What we are seeing more and more is that if we do an operation like expose a
new LUN and configure a new storage domain, that all of the hyervisors go
"red triangle" and "Connecting..." and it takes a very long time
(all day)
to straighten out.
My guess is that there's too much to look at vdsm wise and so it's waiting a
short(er) period of time for a completed response than what vdsm is going to
us, and it just cycles over and over until it just happens to work.
Please upgrade. We have solved issues and improved performance and scale
substantially since 3.6.
You may also wish to apply lvm filters.
Y.
Oh, we know and are looking at what we'll have to do to upgrade. With that
said, is there more information on what you mentioned as "lvm filters" posted
somewhere?
Also, would VM reduction, and IMHO, virtual disk reduction help this problem?
Is there and engine config parameters that might help as well?
Thanks for any help on this.
