I now have the following stack:
btrfs on LUKS on LVM on bcache
The VG contains two bcache PVs with backing devices on different
spinning disks, and a shared cache device on SSD. I'm using Kernel 4.3.
I'm super happy with the performance, boot times increased from 1:30
minutes to X11 and 2:00 to Firefox roughly 0:10 to X11 and 0:30 to
Firefox.
Time will tell if it also keeps my data intact, but I hope btrfs would
at least detect any corruption.
Best,
-Nikolaus
