Hi Reartes,

I tested F20 on a physical host with a vertex3 ssd.
But it was not a requested test case, i re-used a md raid0 with a 6gb
partition of the ssd.
The file-system was setup as a storage pool for virt-manager.
I did not experience any issues, i installed 2 F20 guest at the same time.
I even rebooted many times and it survived several kernel updates.
I did not test a power-loss scenario. I has been working ok since a
couple of days.
I also did the non lvm tests on guest, without any issue.
Thanks for your feedback, glad to hear it works well for you.
The only thing that i can recall as strange is the fact that bcache
seems to not to use discard/trim for some reason.
discard/trim can be enabled, see:
http://evilpiepirate.org/git/linux-bcache.git/tree/Documentation/bcache.txt?h=bcache-dev#n126
There's also an explanation in the document why it isn't enabled by default:
"|Defaults to off, since SATA TRIM is an unqueued command (and thus slow)."
