Hi Dietmar, While testing patches send to zfs-plugin I have come across a small bug related to the iscsi options used with the kvm command to start a vm. This bug was discovered while testing the patch adding host and target group to comstar. The bug is that since initiator name is not part of the options to iscsi libiscsi will use a default initiator name which is:
"By default qemu will use the iSCSI initiator-name 'iqn.2008-11.org.linux-kvm[:<name>]' but this can also be set from the command line or a configuration file." (man kvm) The initiator name can be configured on the command line like: -iscsi 'initiator-name=iqn.1993-08.org.debian:01:ddcb3fadcb55' The initiator name should be parsed from: /etc/iscsi/initiatorname.iscsi Such a file will exist on every node in a cluster and each node will have a unique initiator name. As long as every node's initiator name is registered as a member of the host group on the storage server any initiator name from one of the nodes will be accepted. Failing to supply a initiator name on the command line means that the storage server must assign a target to host and target group ALL (target can be accessed from any client on the network!) Should I make a patch which applies the above? It will not brake anything for current setups since current setups must already be configured to use ALL for host and target groups since this is the only way the current setup will work. -- Hilsen/Regards Michael Rasmussen Get my public GnuPG keys: michael <at> rasmussen <dot> cc http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xD3C9A00E mir <at> datanom <dot> net http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xE501F51C mir <at> miras <dot> org http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xE3E80917 -------------------------------------------------------------- /usr/games/fortune -es says: Look, we play the Star Spangled Banner before every game.
