Adding ISCSI volumes to the nodes

This post is part of a series that will deal with setting up a MySQL shared storage cluster using VirtualBox & FreeNAS. In this post we deal with the setup of an iscsi volume on two nodes. The text in bold below represent commands to be executed in the shell.

  • yum install iscsi-initiator-utils
  • iscsiadm -m discovery -t st -p 192.168.3.100 <- This command should show the LUNs advertised by FreeNAS.

iscsi_discovery

  • /etc/init.d/iscsi restart
  • fdisk -l | grep Disk <- This should show new devices that are available. In this case it’s /dev/sdb and /dev/sdc
  • mkfs.ext3 /dev/sdb <- Format device.
  • Repeat all steps, apart from the mkfs.ext3 command, for node2.
