ah. I see from dmesg
[ 8872.792317] bcache: bch_cached_dev_attach() Couldn't attach sdb1:
block size less than set's block size
[ 8872.792323] bcache: __cached_dev_store() Can't attach
b43b13cf-32b1-4e5a-af7d-27b6d246662d
: cache set not found
but maybe warn in the manual/wiki

Hi
Sorry to bug you (pun intended)
I get this

>/sys/block/bcache0/bcache/attach
-bash: echo: write error: No such file or directory

One unusual thing I did was to set the cache device block size
differently/seperately from the backing device. but dont see mention of
such a difference in the manual or online
