From c32f3410245d666c5bea0e3b6e1e8aad6091b19f Mon Sep 17 00:00:00 2001 From: Vivek Goyal Date: Thu, 29 Mar 2012 10:09:44 +0200 Subject: [PATCH] virtio-blk: Call revalidate_disk() upon online disk resize commit e9986f303dc0f285401de28cf96f42f4dd23a4a1 upstream. If a virtio disk is open in guest and a disk resize operation is done, (virsh blockresize), new size is not visible to tools like "fdisk -l". This seems to be happening as we update only part->nr_sects and not bdev->bd_inode size. Call revalidate_disk() which should take care of it. I tested growing disk size of already open disk and it works for me.
