Subject: [PATCH 175/201] mdadm/Grow: Update reshape_progress to need_back
|
||
|
|
after reshape finishes
|
||
|
|
|
||
|
|
It tries to update data offset when kicking off reshape. If it can't
|
||
|
|
change data offset, it needs to use child_monitor to monitor reshape
|
||
|
|
progress and do back up job. And it needs to update reshape_progress
|
||
|
|
to need_back when reshape finishes. If not, it will be in a infinite
|
||
|
|
loop.
