ISCSI

Preliminary (manual) suport for iSCSI in Amahi 6.

From this forums post.

Server side

Set up an iSCSI server on the Amahi box:

bash code
​root@host# yum install scsi-target-utils​

Set up 1 Logical Volume (LV) that will be exported as an iSCSI LUN. The below output shows my LV created for time machine (hence the name lvtime).

bash code
​root@host# lvs | grep time lvtime vg00 -wi-ao 500.00g​

Export the LV: add it to /etc/tgt/targets.conf (note that there's a convention on how to export these!)

bash code
​<target iqn.2010-08.local.bonabo:galileo.lun1> backing-store /dev/vg00/lvtime </target>​

Start the iSCSI target daemon and make sure it starts at boot time:

bash code
​root@host# service tgtd start; chkconfig tgtd on​

Check the exported LUN(s):

bash code
​root@host# tgt-admin -s​

Client side

I installed globalSAN iSCSI Initiator for OS X by Studio Network Solutions (free community supported) iSCSI client for OS X) on the Mac.

I configured it to "see" the iSCSI lun (just type in the iqn IIRC); since it's presented to the OS as a normal disk you need to partition the drive first (it's a blank disk as far as the Mac is concerned). Then configure Time Machine to use that disk and you're done!
