The configuration file can be overridden by using a Kernel argument. The file has the advantage of being able to pre-configure the system’s behavior, and can also be manually edited: BOOT_DEGRADED=true The dpkg-reconfigure mdadm process will change the /etc/initramfs-tools/conf.d/mdadm configuration file. To reconfigure mdadm enter the following: sudo dpkg-reconfigure mdadm

The dpkg-reconfigure utility can be used to configure the default behavior, and during the process you will be queried about additional settings related to the array. Booting to a degraded array can be configured several ways: Booting to the initramfs prompt may or may not be the desired behavior, especially if the machine is in a remote location.
INSTALL UBUNTU CREATE BOOT PARTITION MANUAL
Once the initramfs has booted there is a fifteen second prompt giving you the option to go ahead and boot the system, or attempt manual recover. If the array has become degraded, due to the chance of data corruption, by default Ubuntu Server Edition will boot to initramfs after thirty seconds.

When this happens, using Software RAID, the operating system will place the array into what is known as a degraded state. Degraded RAIDĪt some point in the life of the computer a disk failure event may occur. The installation process will then continue normally. Repeat steps above for the other partitions.

Use the rest of the free space on the device, choose the format (default is ext4) and select / as mount point, then Create. Calculating the swap partition size for servers is highly dependent on how the system is going to be used.įor the / partition once again select the RAID 1 device then “Add GPT Partition”. And finally, select Create.Ī swap partition size of twice the available RAM capacity may not always be desirable, especially on systems with large amounts of RAM. Enter the partition size, then choose swap in Format. This partition will be the swap partition, and a general rule for swap size is twice that of RAM. Select the RAID 1 device created ( md0) then select “Add GPT Partition”.

Repeat steps above for the other RAID devices. The new RAID device ( md0 if you did not change the default) will show up in the available devices list, with software RAID 1 type and the chosen size. The real devices can be marked as active or spare, by default it becomes active when is selected. Select the devices that will be used by this RAID device. Using RAID0 or RAID1 only two drives are required. In order to use RAID5, RAID6 and RAID10 you need more than two drives. Now to create the RAID device select Create software RAID (md) under AVAILABLE DEVICES.Īdd the name of the RAID disk (the default is md0).įor this example, select “1 (mirrored)” in RAID level, but if you are using a different setup choose the appropriate type (RAID0 RAID1 RAID5 RAID6 RAID10).

Next, enter the partition size, then choose the desired Format ( ext4) and /boot as mount point. So select one of the devices listed in available devices and Add GPT Partition. RAID Configurationįollow the installation steps until you get to the Guided storage configuration step, then:Ĭreate the /boot partition in a local disk. This section will guide you through installing Ubuntu Server Edition using two RAID1 partitions on two physical hard drives, one for / and another for swap.

The RAID software included with current versions of Linux (and Ubuntu) is based on the ‘mdadm’ driver and works very well, better even than many so-called ‘hardware’ RAID controllers. RAID is implemented in either software (where the operating system knows about both drives and actively maintains both of them) or hardware (where a special controller makes the OS think there’s only one drive and maintains the drives ‘invisibly’). Redundant Array of Independent Disks “RAID” is a method of using multiple disks to provide different balances of increasing data reliability and/or increasing input/output performance, depending on the RAID level being used.
