Hey Alex,
you too, thanks for writing.
I'm on 64mb as per default for ovirt. We tried no sharding, 128mb
sharding, 64mb sharding (always with copying the disk). There was no
increase or decrease in disk speed in any way.
Besides losing HA capabilites, what other caveats?
-Chris.

Red hat also recommends a shard size of 512mb, it's actually the only
shard size they support. Also check the chunk size on the LVM thin pools
running the bricks, should be at least 2mb. Note that changing the shard
size only applies to new VM disks after the change. Changing the chunk
size requires making a new brick.
libgfapi brings a huge performance boost, in my opinion its almost a
necessity unless you have a ton of extra disk speed / network
throughput. Just be aware of the caveats.
