Hi Mauricio,
according to my Bash history, I used the following two commands to create the Bcache device:
make-bcache -B -b 524288 -w 524288 -o 8192 /dev/vg0/vg2-backend make-bcache -C -b 4194304 -w 4096 -o 8192 /dev/vg1/vg2-cache
I think the reason why I used this block size was that the MD RAID device backing vg0 uses a stripe size of 512K and I wanted to ensure that everything is neatly aligned.
Best regards, Sebastian
