fstests includes decent functional tests for online growfs and
shrink, and decent stress tests for crash and log recovery, but no
combination of the two. This test combines bits from a typical
growfs stress test like xfs/104 with crash recovery cycles from a
test like generic/388. As a result, this reproduces at least a
couple recently fixed issues related to log recovery of online
growfs operations.
