We tested this ALPHA release with 4 physical machines for the servers ( NFS and GlusterFS server) and 7 to 11 machines as NFS clients. Some nfs client fan out testing was done with a larger number number of smaller machines.
The Vmware testing was testing for using GlusterFS NFS backend for vmdk. After that we ran some standard filesystem tests - connectathod, iozone, fio, bonnie++ etc inside the vmware partition. However the testing inside the partition was not as intensive as the one we did with the physical servers. An intensive testing inside the vmware partitions is planned between ALPHA and BETA release.
We would be happy to work with you to find out where you system locked up. Did you try to debug what happened ?
It would help if you can describe "lock up the entire machine" in detail. Did other vms running on the machine stop ?
Were you able to kill the test command ? if yes, then did things stabilize after that ?
Please share your config and the commands etc you ran to start the NFS translator.

I'm sorry.. but I don't know how you guys tested this, but using a
bare-bones configuration with the NFS translator and a mirror
configuration between two systems (no performance translators, etc.) I
can lock up the entire system after writing 160-180megs of data.
dd if=/dev/full of=testfile bs=1M count=1000 is enough to lock the
This is on a CentOS 5.4 system with a xen backend (for testing).
I don't know what you guys tested with, but I can't get this stable...
