Subject: [PATCH 3/5] Super-intel: Fix first checkpoint restart
|
|
Git-commit: fdb7e802f4cf64d067c3abaafa35056e2bc1ed43
|
|
Patch-mainline: mdadm-4.3+
|
|
References: jsc#PED-7542

|
|
|
When imsm based array is stopped after reaching first checkpoint and
|
|
then assembled, first checkpoint is reported as 0.
|
|
|
|
This behaviour is valid only for initial checkpoint, if the array was
|
|
stopped while performing some action.
|
|
|
|
Last checkpoint value is not taken from metadata but always starts
|
|
with 0 and it's incremented when sync_completed in sysfs changes.
|
|
|
|
In simplification, read_and_act() is responsible for checkpoint updates
|
|
and is executed each time sysfs checkpoint update happens. For first
|
|
checkpoint it is executed twice and due to marking checkpoint before
|
|
triggering any action on the array, it is impossible to read
|
|
sync_completed from sysfs in just two iterations.
|
|
|
|
The workaround to this is not marking any checkpoint for first
|
|
sysfs checkpoint after RAID assembly, to preserve checkpoint value
|
|
stored in metadata.
