Subjectflashcache over md or lvm2?
Hello,

I've seen some problems with flashcache and md/lvm2. When I create
RAID0 with either md or lvm2 and use it as a flashcache
(https://github.com/facebook/flashcache) writeback cache, I noticed
through blktrace that some bio only hit one SSD but not the other.
iostat also confirmed the situation. So I'm wondering if the setup is
even possible?

Thanks,
