Best practices for LACP bonds on oVirt
Hello, I’m deploying oVirt for the first time and a question has emerged: what is the good practice to enable LACP on oVirt Node? Should I create 802.3ad bond during the oVirt Node installation in Anaconda, or it should be done in a posterior moment inside the Hosted Engine manager? In my deployment we have 4x GbE interfaces. eth0 and eth1 will be a LACP bond for management and servers VLAN’s, while eth1 and eth2 are Multipath iSCSI disks (MPIO). Thanks, V.

Do all your network settings in ovirt-engine webadmin.

I don't know what is oVirt Node :) And for "generic_linux" I have 95% automation (work in progress). On 07/04/2017 11:20 AM, Vinícius Ferrão wrote:

LOL. It’s the hypervisor appliance, just like RHVH.

Red Hat Virtualization Host (RHVH) is a minimal operating system based on Red Hat Enterprise Linux that is designed to provide a simple method for setting up a physical machine to act as a hypervisor in a Red Hat Virtualization environment. The minimal operating system contains only the packages required for the machine to act as a hypervisor, and features a Cockpit user interface for monitoring the host and performing administrative tasks.
I as Administrator self-know what packages is required for my hardware and I don't need Cockpit. So CentOS minimal is my choice. On 07/04/2017 11:36 AM, Vinícius Ferrão wrote:

Thanks, Konstantin.
Just to be clear enough: the first deployment would be made on classic eth interfaces and later after the deployment of Hosted Engine I can convert the "ovirtmgmt" network to a LACP Bond, right?
Another question: what about iSCSI Multipath on Self Hosted Engine? I've looked through the net and only found this issue: https://bugzilla. redhat.com/show_bug.cgi?id=1193961
Appears to be unsupported as today, but there's an workaround on the comments. It's safe to deploy this way? Should I use NFS instead?
It's probably not the most tested path but once you have an engine you should be able to create an iSCSI bond on your hosts from the engine. Network configuration is persisted across host reboots and so the iSCSI bond configuration. A different story is instead having ovirt-ha-agent connecting multiple IQNs or multiple targets over your SAN. This is currently not supported for the hosted-engine storage domain. See: https://bugzilla.redhat.com/show_bug.cgi?id=1149579
Thanks, V.

Hello,
I’m deploying oVirt for the first time and a question has emerged: what is the good practice to enable LACP on oVirt Node? Should I create 802.3ad bond during the oVirt Node installation in Anaconda, or it should be done in a posterior moment inside the Hosted Engine manager?
In my deployment we have 4x GbE interfaces. eth0 and eth1 will be a LACP bond for management and servers VLAN’s, while eth1 and eth2 are Multipath iSCSI disks (MPIO).
Thanks,
V.
Do all your network settings in ovirt-engine webadmin.

Just to be clear enough: the first deployment would be made on classic eth interfaces and later after the deployment of Hosted Engine I can convert the "ovirtmgmt" network to a LACP Bond, right?
Another question: what about iSCSI Multipath on Self Hosted Engine? I've looked through the net and only found this issue: https://bugzilla.redhat .com/show_bug.cgi?id=1193961
Appears to be unsupported as today, but there's an workaround on the comments. It's safe to deploy this way? Should I use NFS instead?
It's probably not the most tested path but once you have an engine you should be able to create an iSCSI bond on your hosts from the engine. Network configuration is persisted across host reboots and so the iSCSI bond configuration.
A different story is instead having ovirt-ha-agent connecting multiple IQNs or multiple targets over your SAN. This is currently not supported for the hosted-engine storage domain. See: https://bugzilla.redhat.com/show_bug.cgi?id=1149579
Just to be clear, when we talk about bonding on iSCSI, we’re talking about iSCSI MPIO and not LACP (or something similar) on iSCSI interfaces, right?
Yes, correct.
In my case there are two different fabrics dedicated to iSCSI. They do not even transit on the same switch, so it’s plain ethernet (with fancy things, like mtu 9216 enabled and QoS).
So I think we’re talking about the unsupported feature of multiple IQN’s right?
Multiple IQNs on the host side (multiple initiators) should work trough iSCSI bonding as managed by oVirt engine: https://www.ovirt.org/documentation/admin-guide/chap-Storage/#configuring-is... Multiple IQN on your SAN are instead currently not supported by ovirt-ha-agent for the hosted-engine storage domain
Thanks once again, V.

