![]() ![]() Partition types should all be: fd (or "linux raid autodetect"). (If the new drive is bigger, leave the rest of the drive unpartitioned.) The idea is to create partitions of the same size on the new drive. Once you have connected the new drive ( /dev/sdb), boot into your system and use one of cfdisk or fdisk to display the partition information for the existing drive ( /dev/sda on my system). (My instructions are mostly based on this old tutorial but also on this more recent one.) 1- Partition the new drive Reboot with the two drives and resync the array.Test booting off of the original drive.Wipe the original drive by adding it to the RAID array.Reboot using the RAIDed drive and test system.Overviewīefore you start, make sure the following packages are installed: apt-get install mdadm rsync initramfs-tools This post documents the steps I followed to retrofit RAID1 into an existing Debian squeeze installation. The Debian installer will set everything up for you if you choose that option and Ubuntu has alternate installation CDs which allow you to do the same. The best possible time to set this up is of course when you first install the operating system. While such hard disk mirroring is not a replacement for having good working backups, it means that a single drive failure is not going to force me to have to spend lots of time rebuilding a machine. HP setups are fairly easy.I run RAID1 on all of the machines I support. ![]() This will make you to easily identify much more information.įor HP systems, this helps narrow down to a particular model or part number. Nowadays all raid controller manufacturers provide you cmd based utility and web-based utility. If your server configured with any raid, here you can find the details. Type: Direct-Access ANSI SCSI revision: 02 Vendor: MegaRAID Model: LD 0 RAID5 699G Rev: 513O but we are not sure whether the raid has been configured or not. The above Example output shows exact raid controller specifications. Lets check for physical raid ~]# lspci -vv | grep -i raidĠ1:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2208 (rev 01) Identify your server has physical raid controller or not, if not they may be using software raid. ![]()
