Use Direct Attached Storage (JBOD)

This topic describes how to configure the DAS-JBOD as the block storage backend provider for the Storage Controller (SC).

Prerequisites
To configure DAS-JBOD block storage for the zone, run the following commands on the CLC
  1. Configure the SC to use the Direct Attached Storage for EBS.
    euctl ZONE.storage.blockstoragemanager=das
    The output of the command should be similar to:
    one.storage.blockstoragemanager=das
  2. Verify that the property value is now: 'das'
    euctl ZONE.storage.blockstoragemanager
  3. Verify that the SC is listed; note that it may be in the broken state:
    euserv-describe-services --filter service-type=storage
  4. Set the DAS device name property. The device name can be either a raw device (/dev/sdX, for example), or the name of an existing Linux LVM volume group.
    euctl ZONE.storage.dasdevice=DEVICE_NAME

    For example:

    euctl one.storage.dasdevice=/dev/sdb
Your DAS-JBOD backend is now ready to use with Eucalyptus.
