Overview

You can check a blockpool verify in the messages log. A blockpool verify will check the integrity of the blockpool structure.

When you list the contents of the messages log, you should see the following sections (as worded below):

• Verify blob tree heap
• Index load
• Verify cluster tree
• Verify clusters
• Verify blob tree heap free list
• Verify blob tree data lists
• Verify blocklet lists 

You might suspect blockpool corruption in the following cases: 

• Replication status shows that replication has failed.
• A healthcheck failed, and blob are missing or corrupted.
• There was a power outage, and the unit does not boot up properly or SNFS is not mounting.
• There was a storage array issue, and SNFS is not mounting.
• There was a filesystem PANIC, and the unit is not responding.
• The unit is in a “hung” state.

You can check the Blockpool Verify status by running:

              /hurricane/blockpool/bin/blockpool status +Nlocal@localhost
