hi Vijai, Joseph,
In 2 of the last 3 build failures, http://build.gluster.org/job/regression/4479/console, http://build.gluster.org/job/regression/4478/console this test(tests/bugs/bug-1090042.t) failed. Do you guys think it is better to revert this test until the fix is available? Please send a patch to revert the test case if you guys feel so. You can re-submit it along with the fix to the bug mentioned by Joseph.
Pranith.

> hi,
> In the latest build I fired for review.gluster.com/7766
> (http://build.gluster.org/job/regression/4443/console) failed because of
> spurious failure. The script doesn't wait for nfs export to be
> available. I fixed that, but interestingly I found quite a few scripts
> with same problem. Some of the scripts are relying on 'sleep 5' which
> also could lead to spurious failures if the export is not available in 5
> seconds. We found that waiting for 20 seconds is better, but 'sleep 20'
> would unnecessarily delay the build execution. So if you guys are going
> to write any scripts which has to do nfs mounts, please do it the
> following way:
>
> EXPECT_WITHIN 20 "1" is_nfs_export_available;
> TEST mount -t nfs -o vers=3 $H0:/$V0 $N0;
>
> Please review http://review.gluster.com/7773 :-)

> I saw one more spurious failure in a snapshot related script
> tests/bugs/bug-1090042.t on the next build fired by Niels.
> Joesph (CCed) is debugging it. He agreed to reply what he finds and share it

> I encourage you guys to share what you fix to prevent spurious failures in
