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

2015-01-15 Thread Yue, Cong
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

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.

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, Cong From:

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.

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?? Donny From: Yue, Cong [mailto:cong_...@alliedtelesis.com] Sent: Thursday, January 15,
