# FSQA Test No. 103
|
|
#
|
|
# Test attribute fork teardown. This test is inspired by a regression in XFS
|
|
# that resulted in problematic removal of inodes with remote attribute forks
|
|
# without attribute extents. The attribute fork condition is created by
|
|
# attempting to set larger attribute values on a filesystem that is at or near
|
|
# ENOSPC.
