Subject: [PATCH 1/5] Remove hardcoded checkpoint interval checking
|
|
Git-commit: aec3b907de48be54106600a1ecb69d1231f4801d
|
|
Patch-mainline: mdadm-4.3+
|
|
References: jsc#PED-7542

|
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.
