# From the PV
# o Summary of testing:
# 1. mkfs.xfs a default filesystem, note agcount value.
# 2. dd zero first sector and repair and verify.
# 3. mkfs.xfs overriding agcount to a smaller value
# (ie. each AG is bigger)
# 4. dd zero first sector, repair and verify.
# -> old mkfs.xfs will cause repair to incorrectly
# fix filesystem, new mkfs.xfs will be fine.
