This topic describes how to configure the DAS-JBOD as the block storage backend
provider for the Storage Controller (SC).
Prerequisites
- Successful completion of all the install sections prior to this section.
- The SC must be installed, registered, and running.
- Direct Attached Storage requires that
/var/lib/eucalyptus/volumes have enough space for
locally cached snapshots.
- You must execute the steps below as a Eucalyptus administrator.
To configure DAS-JBOD block storage for the zone, run the following commands on the CLC
-
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
-
Verify that the property value is now: 'das'
euctl ZONE.storage.blockstoragemanager
-
Verify that the SC is listed; note that it may be in the broken
state:
euserv-describe-services --filter service-type=storage
-
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.
