# 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.
