I could note it's serial number. This was successful, but btrfs is claiming the error is on the disk that I removed. I presume this is a bug? This is the command I used to remove the new disks: btrfs dev del /dev/sda1 /dev/sdb1 /media/fast/
I note in dmesg there was no mention of /dev/sda1 'Fast' is the filesystem in question. ..