Hello,
I’m deploying oVirt for the first time and a question has emerged: what is the good practice to enable LACP on oVirt Node? Should I create 802.3ad bond during the oVirt Node installation in Anaconda, or it should be done in a posterior moment inside the Hosted Engine manager?
In my deployment we have 4x GbE interfaces. eth0 and eth1 will be a LACP bond for management and servers VLAN’s, while eth1 and eth2 are Multipath iSCSI disks (MPIO).
Thanks,
V.
Do all your network settings in ovirt-engine webadmin.

Hi Simone, i think my post to this list titled "iSCSI multipathing setup troubles" just recently is about the exact same problem, except i'm not talking about the hosted-engine storage domain. i would like to configure _any_ iSCSI storage domain the way you describe it in https://bugzilla.redhat.com/show_bug.cgi?id=1149579#c1. i would like to do so using the oVirt "iSCSI Multipathing" GUI after everything else is setup. i can't find a way to do this. is this now possible? i think the iSCSI Multipathing documentation could be improved by describing an example IP setup for this. thanks a lot matthias

Adding another question to what Matthias has said.
I also noted that oVirt (and RHV) documentation does not mention the supported block size on iSCSI domains.
RHV: https://access.redhat.com/documentation/en-us/red_ hat_virtualization/4.0/html/administration_guide/chap-storage oVirt: http://www.ovirt.org/documentation/admin-guide/chap-Storage/
I’m interested on 4K blocks over iSCSI, but this isn’t really widely supported. The question is: oVirt supports this? Or should we stay with the default 512 bytes of block size?
It does not. Y.
Thanks, V.

Just to be clear enough: the first deployment would be made on classic eth interfaces and later after the deployment of Hosted Engine I can convert the "ovirtmgmt" network to a LACP Bond, right? Another question: what about iSCSI Multipath on Self Hosted Engine? I've looked through the net and only found this issue: https://bugzilla.redhat.com/show_bug.cgi?id=1193961 <https://bugzilla.redhat.com/show_bug.cgi?id=1193961> Appears to be unsupported as today, but there's an workaround on the comments. It's safe to deploy this way? Should I use NFS instead? It's probably not the most tested path but once you have an engine you should be able to create an iSCSI bond on your hosts from the engine. Network configuration is persisted across host reboots and so the iSCSI bond configuration. A different story is instead having ovirt-ha-agent connecting multiple IQNs or multiple targets over your SAN. This is currently not supported for the hosted-engine storage domain. See: https://bugzilla.redhat.com/show_bug.cgi?id=1149579
Hi Simone,
i think my post to this list titled "iSCSI multipathing setup troubles" just recently is about the exact same problem, except i'm not talking about the hosted-engine storage domain. i would like to configure _any_ iSCSI storage domain the way you describe it in https://bugzilla.redhat.com/ show_bug.cgi?id=1149579#c1. i would like to do so using the oVirt "iSCSI Multipathing" GUI after everything else is setup. i can't find a way to do this. is this now possible? i think the iSCSI Multipathing documentation could be improved by describing an example IP setup for this.
thanks a lot matthias

Adding another question to what Matthias has said.
I also noted that oVirt (and RHV) documentation does not mention the supported block size on iSCSI domains.
RHV: https://access.redhat.com/documentation/en-us/red_hat_ virtualization/4.0/html/administration_guide/chap-storage oVirt: http://www.ovirt.org/documentation/admin-guide/chap-Storage/
I’m interested on 4K blocks over iSCSI, but this isn’t really widely supported. The question is: oVirt supports this? Or should we stay with the default 512 bytes of block size?
It does not. Y.
Discovered this with the hard way, the system is able to detect it as 4K LUN, but ovirt-hosted-engine-setup gets confused:
[2] 36589cfc00000071cbf2f2ef314a6212c 1600GiB FreeNAS iSCSI Disk status: free, paths: 4 active
[3] 36589cfc00000043589992bce09176478 200GiB FreeNAS iSCSI Disk status: free, paths: 4 active
[4] 36589cfc000000992f7abf38c11295bb6 400GiB FreeNAS iSCSI Disk status: free, paths: 4 active
[2] is 4k [3] is 512bytes [4] is 1k (just to prove the point)
On the system it’s appears to be OK:
Disk /dev/mapper/36589cfc00000071cbf2f2ef314a6212c: 214.7 GB, 214748364800 bytes, 52428800 sectors Units = sectors of 1 * 4096 = 4096 bytes Sector size (logical/physical): 4096 bytes / 16384 bytes I/O size (minimum/optimal): 16384 bytes / 1048576 bytes
Disk /dev/mapper/36589cfc00000043589992bce09176478: 214.7 GB, 214748364800 bytes, 419430400 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 16384 bytes I/O size (minimum/optimal): 16384 bytes / 1048576 bytes
But whatever, just reporting back to the list. It’s a good ideia to have a note about it on the documentation.
Indeed. Can you file a bug or send a patch to upstream docs? Y.

