but if you are comfortable with it go ahead as I don't think this will be the

Joe,
I don't think we have to accept this as this is not acceptable thing. I have
seen countless people complaining about this problem for a while and seems no

The thing about the ramdisk although might help, looks more a chewing gun. I

Well, it actually says it is a limitation of the Infiniband driver so nothing

Using the Gluster client it should in theory access the file(s) directly from

I think this discussion probably came up here already but I couldn't find much
on the archives. Would you able to comment or correct whatever might look wrong.
What options people think is more adequate to use with Gluster in terms of RAID
underneath and a good balance between cost, usable
with more disks, however it might increase the rebuild time when a disk
gets replaced and in theory it should decrease performance as there will be
more disks to acknowledge writes.

Hi Christian,
In theory it should work, but ability to properly run VMs on Gluster is
something relatively new due the improvements on granular healing so I don't
think it has been extended tested.
I wasn't able to find any people using it in production and those I heard are
using for testing.
that different from a normal Linux mount ESXi has some special way to
