Technically yes, I believe there's a 10 minute or so delay before it'll come up on the other host. Pretty sure iscsi is not available for now, only NFS. On Wed, Apr 16, 2014 at 4:08 AM, Maurice James <mjames@media-node.com> wrote:

iSCSI support is currently under development. The feature page is http://www.ovirt.org/Features/Self_Hosted_Engine_iSCSI_Support You're welcome to help testing proposed patch http://gerrit.ovirt.org/26501 IMPORTANT: Don't use this build on production environment / storage! In order to test it you can download ovirt-hosted-engine-setup from this jenkins build: http://jenkins.ovirt.org/view/Packaging/job/ovirt-hosted-engine-setup_master... and ovirt-hosted-engine-ha from this jenkins build:: http://jenkins.ovirt.org/view/Packaging/job/ovirt-hosted-engine-ha_create_rp... Above builds include also experimental support for tagged vlans and bond interfaces http://gerrit.ovirt.org/25894 Since this is an experimental development build, please don't open new BZ, just send me an email attaching vdsm, sanlock, libvirt, hosted-engine setup and ha logs. Thanks

There is no config file, but if you really want to change it, then you can play with the values in: /usr/lib/python2.6/site-packages/ovirt_hosted_engine_ha/agent/constants.py (or python 2.7 depending on your setup) In the case when you pull the plug it should be driven by ENGINE_BAD_HEALTH_EXPIRATION_SECS --Jirka On 04/16/2014 04:43 AM, Andrew Lau wrote:

Hi,
In the case when you pull the plug it should be driven by ENGINE_BAD_HEALTH_EXPIRATION_SECS
Actually, if you pull the plug, then the other host will detect that the other host is not responding after about a minute. And then it will try to start the VM.
Pretty sure iscsi is not available for now, only NFS.
