| |
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, -Bergwolf
