First, you may want to check if there is any dirty data in the cache, by
executing:
cat /sys/block/bcache0/bcache/state
cat /sys/block/bcache1/bcache/state
If these return "clean", then you should be good to detach the cache.
I get "no cache", not sure why:
[jdg@tiare ~]$ cat /sys/block/bcache{0,1}/bcache/state
no cache
no cache
Here are the kernel logs concerning bcache:
[jdg@tiare ~]$ dmesg | grep bcache
[ 9.217610] bcache: bch_journal_replay() journal replay done, 0 keys

devid 1 transid 29647859 /dev/bcache0 scanned by systemd-udevd (290)
That was after rebooting, and no trying to mount the broken Btrfs RAID1.
So, should I detach the cache?
Thanks for your assistance Pavel,
Best regards,
