| 57 | * As a site admin: |
| 58 | * Browse to [https://boss.utah.geniracks.net/nodecontrol_list.php3?showtype=dl360] |
| 59 | * Login |
| 60 | * Enter red dot mode |
| 61 | * The white dots in the "Up?" column and lack of Name/PID/EID info show that pc1, pc2, and pc4 are available for experimenter use, and are not in use right now |
| 62 | * pc3 and pc5 are in use. Of these: |
| 63 | * pc5 is in an special experiment, `emulab-ops/shared-nodes`, and is running the OS `FEDORA15-OPENVZ-STD`. It's a reasonable guess that this is the OpenVZ shared node, which provides Fedora 15 VMs to experimenters. Browsing to [https://boss.utah.geniracks.net/showexp.php3?pid=emulab-ops&eid=shared-nodes#nsfile], corroborate that by finding the setting: |
| 64 | {{{ |
| 65 | tb-set-node-sharingmode $vhost1 "shared_local" |
| 66 | }}} |
| 67 | * pc3 is not special. It is an experimental node which is in use. |
| 68 | * Thus, a site admin can learn that the current allocation is 1 OpenVZ node, 0 !PlanetLab nodes, and 4 experimental nodes. |
| 69 | * As an experimenter, run: |
| 70 | {{{ |
| 71 | omni -a http://www.utah.geniracks.net/protogeni/xmlrpc/am listresources -o |
| 72 | }}} |
| 73 | and view the output. Learn the following things: |
| 74 | * the node entry for pc3 has a field showing it's unavailable (this is "true" for e.g. pc1): |
| 75 | {{{ |
| 76 | <available now="false"/> |
| 77 | }}} |
| 78 | * the node entry for pc5 contains these lines (10034 is the OSID for FEDORA15-OPENVZ-STD, though i don't know how you'd know that as an experimenter. But "pcshared" seems like a clue): |
| 79 | {{{ |
| 80 | <emulab:fd name="pcshared" violatable="true" weight="1.0"/> |
| 81 | <emulab:fd name="OS-10034" weight="0.5"/> |
| 82 | }}} |
| 83 | * also, the node entry for pc5 contains 49 slots of type "pcvm", whereas the other nodes contain 50. I bet that is a clue to how many VMs pc5 thinks it can run, since i have one VM allocated on there right now (that is, i bet pc5 thinks it can allocate 50 VMs): |
| 84 | {{{ |
| 85 | <hardware_type name="pcvm"> |
| 86 | <emulab:node_type type_slots="49"/> |
| 87 | </hardware_type> |
| 88 | }}} |
