Sure can
http://www.gluster.org/community/documentation/index.php/GlusterFS_iSCSI
As for tuning, I don't have enough information about my own system to even
say. I know that there are tuning options that you have with glusterFS, and
you will have to see what works best for your deployment.

It is just the default configuration. What is your advice for the tuning of
I/O performance?
For Gluster FS, actually I used Xenserver currently. I justed mounted the
gluster as a NFS to XenHost to be used as a SR. Is there any way to use
GlusterFS as a iscsi target ?
Thanks,

I see.
So have you done any tuning for IO performance or are the configs straight
out of the box. You also said you mounted the volume to a vm. Did you mount
it as gluster or use the built in NFS??

I am using iometer (http://www.iometer.org/) to test the IOPS from one of
the vm.
As for IOPS is more trying to test the performance of block, rather than
real file transfer.
In my environment, I am using 10Gbe to make two gluster nodes be replicated.
And I mount it to vm as a volume. I tested the performance both for SAS and
SSD.
This is my current result with iometer.

The issue for GlusterFS I found is
- It can not retain the nature of SSD and SAS, such as SAS is
strong for sequential access. SSD is strong for random access.
- In some case, especially for SSD, the performance is pretty bad.
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?

Subject: [ovirt-users] Performance issue for GlusterFS as the block storage

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
worse performance than normal NFS.
Should I use iscsi+drbd for the block storage for VMs.
Can somebody give some advice for this?
Thanks,
Cong
