I had a pair of Crucial MX500 SSDs in RAID1 for my cache pool and had noticed the logs filling up with IO errors. Thinking these errors were related to the previously reported BTRFS problems with the Crucial firmware, I planned to replace the cache drives with another brand.
In the interim, I applied the update from 6.11.3 to 6.11.5 and rebooted. Upon rebooting, the array refused to start, complaining the cache drives were unmountable. I foolishly tried removing and re-adding the drives to the pool but applied them in the wrong position and lost the MBRs - cache pool was a total loss.
In any case, I am now trying to rebuild with my replacement cache drive installed. I precleared it, formatted, and added to the cache pool, and click Start array. The array does not start, though. The parity check begins but the array stays offline. I tried letting the parity check complete, thinking maybe the array would start after the check is completed, but the parity check just hangs at 29.1% complete. I let it sit at that level of completion for about an hour but no further progress was had.
I've rebooted again and am still getting the same behavior. Parity check starts but array does not. I am also getting a message about a stale configuration. I'm not sure where to go from here.
