[Gluster-devel] Problem with TLA ver > 887

[Mickey Mazarick]

Heh our tests are kind of an unholy mess... but here's the part I think 
is useful:
We use a startup script that will iterate through vol files and mount 
the first available file on the list. 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!

Thanks!
