[Gluster-users] Problems with Glusterfs and OpenVz

[Pablo Godel]

I tried this some months ago and it worked, but performance suffered,
specially with PHP and APC enabled which tried to use shared memory.

I guess  since you are not able to fully test, you don't know yet, I would
like to know what is the performance you are experiencing.

any others with comments regarding this?

Thanks
Pablo
