Continuation from Home Linux File Server<\/a><\/p>\n

Challenge 4 and 5: Setup and configure iSCSI Target<\/strong> and Mount the LUN from a separate computer<\/strong><\/p>\n

I’m going to be using a guide here: [Set up an iSCSI Target and Initiator<\/a>]<\/p>\n

<\/p>\n

Preparation<\/strong><\/p>\n

So, the first concept is to make the linux box an iSCSI target. We’ve originally mounted and formatted \/dev\/md0 to ext4, so in order to property iSCSI this we’ll need to undo our mounting and let the destination machines use this as they want to use it.<\/p>\n

So, I umount \/dev\/md0<\/code> and remove it from \/etc\/fstab<\/code>. For the sake of validating it, I reboot the box.<\/p>\n

Setting up iSCSI Target<\/strong><\/p>\n

Gotta install some tools and services:<\/p>\n

# yum install scsi-target-utils\r\n# service tgtd start\r\n# chkconfig tgtd on<\/pre>\n
and then we setup \/etc\/tgt\/targets.conf<\/code> with the following:<\/p>\n
\r\n# Set the driver. If not specified, defaults to \"iscsi\".\r\n#\r\n# This can be iscsi or iser. To override a specific target set the\r\n# \"driver\" setting in the target's config.\r\ndefault-driver iscsi\r\n<target iqn.2018-01.eye-scrunchie:target1>\r\n        backing-store \/dev\/md0\r\n<\/target>\r\n<\/pre>\n
Reload the new configuration:<\/p>\n
# service tgtd restart<\/pre>\n
and check the configuration:<\/p>\n
# tgt-admin --show\r\nTarget 1: iqn.2018-01.eye-scrunchie:target1\r\n    System information:\r\n        Driver: iscsi\r\n        State: ready\r\n    I_T nexus information:\r\n    LUN information:\r\n        LUN: 0\r\n            Type: controller\r\n            SCSI ID: IET     00010000\r\n            SCSI SN: beaf10\r\n            Size: 0 MB, Block size: 1\r\n            Online: Yes\r\n            Removable media: No\r\n            Prevent removal: No\r\n            Readonly: No\r\n            Backing store type: null\r\n            Backing store path: None\r\n            Backing store flags:\r\n        LUN: 1\r\n            Type: disk\r\n            SCSI ID: IET     00010001\r\n            SCSI SN: beaf11\r\n            Size: 533 MB, Block size: 512\r\n            Online: Yes\r\n            Removable media: No\r\n            Prevent removal: No\r\n            Readonly: No\r\n            Backing store type: rdwr\r\n            Backing store path: \/dev\/md0\r\n            Backing store flags:\r\n    Account information:\r\n    ACL information:\r\n        ALL\r\n<\/pre>\n
Step 4 done!<\/p>\n
Mounting my iSCSI Target on my Initiator<\/strong><\/p>\n
For Step 5, i’m using a Windows 10 machine and the iSCSI Initiator Desktop App.<\/p>\n
For Target:<\/code> I give it the IP Address of my Linux Virtuabox (192.168.1.38) and click Quick Connect...<\/code><\/p>\n
The I go to my Disk Management, Initialize the Disk, give it a Letter, and done!<\/p>\n
Step 5 Done!<\/p>\n","protected":false},"excerpt":{"rendered":"
