# FS QA Test 424
#
# This case checks if setting type causes error.
#
# On crc filesystems, xfs_db doesn't take sector size into account
# when setting type, and this can result in an errant crc.
# This issue has been fixed in xfsprogs-dev:
# '55f224b ("xfs_db: update buffer size when new type is set")'
#
# On crc filesystems, when setting the type to "inode" the verifier
# validates multiple inodes in the current fs block, so setting the
# buffer size to that of just one inode is not sufficient and it'll
# emit spurious verifier errors for all but the first.
# This issue has been fixed in xfsprogs-dev:
# '533d1d2 ("xfs_db: properly set inode type")'
