Tests sometimes fail on a diskless NFS-mounted node

[aprsa]

I'm running make check on a diskless node that pxe-boots from NFS, and I am running into intermittent test failures:

rm: cannot remove '/home/andrej/system/munge-0.5.14/t/trash-directory.0110-munged-origin-addr/log-23162/.nfs00000000052c05610000021c': Device or resource busy
FATAL: Cannot prepare test area
ERROR: 0110-munged-origin-addr.t - missing test plan
ERROR: 0110-munged-origin-addr.t - exited with status 1

I've had 8 tests fail with the same output. They seem perfectly harmless and I'm guessing it's a race condition between the nfs lock and rm. I figured I'd report it still in the hope it helps.

Thanks for reporting this. I suspect you're right about it being a race condition between nfs lockfiles and rm. I've worked around these types of errors in the past by moving test suite output files to /tmp.

SHARNESS_TRASH_DIRECTORY is defined in t/sharness.sh and becomes the HOME directory from which tests are run. You can't redefine it, but you can specify root which is prepended to it. Assuming /tmp is some non-nfs local filesystem, try running something like make check root=/tmp/munge-$$ and see if that helps.

I've been meaning to write a wiki page documenting the test suite and the variables that influence its behavior. I'll move that up on my list.

Nice!

Yay! I'll make sure to document this in the wiki.
