# FS QA Test No. 311

|
# Run various fsync tests with dm flakey in freeze() mode and non freeze()
|
|
# mode. The idea is that we do random writes and randomly fsync and verify that
|
|
# after a fsync() followed by a freeze()+failure or just failure that the file
|
|
# is correct. We remount the file system after the failure so that the file
|
|
# system can do whatever cleanup it needs to and md5sum the file to make sure
|
|
# it matches hat it was before the failure. We also fsck to make sure the file
|
|
# system is consistent.
|
|
#
|
|
# The fsync tester just random writes into prealloc or not, and then fsync()s
|
|
# randomly or sync()'s randomly and then fsync()'s before exit. There are a few
|
|
# tests that were handcrafted to reproduce bugs in btrfs, so it's also a
|
|
# regression test of sorts.
