# FS QA Test No. 068 # FSQA Test No. 068
# #
# Test Linux LVM snapshot creation # Test case to reproduce xfs_freeze hang under filsystem load.
# # The fail case for this test is a hang on an xfs_freeze.
# The timing and placement of kills and waits is particularily sensitive.
# Don't change them unless you want to spend some time getting it right again.
