Same experience here. Gluster ‘failover’ time was an issue for as well (rebooting one of the Gluster nodes caused unacceptable locking/timeout for a period of time). Ceph has worked well for us for both nova-ephemeral and cinder volume as well as Glance.
Just make sure you stay well ahead of running low on disk space! You never want to run low on a Ceph cluster because it will write lock until you add more disk/OSDs<br class="">

<div class="">We tested GlusterFS a few years ago and the latency was high, poors IOPs and every node with a high cpu usage, well that was a few years ago.</div>

<div class="">We ended up after lot of tests using fio with Ceph cluster, so my advice it's use Ceph Cluster without doubts </div>
