# 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")'

# for different sector sizes, ensure no CRC errors are falsely reported.

# Supported types include: agf, agfl, agi, attr3, bmapbta,
# bmapbtd, bnobt, cntbt, data, dir3, dqblk, inobt, inodata,
# inode, log, rtbitmap, rtsummary, sb, symlink, text, finobt.
# For various sector sizes, test some types that involve type size.
#
# NOTE: skip attr3, bmapbta, bmapbtd, dir3, dqblk, inodata, symlink
# rtbitmap, rtsummary, log
