I am trying to obtain VMs on TACC site with minimal resources; 2 cores, 8GB RAM and 10GB hard disk. However, the slice submission always fails with:
Slice Exception: Slice Name: Traffic Listening Demo TACC, Slice ID: 30f9fb42-37be-420f-899e-082a41bfb735: Slice Exception: Slice Name: Traffic Listening Demo TACC, Slice ID: 30f9fb42-37be-420f-899e-082a41bfb735: Node: TACC_node4, Site: TACC, State: Closed, Insufficient resources : [disk]#
Even if I submit the slice with a 1GB hard disk request, it fails with the above error. Can someone explain what this error means and how to fix it ?
Hi Nishanth,
The error
Insufficient resources : [disk]implies that there is not enough disk available on the host on which your VM is being requested. Looking at your slice, following VM requesting a ConnectX5 is being rejected as it maps totacc-w4There is not enough disk available ontacc-w4to accomodate your VM hence the failure.

Thanks, so it does indeed stand for disk space.
When I look at the graphical stats on the Fabric Portal, it mentions that TACC has 103263/107463 GB free (it may not be the latest info, but I don’t think it varies by much). How can I ask Fabric to assign my VM on an underlying server where there is enough hard disk space ?
Portal currently display overall site TACC disk usage which is combined disk space on all the hosts at TACC. Control Framework determines possible candidate nodes for your VM on the basis of the resources requested.
Your slice is requesting for a VM with CX5, which in case of TACC are only available on
tacc-w4and hence it is trying to allocate it ontacc-w4but fails due to no disk space. I would recommend using a different site than TACC.Also, we are working on improving the Resource Usage display to show per Host level information.
Thanks,
Komal