Just to be clear enough: the first deployment would be made on classic eth interfaces and later after the deployment of Hosted Engine I can convert the "ovirtmgmt" network to a LACP Bond, right? Another question: what about iSCSI Multipath on Self Hosted Engine? I've looked through the net and only found this issue: https://bugzilla.redhat.com/show_bug.cgi?id=1193961 <https://bugzilla.redhat.com/show_bug.cgi?id=1193961> Appears to be unsupported as today, but there's an workaround on the comments. It's safe to deploy this way? Should I use NFS instead? It's probably not the most tested path but once you have an engine you should be able to create an iSCSI bond on your hosts from the engine. Network configuration is persisted across host reboots and so the iSCSI bond configuration. A different story is instead having ovirt-ha-agent connecting multiple IQNs or multiple targets over your SAN. This is currently not supported for the hosted-engine storage domain. See: https://bugzilla.redhat.com/show_bug.cgi?id=1149579
Hi Simone,
i think my post to this list titled "iSCSI multipathing setup troubles" just recently is about the exact same problem, except i'm not talking about the hosted-engine storage domain. i would like to configure _any_ iSCSI storage domain the way you describe it in https://bugzilla.redhat.com/sh ow_bug.cgi?id=1149579#c1. i would like to do so using the oVirt "iSCSI Multipathing" GUI after everything else is setup. i can't find a way to do this. is this now possible? i think the iSCSI Multipathing documentation could be improved by describing an example IP setup for this.
thanks a lot matthias

Hello,
I’m deploying oVirt for the first time and a question has emerged: what is the good practice to enable LACP on oVirt Node? Should I create 802.3ad bond during the oVirt Node installation in Anaconda, or it should be done in a posterior moment inside the Hosted Engine manager?
Adding Simone for this, but I think that hosted-engine --deploy does not know to create bonds, so you better do this beforehand. It does know to recognize bonds and their slaves, and so will not let you configure the ovirtmgmt bridge on one of the slave nics of a bond.
In my deployment we have 4x GbE interfaces. eth0 and eth1 will be a LACP bond for management and servers VLAN’s, while eth1 and eth2 are Multipath iSCSI disks (MPIO).
You probably meant eth2 and eth3 for the latter bond. This is probably more a matter of personal preference than a result of a scientific examination, but I personally prefer, assuming that eth0 and eth1 are managed by a single PCI component and eth2 and eth3 by another one, and especially if they are different, and using different kernel modules, to have one bond on eth0 and eth2, and another on eth1 and eth3. This way, presumably, if some (hardware or software) bug hits one of the PCI devices, both bonds hopefully keep working. Just my two cents,
Thanks, V.

Hello,
I’m deploying oVirt for the first time and a question has emerged: what is the good practice to enable LACP on oVirt Node? Should I create 802.3ad bond during the oVirt Node installation in Anaconda, or it should be done in a posterior moment inside the Hosted Engine manager?
Adding Simone for this, but I think that hosted-engine --deploy does not know to create bonds, so you better do this beforehand. It does know to recognize bonds and their slaves, and so will not let you configure the ovirtmgmt bridge on one of the slave nics of a bond.
Yes, exactly.
In my deployment we have 4x GbE interfaces. eth0 and eth1 will be a LACP
bond for management and servers VLAN’s, while eth1 and eth2 are Multipath iSCSI disks (MPIO).
You probably meant eth2 and eth3 for the latter bond.
This is probably more a matter of personal preference than a result of a scientific examination, but I personally prefer, assuming that eth0 and eth1 are managed by a single PCI component and eth2 and eth3 by another one, and especially if they are different, and using different kernel modules, to have one bond on eth0 and eth2, and another on eth1 and eth3. This way, presumably, if some (hardware or software) bug hits one of the PCI devices, both bonds hopefully keep working.
Just my two cents,
Thanks, V.

It’s one single card with 4 interfaces. It came onboard on the IBM System x3550 M4 servers that I’m using and they are Intel based, don’t remember exactly which chipset. Anyway this is interesting, I really avoid mixing different controllers on bonding to keep things stable, but you’ve a point.
