I use default local.sh as a configuration, this is a single VM. and yes, wait_update_facet_cond() just times out while I set an explicit limit for a whole test (conf-sanity) in this case. I don't quite understand the test - it doesn't fail if wait_update_facet_cond() times out. what's the point of this waiting?

[Andreas Dilger]

Alex, what do you have in your config for $mds1_HOST (maps to $mds_HOST if unset)? Can the client $PDSH to that node (should be a no-op if it is a single client).

According to the Gerrit Janitor test logs, the test is taking 1200s to finish, and the wait_update_facet_cond() is continually timing out, but this does not cause an error return:

I'm not sure if that is how this test is supposed to work or not, but 1200s is a long time and probably the test should be added to the SLOW list.

conf-sanity/119 times out every time with the patch:

It looks like this was introduced by patch https://review.whamcloud.com/27753 "LU-9699 osp: don't assert on OSP duplicating".

The wait_update_cond() call in test_119 should take a hostname as an argument instead of a facet name.
