but VDSM when it starts, it runs command: /usr/sbin/iscsiadm -m node -T iqn.1984-05.com... -I default -p <IP>:3260,1 -l and when the above IP address is unavailable (I unpluged array cable for testing HA), it hangs and cannot read vd.conf file, so I do not know from where VDSM get above IP addres and why it tires to logon to iSCSI share itself. Because iSCSI daemon does it correctly and do not create sessions where the link is not active. 2017-03-13 16:15 GMT+01:00 Chris Adams <cma@cmadams.net>:
It's easy enough to verify; just SSH in to the physical machine running the hosted engine and look. You can see the qemu command line, follow the links to the block device, then look at the LVM physical volume and see that it is a multipath device.

Are you 1000% sure? Because during startup vmsd the comman iscsiadm <parameters> <target> is executed, In my opinion vmsd should rely on /var/lib/iscsi settings.

OK, but what your script do, only add paths by the iscsiadm command, but the question is if hosted-engine can see it. I do not know how to add an extra path, for example, when I congirured hosted-engine during installation there was only one path in the target, but now there are four. So how can I verify how many paths are now, and how eventually change it.
oVirt access iSCSI storage through multipath devices, so adding a path to the multipath device will work. Adding an additional path with iscsiadm causes multipathd to recognize it; you can verify that with "multipath -ll". -- Chris Adams <cma@cmadams.net> _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
