Logs

This topic describes various logs that are generated in the IBM Storage Scale.

GPFS logs
The GPFS log is a repository of error conditions that are detected on each node, as well as operational events such as file system mounts. The GPFS log is the first place to look when you start debugging the abnormal events. As GPFS is a cluster file system, events that occur on one node might affect system behavior on other nodes and all GPFS logs can have relevant data.
Audit messages for cluster configuration changes
As an aid to troubleshooting and to improve cluster security, IBM Storage Scale can send an audit message to syslog and the GPFS log whenever a GPFS command changes the configuration of the cluster.
Protocol services logs
The protocol service logs contain the information that helps you to troubleshoot the issues related to the NFS, SMB, and S3 services.
Operating system error logs
GPFS records file system or disk failures by using the error logging facility provided by the operating system: syslog facility on Linux®, errpt facility on AIX®, and Event Viewer on Windows.
Transparent cloud tiering logs
This topic describes how to collect logs that are associated with transparent cloud tiering.
Performance monitoring tool logs
The performance monitoring tool logs can be found in the /var/log/zimon directory on each node configured for performance monitoring.
File audit logging logs
All major actions performed in configuring, starting, and stopping file audit logging produce messages in multiple logs at varying degrees of granularity.
Active File Management error logs
Some errors occur during the replication. These errors impact the replication. You can check information about the errors that are logged in the /var/adm/ras/mmfs.log.latest file.
