OpenFiler

Set-up

Installation

1. Download the appropriate appliance from OpenFiler
2. Extract, upload to your ESX and Add to Inventory, and start
3. The machine will attempt use DHCP to assign an IP
4. Browse to the machine, and login using openfiler/password
5. If change IP option doesn't appear on System page, attempt following fix
   1. Login to console of VM (root, no password)
   2. Change line 94 of /opt/openfiler/var/www/includes/network.inc to
   3. exec("sudo ifconfig -a | grep 'eth'",$output);

Create iSCSI Disk

1. Login to OpenFiler (user/pass openfiler/password)
2. First create a partition...
   1. Go to Volumes, and to the Create a new volume group section
   2. Click on the create new physical volumes link
   3. In the resulting Block Device Management page, edit the disk that we want to create the iSCSI storage on.
   4. Find the Create a partition in /dev/sdx section and hit Create (default options)
3. Then create a volume group for iSCSI use...
   1. Go to Volume Groups (right-hand menu) and find the Create a new volume group section
   2. Give the volume group a name (eg volgrp1), select the partition/physical volume and hit Add volume group
   3. Click on the create new physical volumes link
   4. Go to Add Volume, and find the Create a volume in volgrp section
   5. Give the volume a name (eg iSCSIvolgrp), select all space, change Filesystem to iSCSI, and hit Create
4. Create network share
   1. On System tab, find Network Access Configuration
   2. Add in the local network address, or specify individual iSCSI client IP address, etc, and hit Update
5. Enable iSCSI target
   1. On Services tab, Enable iSCSI target server

WARNING: GPT (GUID Partition Table) detected on '/dev/sdc'! The util fdisk doesn't support GPT. Use GNU Parted.


The number of cylinders for this disk is set to 26396.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
