We did a tla install of 906 yesterday and the problem seems to have
been resolved by that build. Thanks and keep up the great work! -Mic Anand Avati wrote: Mickey, Can you check if the latest tla code has resolved the issues you faced?

We have a bunch of vol files that test a few different server configurations. After mountpoints are prepared we have other scripts that start virtual machine on the various mounts. In other words I have a directory called "/glustermounts/" and in that directory I have the files: main.vol main.vol.ib main.vol.tcp stripe.vol.ha stripe.vol.tcp after running "/etc/init.d/glustersystem start" I will have the following mount points: /system (our default mount, we actually store the vol files here) /mnt/main /mnt/stripe The output shows me if any vol file failed to mount and it automatically attempts the next one (ex" "mounting main.vol failed, trying main.vol.ib"). We simply arrange vol files from most features to least. We have a separate script which starts up a virtual machine on each test mount. This is the actual "test" we use as it creates symbolic links, uses mmaps etc but it's pretty specific to us. This closely mirrors how we use it in production. I've included out startup script and I would suggest you simply run something similar to your production on a few mounts in the same way we have. I may share this with the entire group although there are probably better init scripts out there. This one does kill all processes attached to a mount point which is useful. Let me know if you have any questions!

I've looked high and low for the unit tests that the GlusterFS devs are meants to be using (ala http://www.gluster.org/docs/index.php/GlusterFS_QA) so that I can do my own testing, but I've not been able to find them. If it's tests you've developed in-house, would you be interested in releasing them to the wider community? Kind regards, Geoff Kassel.

Our initial tests are with ibverbs/HA but no performance translators.
