disk resize question
by Dev Ops
Hey all, quick question regarding new VM instances in oVirt. Is there any way to grow the thin disk associated with a template on instantiation? This would allow facilities like cloud-init resizefs to actually be useful. Been searching around a bit and it seems like this is not a thing in oVirt.
Thanks!!

Single Hyperconverged Node Gluster Config
by Jeremy Tourville
Hello,
I am trying to setup a single hyperconverged node. The disks that I will be using for the creation of my engine and all VMs are on a RAID 5. This volume is using hardware raid with an LSI controller (LSI 9361-4i). I am unsure of the appropriate values to use for the Gluster config. Here is the info about my environment.

In DNS I have defined .3 address as vmh.cyber-range.lan and .4 is defined as ovirtbe.cyber-range.lan. .3 is the frontend IP and .4 is the backednd IP.
I have done the following so far with my Gluster Config file, I'm sure it needs further edits.

Can anyone kindly provide the correct values and corrections needed? I am not nearly as good with Linux storage as I'd like to be. Please let me know if any further info is required. Many thanks in advance!!!

NFS Multipathing
by Thomas Letherby
Hello all,
I've been looking around but I've not found anything definitive on whether
Ovirt can do NFS Multipathing, and if so how?
Does anyone have any good how tos or configuration guides?
Thanks,
Thomas

Re: NFS Multipathing

Hi, It should be possible, as oVirt is able to support NFS 4.1 I have a Synology NAS which is also able to support this version of the protocol, but never found time to set this together and test it until now. Reagrds

HowTo trace errors or issues ?
by Sven Achtelik
Hi All,
I would like to understand how to find the point that fails when starting from the Event showing in the GUI. With that event I get an correlation ID and how would I trace all the following tasks, actions or events that are connected to that correlation ID ?
Is it something like CorrelationID -> TaskID -> CommandID or how do things connect ? Is there some documentation I could look at ?
Thank you,
Sven
