From 97880078922049b08ae28af2579cca9610e642dc Mon Sep 17 00:00:00 2001 From: Hao Liu Date: Wed, 10 Dec 2014 15:14:26 +0800 Subject: [PATCH] storage: Check stderr when matching parted output In old version of parted like parted-2.1-25, error message is shown in stdout when printing a disk info without disk label. Error: /dev/sda: unrecognised disk label This line has been moved to stderr in newer version of parted. So we should check both stdout and stderr when locating this message.
