Thankfull large testing environments are easy these days with virtual machines.
Zhou i wanted to improve on your Failover test idea with the following:
d) Failover test. Shutdown 3 node of Env.D~F while Case.A~
To : Shutdown (whatever) node. Delete contents from harddrive to simulate harddrive failure.
and a new test
Restore test: Add previously broken node back into the cluster.

Maybe we can add tests for the library too? :)
I bring it up because I've been having recent troubles with
glusterfs_fstat() and glusterfs_readdir().
Thanks

Hi,
I'd also like to put my vote in for (more) regression tests -
especially scripted/automated tests of the 'make test' variety which
the public can use.
Given recent data integrity issues, this would help to instill
confidence in GlusterFS releases by allowing users to test a new
release build before putting it into use.
It would also allows users of more exotic environments (i.e.
kernels with PaX or SELinux, Darwin, FreeBSD, etc) to determine
exactly where their environments cause issues. This would make it much
easier for the GlusterFS developers to maintain compatibility with
these platforms.
Kind regards,
Geoff Kassel.

Maybe unit test is too difficult to add to existing code.
I think the following classical cases should be considered integrated
into
the whole suite regression test.
1. Test Environments
a) 4 nodes with DHT.
b) A with all performance xlators.
c) B with all feature xlators.
d) 4*2 nodes with DHT and AFR.
e) D with all performance xlators.
f) E with all feature xlators.
2. Test Case
a) Small file test. Build kernel or gcc or apache over Env.A-F
b) Big file test. Run iozone with file larger than 2G.
c) Huge file test. Construct some huge sparse file larger
than 2T.
d) Failover test. Shutdown 3 node of Env.D~F while Case.A~
Case.C
running.
Thanks
