[ovirt-users] Re: How I'd like to contribute
I would like to know why "vdsm-tool config-lvm-filter"
makes
you pull your hair out.
It was designed to help people configure their system
correctly without pulling their hair out trying to
understand how lvm filter works, and avoid the many
wrong ways it can be used.
Honestly, it is just from a lack of understanding of what is happening when it does break
(as it is for us when doing a hypervisor install on a fresh box). Normally, I can just dig
through the stack and figure out what is happening. There are enough areas where I
don't have some foundations that I'm not able to do so here (yet).
For example, I don't quite understand iSCSI, Multipath, etc enough to know what is
breaking, and why.
I'm accustomed to being able to dig deeper at each level until I can generally see
what is breaking.
This confusion will go away as I get a bit more experience and have a "map" of
what is going on on this level.
FWIW, I started reading the Libvirt book previously mentioned and it's pretty straight
forward. It looks like I just need to get through this enough to get a good foothold so
that I can figure out how to either fix things when they break or point out properly why
something is breaking (so I can get the appropriate help).
Do you have some specific areas you would like to improve?
Actually, yes :) In:
1. Learn libvirt more (in progress)
2. Review source for vdsm-tool to have a better sense what is going on
3. Setup an iSCSI system so that I can make luns, build a system, play with storage pools
this way
Thanks for asking this. It's an interesting question.
Kindest Regards,
