GPFS log files
IBM® General Parallel File System (GPFS™) log files are updated during IBM Storage Protect Snapshot, or IBM Storage Protect Snapshot Custom Applications operations.
The GPFS log files are in /var/adm/ras directory on each GPFS node, and start with the prefix mmfs.log. The most current GPFS log file can be found by using the symbolic link /var/adm/ras/mmfs.log.latest. See the information about GPFS log files and troubleshooting procedures in the IBM General Parallel File System (GPFS) for Clusters: Problem Determination Guide (GA76-0415-08).
