Actually, I just tested and mounting multile devices directly
_does_ work - you
just pass a colon separated list of devices to mount:
mount -t bcache /dev/sdb:/dev/sdc /mnt
I could have sworn this was broken, but worked just now...
This works for me. Thanks for the feedback!
For any others wanting to walk this path in the near future, here's
the
entire sequence that is working for me (as of kernel and tools pulled
on
2016-05-13):
bcache format --tier 0 --bucket=512k --cache_mode=writeback \
-C /dev/nvme0n1 \
--tier 1 -C /dev/sdd1
echo /dev/sdd1 > /sys/fs/bcache/register
echo /dev/nvme0n1 > /sys/fs/bcache/register
You should be able to remove these steps, I think?
mount -t bcache /dev/nvme0n1:/dev/sdd1 /mnt/whatever
If you've pre-registered, you should be able to just
mount -t bcache /dev/nvme0n1 /mnt/whatever
or, entirely equivalently:
mount -t bcache /dev/sdd1 /mnt/whatever
