|Eucalyptus HA Installation / Configure Eucalyptus|
In order to start new instances, Eucalyptus needs a sufficient number of loop devices to use for SC and NC components. An SC with insufficient loop devices fails to create new EBS volumes. An NC with insufficient loop devices fails to start new instances.
Eucalyptus installs with a default loop device amount of 256. If you want to change this number, perform the following steps. Otherwise, skip this section.
