Hi Zack,
http://pulpito.ceph.com/loic-2014-06-27_18:45:37-upgrade:firefly-x:stress-split-wip-8475-testing-basic-plana/329515/
seems to indicate that the tasks cannot obtain the machines it needs:
2014-06-27T17:55:19.072 INFO:teuthology.task.internal:Locking machines...
2014-06-27T17:55:19.110 INFO:teuthology.task.internal:waiting for more machines to be free (need 3 see 5)...
2014-06-27T17:55:29.175 INFO:teuthology.task.internal:waiting for more machines to be free (need 3 see 5)...

2014-06-28T03:22:23.787 INFO:teuthology.task.internal:waiting for more machines to be free (need 3 see 0)...
Is it something expected (for instance when tasks with a higher priorty take precedence) ? If it is then all that's needed is patience right ?
Cheers

Technically yes.
If queue is busy - patience is needed.
Assuming that there are no runs in the queue which are hung. Zack is
diligently looking and fixing to prevent hung tests. If we see runs
older then say one day, we kill them (altho 'teuthology-kill' is not
working for me today :( )
Another option to speed up run - use PRIO (for priority) when
scheduling it and/or use not plana machines as they are in high
demand.
Thx

Hi Yuri,
This is reassuring :-) Patience is easy during the week-ends.

Unless there is a specific reason to run rados / upgrade suites on plana machines, which other types of machine do you recommend ?

Hi Loic,
At this point I don't really have a way to look back in time to see
what was going on, but in the future when jobs are blocked waiting for
machines for unreasonable periods it's useful to know what is holding
them:
teuthology-lock --brief -a --machine-type plana | sort -k +4
Thanks,
Zack

Hi Zack,
Thanks for the tip, I'll try it next time :-)
Cheers
