[one-users] Manually correcting ACPU ?

[Steffen Neumann]

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
