got it!
echo 1 > /sys/block/sda/sda3/bcache/running
was the key :-)! thanks!
the manual says:
"make-bcache has the ability to format multiple devices at the same time"
but then:
To get started:
mkfs.ext4 /dev/bcache0
so the word "format" is not used always with the same meaning (for me,
formatting is creating a file system).
gladfully, make-bcache do *not* format the partition :-)
What I did:
* install a new system elsewhere (same distro I used with bcache).
kernel 3.16.7
install bcache-tools
make-bcache -B /dev/sda8 (the old bcache backing)
tried to find /sys/block/sda/bcache, but it do not exist. Your example
made me think the manual lacked a level, it have to be
sys/block/sda/sda8/bcache
echo 1 > /sys/block/sda/sda3/bcache/running
and then /dev/bcache0 shows up!
mount /dev/bcache0 /mnt allows me to access the files on the partition
so good, thanks!
