Easy Snippet: Xenserver / linux software raid

Sunday, June 28, 2015

I want my Storage Repository (SR) run under the software RAID (RAID1). My xenserver version 6.5. XenServer 6.5 do not load soft raid kernel modules on boot. To load soft raid manually run :

modprobe raid1

To load the soft raid module on boot, we can follow this steps : http://discussions.citrix.com/topic/360943-software-raid-mdadm-on-xenserver-65-unexpected-failure/?p=1855912

To build the RAID array :

 
mknod /dev/md1 b 9 1

mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/sdb1 /dev/sdc1

/dev/sdb1

and

/dev/sdc1

is using linux raid autodetect as the partition type. Use fdisk to create those partition.

To check the RAID building process :

cat /proc/mdstat
