I was to use ssd to cache my mdadm-raid5 + lvm storage.
Not that sure that layering MDADM on top of DM/LVM2 is always a
good idea, I tend to prefer to keep things simple.
Is that what the OP is doing? I don't think putting raid on top of lvm
is a good idea, which is why I'm putting lvm on top of raid.
Whatever, I guess you're better putting the cache on the bottom layer,
just above the actual hardware. In my case, that would be caching the raid.
