I could make it work, thanks to Pavel Goran from the bcache mailing list, see the details below: Le 28/05/2015 11:09, Pavel Goran wrote :

jdd answer: 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! jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
