Hello,
I followed instruction at http://bcache.evilpiepirate.org/ and it cant mount...
What I'm doing wrong?


I make:

git clone -b bcache-dev http://evilpiepirate.org/git/linux-bcache.git
git clone -b dev http://evilpiepirate.org/git/bcache-tools.git

cd bcache-tools/linux-bcache/
make oldconfig
make -j6 deb-pkg
make -j6 modules_install
make -j6 install
reboot

wipefs -a /dev/sdd

Then, just run

bcacheadm format -C /dev/sdd
strace -v -o bcache_mount_strace.txt mount /dev/sdd /test_bcachefs

and it hangup....

root@bcache:~# tail bcache_mount_strace.txt
