Purpose

There is an unusual amount of used space in the pool of a replication source system and you want to determine if there are old defunct replication snapshots on the system.

To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - Disk Storage ZFS Storage Appliance Community

Troubleshooting Steps

Examine the amount of space being used by each project.

In the BUI in shares select "Projects". This will display the amount of data.

If any one project or share seems to be taking up more space than it should, select that project or share. Note that replication can take place on a project level or a share level.

Select Snapshots.

Examine each of the snapshots that begin with ".rr"

NAME CREATION UNIQUE TOTAL
.rr-77b32939-c6ed-6b98-89d3-e1951d98cab9-2 2011-5-15 08:42:12 0 2.54M

If the unique size is quite large, that means that the data in the snapshot from the last replication action is different from the current data.

Check the Creation date of the snapshot, if it is very old, you may have to destroy it.
