cc-snapshot

cc-snapshot takes snapshots of baremetal instances on the Chameleon testbed.

Dependencies

The script requires the following dependencies:

• Ubuntu or CentOS system
• Baremetal instance

Usage

Use this script from a Chameleon baremetal instance. To snapshot a baremetal instance, when logged into the instance via SSH, run cc-snapshot with the following command:

sudo cc-snapshot [snapshot_name]

You can optionally specify a snapshot name. If no argument is present, the snapshot name is set to the instance hostname followed by a universally unique identifier.

cc-snapshot will ask for your Chameleon password, and after a few minutes, a snapshot will be uploaded in the image repository of the instance's site (UC or TACC).

Troubleshooting

virt-customize: error: libguestfs error: lvs: lvm lvs --help: Invalid units specification

• Problem: the LVM2 package is incompatible with libguestfs (see https://bugzilla.redhat.com/show_bug.cgi?id=1475018)
• Resolution: update the lvm2 package. On CentOS:

  sudo yum makecache
  sudo yum update lvm2
