Hi all

I've currently got a reservation for 8 c6620 nodes at Cloudlab Utah -- only 2 are in use at the moment, and creating more experiments gives an error saying not enough are available.

I was able to use all 8 earlier in the same reservation, but now some (eg, er087) are not being allocated despite being in state FREE_CLEAN. I terminated the earlier experiments using the Portal API, which may have contributed to the issue. I normally create experiments via the Portal API but attempting to create it through the web interface does not have an impact on the error I'm seeing.

Any help is appreciated.

Thanks
Sam

Hi Sam,

A node went out of service unexpectedly, putting us into overbook.  I'll clear it up and let you know when we're good again.

Thanks,

We should be out of overbook now, try again.
