Re: [Xen-users] xentop --vbds output?
> What does "OO" mean in the `xentop --vbds` output?
I believe it refers to the number of times that VBD has encountered an "out of
requests" error which has resulted in IO requests for that VBD being delayed.
The pending request structures are a global resource, so I'd say it's likely
if you see these going up for one VBD they'll also go up for others.
I guess it's likely to be caused by some combination of (relatively) slow disk
IO from dom0 and large numbers of requests coming from the VBDs of your
domains.
Cheers,
Mark
