I use glusterfs3.3.0 as KVM storage, but I have found the
performance in vm is poor.
I have the same problem as the below bug:
https://bugzilla.redhat.com/show_bug.cgi?id=842254
the I/O performance is < 1% of my hardwares capability.
Hopefully work on buffering and other tuning will fix this ? Or maybe
the work mentioned getting qemu talking directly to gluster will fix this?
I replied with my phone, but didn't notice that I replied directly. For
the benefit of others:
Or change your perspective. Do you NEED to write to the VM image?
I write to fuse mounted GlusterFS volumes from within my VMs. The VM
image is just for the OS and application. With the data on a GlusterFS
volume, I get the normal fuse client performance from within my VM.
