Steps to reproduce: get the bcache-tools package... I used, http://debian.spnet.net/debian/pool/main/b/bcache-tools/bcache-tools_1.0.7-1_amd64.deb Build from source if you like
make-bcache -B /dev/cciss/c0d0p2 -C /dev/cciss/c0d1p3 reboot echo writeback > /sys/block/bcache0/bcache/cache_mode echo 32M > /sys/block/bcache0/bcache/sequential_cutoff mkfs.ext4 /dev/bcache0 ; mount /dev/bcache0 /mnt wait a bit and then in dmesg or console you should see. Aditionaly the load average is 2, for no good reason. cat /proc/loadavg 2.21 2.06 1.97 1/127 3224 Found the same bug in Ubuntu: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1357295 This machine is a dev box, so we can try different things on it, let me know if I can help further. *Ursan Bogdan* *Administrator ITPhoenix Media*
