I am actually interested in hearing downsides if bcache used in front of ZFS besides obvious data implications (single copy v.s. multiple).
- geerlingguy 5y agoI documented everything in excruciating detail in this GitHub issue [1] — but in summary it was RAID5 created by mdadm (to replicate what the Drivestor 4 Pro does via ADM—it doesn't have ZFS as an option), and bcache set up on top of that with an EXT4 filesystem.
