Thanks, Uwe. Am I understanding correctly that you're just letting your nodes attach to the iSCSI storage on their own by leaving "node.startup = automatic" in /etc/iscsi/iscsid.conf so the hosts attach to all known targets as they boot, long before oVirt services ever attempt to connect them? I've considered flipping that to
No, I use OVirt to connect to the iSCSI targets, this works as expected. The thing I do not use are OVirt's iSCSI bonds.
What I configure manually is multipathd in order to use round robin policy.
As another poster below mentioned, going the route of two separate iSCSI bonds in the "iSCSI Multipath" section does work when you're adding new storage domains. The aspect he talks about, where you connect both paths and save it, isn't possible if you import an existing storage domain. When importing, the UI won't expose the "Add" button that's available when creating a new domain, so you can't add redundant paths. You can import the storage, then edit it and discover/login to the other path, but that does _not_ save to the database and will not persist across reboots or connect on other hosts you add to the cluster (have to login manually on each). You can't edit your iSCSI bonds and check the box for these manually logged in targets either, they'll never populate in that part of the UI so can't be selected. I think it's just a UI issue because some very easy fidling in the database makes it work exactly as you'd expect (and as it does for domains you newly add instead of importing ).
This sounds quite ugly, I wasn't aware of this.
Sorry, rambling, but I am curious about your "node.startup" setting in iscid.conf. If left at 'automatic' (the default), are your hosts attaching all the disks as they boot and oVirt doesn't mind that? It could be the path I'll take as honestly I'd much prefer configuring the storage connections directly.
As I said, the only thing I change is /etc/multipath.conf: https://lists.ovirt.org/pipermail/users/2017-July/083308.html cu, Uwe _______________________________________________ Users mailing list -- email@example.com To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://firstname.lastname@example.org/message/VDWAU4TE5UY5Z3LQYFWMBIFFCLCFKMQ3/
