Hi, Well, in fact an iSCSI SAN can be used in several ways:
1.- Export the iSCSI volume with a NAS. This is supported through the tm shared drivers[1]. There are also drivers for the MooseFS [2]. If you are using this approach you can improve the efficiency by using a FS that support snapshotting (ZFS, BRTFS - some efforts undergoing in this area) or image formats that can do that (e.g. qcow2 see [3]). This requires some scripting to adapt it to you workflow. 2.- Create LVM volumes on the iSCSI for the images using golden LVM devices. This may require some LVM cluster support. You may take the LVM driver as a basic example which can be tailored to fit your specific scenario [4] 3.- Create the devices and export them through iSCSI. This requires some modification of the TM drivers to restart initiators. Some information of options 2 and 3 can be found in [5] [1] http://www.opennebula.org/documentation:rel3.0:sfs [2] http://opennebula.org/software:ecosystem:moosefs [3] https://support.opennebula.pro/entries/348847-using-qcow-images [4] http://www.opennebula.org/documentation:rel3.0:lvm [5] http://dev.opennebula.org/issues/32 Hope this helps Cheers Ruben On Tue, Nov 22, 2011 at 1:34 AM, Anthony Goddard <[email protected]> wrote: > Wondering if anyone who's using an iSCSI SAN for storage with OpenNebula > would mind posting a short / high level overview of how their setup is > configured?
