I'm not going to go into every test failure, but it
definitely sounds like you are running on a RAID device that
exposes sunit/swidth to mkfs. That is the likely cause of all the
log size and stripe unit related failure. Also, you are running
deprecated tests and some that are known to fail. You should run the
"auto" group tests as those are the known "good" tests that should
be regularly run. i.e. Try running:

# MKFS_OPTIONS="-d noalign" ./check -g auto

and that should solve amny of the log size and enospc failures that
you are seeing. What is left is likely to be things we really
need to fix.

FYI, we know there are things that need to be fixed - I currently
see 13 tests from the auto group fail on CRC enabled filesystems:

Failures: generic/263 generic/313 xfs/021 xfs/033 xfs/066 xfs/073
xfs/189 xfs/216 xfs/295 xfs/296 xfs/299 xfs/301 xfs/302
Failed 13 of 240 tests

Several of these are test issues, some of them are bugs that need
triage and fixing. We're slowly working our way through them fixing
the test issues - we've been fixing 3-4 a week for the past few
weeks, so the situation is getting much better - 3 weeks ago the
same test machine was seeing ~25 failures in a run.
