Subject: Kernel oops adding bitmap
Date: Mon, 19 Mar 2012 11:44:45 -0500 [thread overview]
Message-ID: <4F67627D.8050205@nuclearwinter.com> (raw)
The following command oopsed.
mdadm -G --bitmap=internal /dev/md0
The array is a two disk raid1 and hosts the root filesystem.
Is it not possible/allowed to add a bitmap to an active/mounted array?
