After modifying logical volume size, lsblk command still shows previous
size of logical volume.

When the driver gets any event from firmware it schedules rescan worker
with delay of 10 seconds. If array expansion is so quick that it gets
completed in a second, the driver could not catch logical volume expansion
due to worker delay.

Since driver does not detect volume expansion, driver would not call
rescan device to update new size to the OS.
