We're having a series of problems with the valgrind included in xenial[1] that have led us to restrict all valgrind tests to centos nodes. At teh same time, we're also seeing spurious ENOSPC errors from btrfs on both centos on xenial kernels[2], making trusty the only distro where btrfs works reliably. Teuthology doesn't handle this well when it tries to put together the test matrix (we can't test filestore+btrfs+valgrind). The easiest thing is to 1/ Stop testing filestore+btrfs for luminous onward. We've recommended against btrfs for a long time and are moving toward bluestore anyway. 2/ Leave btrfs in the mix for jewel, and manually tolerate and filter out the occasional ENOSPC errors we see. (They make the test runs noisy but are pretty easy to identify.) If we don't stop testing filestore on btrfs now, I'm not sure when we would ever be able to stop, and that's pretty clearly not sustainable. Does that seem reasonable?
