Installing iSCSI Target on Ubuntu Server

Posted by MB in Uncategorized on May 3, 2013

To install iSCSI Target on Ubuntu Server 12.04 LTS, here’s the steps I followed:

sudo apt-get install iscsitarget

That will install the target server, but at the end of the installation, you will get this message:

Setting up iscsitarget (1.4.20.2-5ubuntu3.2) ...
 * iscsitarget not enabled in "/etc/default/iscsitarget", not starting...

edit /etc/default/iscsitarget and change it to read

ISCSITARGET_ENABLE=true

Now, try to start iscsitarget with:

service iscsitarget start

You get:

 * Starting iSCSI enterprise target service
FATAL: Module iscsi_trgt not found.
                                                                         [fail]

What needs to be done is to install iscsitarget-source and iscsitarget-dkms to build the missing module:

apt-get install iscsitarget-source iscsitarget-dkms

The packages install and the module is built automatically

service iscsitarget restart

gives the following result:

 * Removing iSCSI enterprise target devices:                             [ OK ]
 * Starting iSCSI enterprise target service                              [ OK ]
                                                                         [ OK ]

I’m not going to cover configuration of iSCSI targets in this guide. Your comments are welcome below. Thank you!

Windows 8 error code 0x807800C5 during Windows 7 File Recovery backup

Posted by MB in Uncategorized on January 24, 2013

The following error appears if you try to include a system image in your backup using the Windows 7 File Recovery backup tool.

0x807800c5

There was a failure in preparing the backup image of one of the volumes in the backup set.

Details: The mounted backup volume is inaccessible. Please retry the operation.

Error code: 0x807800C5

According to this forum…

For Win 8 only: The Win 7 back up program included with win 8 does not support backing up a image file to any kind of NAS device (UNIX, Linux) . Internally the program gives an error that the NAS device has an incompatible sector mapping type. You can backup to a hard drive that is attached to a different windows machine and then back up that file to your NAS. Convoluted, but it works.

So, backing up a system image to a Samba share is out of the question. To work around this, disable the creation of a system image in your backup.

I haven’t tried backing up to an NTFS-formatted iSCSI LUN, which might work. If anyone has tried that, I’d be interested to know the results.
