Overview

The Blocklets File Store (BFST) is the blockpool. Blockpool corruption could bring down the system, cause data loss, performance issues, failed backups and/or restores, and many other issues. Service/Support needs to understand how this all works, what processes make up the blockpool, and the location/name of log files and configuration files. You must also be able to recognize blockpool problems, and how to troubleshoot and fix these problems.

Files

Binary: /opt/DXi/blockpool/bin/blockpool
Repository: /snfs/blockpool/

Ways to Start / Stop the Blockpool Process

Dependencies same as before – SNFS, and now pcache (BPW)
Start in the usual way: /etc/init.d/blockpool

Location of Log Files

Same as before - /var/log/blockpool_master.log
Increase verbosity with blockpool set +FLogFileSeverity=Information +Nlocal@localhost

Notes about Blockpool Configuration Files

• Configuration is the same between DXi 1.x and DXi 2.x software.
• Platform settings have not changed. They are still in here: /opt/DXi/blockpool_settings.txt.
• Server configuration is located here: /opt/DXi/blockpool_config.txt. Generally, there's isn't a need to ever alter anything without engineering involvement.
• The new platforms use different settings names (such as kahlua24GB_v2.0 vs. the old kahlua24GB).
