DataKeeper Resource
Field Tips
Bitmap File
Select the bitmap file entry from the pull down list.
Displayed in the list are all available shared file systems that can be used to
hold the bitmap file. The bitmap file must be placed on a shared device that can
switch between the local nodes in the cluster.
Important: The bitmap file should not reside on a btrfs filesystem. Placing data
replication bitmap files on a btrfs filesystem will result in an "invalid argument"
error when LifeKeeper tries to configure the mirror. The default location for the
bitmap file is under /opt/LifeKeeper. This default location should be
changed if /opt/LifeKeeper resides on a btrfs filesystem.
4. Click Next to create your DataKeeper resource on the primary server.
5. LifeKeeper will verify that you have provided valid data to create your DataKeeper resource. If
LifeKeeper detects a problem, an ERROR will appear in the information box. If the validation
is successful, your resource will be created.
Click Next.
6. An information box appears announcing that you have successfully created an existing rep-
licated file system resource hierarchy. You must Extend the hierarchy to another server in
your cluster to begin replication and to place it under LifeKeeper protection.
Click Next to extend the resource, or click Cancel if you wish to extend your resource at
another time.
If you click Continue LifeKeeper will launch the Pre-extend Wizard. Refer to Step 2 under
Extending Your Hierarchy for details on how to extend your resource hierarchy to another
server.
DataKeeper Resource
This option will create only the NetRAID device (not a file system) and place the device under
LifeKeeper protection. You should select this option if you only want to create a DataKeeper device
on a disk or partition and place the device under LifeKeeper protection. You will need to manually
make and mount a file system on this device in order to create a readable mirror. You will need one
free disk or partition for this resource type.
