Subject: [PATCH 2/6] btrfs-progs: let user know that devid can be used if path is missing
Date: Fri, 26 Jul 2013 01:35:26 +0800 [thread overview]
Message-ID: <1374773730-29957-3-git-send-email-anand.jain@oracle.com> (raw)
In-Reply-To: <1374773730-29957-1-git-send-email-anand.jain@oracle.com>
When the device disappear the path goes missing,
and that will be the one of the reason that user
will replace the device.
The devid of the missing btrfs device can be
obtained using the new cli option
btrfs fi show --kernel
And which can be used in the replace command.
---
btrfs replace start /dev/sdc /dev/sde /btrfs
Error: Unable to open device '/dev/sdc'
Try using the devid instead of the path
