Hi
I have one question about whether GlusterFS is the suitable solution to be =
used as the block storage for VMs.
The failure tolerant and scalability is good for GlusterFS, but in my test,=
it seems the iops is pretty bad. In some blog, it said, it is even with wo=
rse performance than normal NFS.
Should I use iscsi+drbd for the block storage for VMs.
Can somebody give some advice for this?
Thanks,
Cong

Do you have any metrics to give an idea of the difference. I am using NFS
right now, and I am migrating to Gluster. I have the gluster system up, and
I see that it seems to provision disks faster than my NFS. I haven't used
any real measurement tools to get actual metrics, this is all perceived.
Do you have an operational gluster?
Do what are you using right now?
