Subject: [PATCH 01/41] Remove hardcoded checkpoint interval checking
|
|
|
|
Mdmon assumes that kernel marks checkpoint every 1/16 of the volume size
|
|
and that the checkpoints are equal in size. This is not true, kernel may
|
|
mark checkpoints more frequently depending on several factors, including
|
|
sync speed. This results in checkpoints reported by mdadm --examine
|
|
falling behind the one reported by kernel.
|
|
|
|
Remove hardcoded checkpoint interval checking.
