[one-users] Manually correcting ACPU ?

Hi,
we have a mid-sized cluster running ONE-3.0
on top of Ubuntu 11.10. We have several cases
where the ACPU calculation is in an inconsistent state.
ID NAME RVM TCPU FCPU ACPU TMEM FMEM AMEM STAT
32 node-blc17 3 2400 164 -1600 94.6G 27.8G -35014 on
It should be
TCPU - ( sum of all running VCPU )*100
on this host, and definitely not negative...
Note that the onehost list shows STAT=on, while onehost show (see below)
still shows confusingly the error from earlier this afternoon.
Question(s):
How Do I manually sanitize the ACPU count on this host ?
We're using mysql. I only found the "Database Schema for Accounting",
but no documentation for the "normal" schema. In which table
do I have to change what ?
It would be a good feature if a re-calculation of ACPU
could be triggered, based on all VMs currently allocated to this host.
Any idea how that could have happened in first place,
so we can avoid it in the future ?
Yours,
Steffen
