Subject: [PATCH 083/115] vdo: extend volume and pool without flush
|
||
|
|
|
||
|
|
When the volume size is extended, there is no need to flush
|
||
|
|
IO operations (nothing can be targeting new space yet).
|
||
|
|
VDO target is supported as target that can safely work with
|
||
|
|
this condition.
|
||
|
|
|
||
|
|
Such support is also needed, when extending VDOPOOL size
|
||
|
|
while the pool is reaching its capacity - since this allows
|
||
|
|
to continue working without reaching 'out-of-space' condition
|
||
|
|
due to flushing of all in flight IO.
|
||
|
|
|
||
|
|
(cherry picked from commit e26c21cb8d5841141dcfdfc77f46da1108a81255)
