From 27655e9db47965f640b3ef5a6796587d58b523eb Mon Sep 17 00:00:00 2001 From: Mahesh Rajashekhara Date: Tue, 1 Feb 2022 15:48:38 -0600 Subject: [PATCH] scsi: smartpqi: Update volume size after expansion 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.
