Is there any way to recover from this situation without a reboot?
I found that there was still a dm-crypt device active on top of the
bcache device.
I did this:
$ sudo cryptsetup remove backup1
Device /dev/bcache1 does not exist or access denied.
Device /dev/bcache1 does not exist or access denied.
Device /dev/bcache1 does not exist or access denied.
$ echo $?
0
After that, power cycling the backing device allowed it to come back as
/dev/sdi and auto-register with bcache.
