{{From|https://help.ubuntu.com/community/DegradedRAID}} {{Languages|UbuntuHelp:DegradedRAID}} == Introduction == This page outlines the procedure needed in order to automatically boot from a degraded '''Software RAID''' partition when using Ubuntu 8.04 LTS (Hardy Heron). == Upgrading == First, make sure all updates are applied to the system. Perform the updates by entering the following in a terminal: <pre><nowiki> sudo apt-get update && sudo apt-get -y dist-upgrade </nowiki></pre> == Updating Grub == Once the utilities are upgraded, '''grub''' will need to be installed on each drive in the Array: Determine if your /boot is on a RAID device: <pre><nowiki> df /boot | tail -n 1 | awk '{print $1}' </nowiki></pre> If so, install grub to that device. <pre><nowiki> sudo grub-install /dev/md0 </nowiki></pre> '''Note:''' replace ''/dev/md0'' with the actual '''/boot''' device in your machine. == Boot Configuration == With grub updated, configure the boot behavior. There are several options available, see the [https://help.ubuntu.com/8.10/serverguide/C/advanced-installation.html#raid-degraded Degraded RAID] section of the Ubuntu Server Guide for details. == See Also == For information on installing Ubuntu Server Edition on Software RAID see [[UbuntuHelp:Installation/SoftwareRAID|Installation/SoftwareRAID]]. Also, refer to LP #290885: * [https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/290885 SRU: Backport of Boot Degraded RAID functionality from Intrepid to Hardy]. [[category:UbuntuHelp]]
