Clear fmadm or FMA fault logs

If the System Administrator doesn't have log rotation setup, logs fill up on the server from time to time. Usually the system or audit logs are the root cause, but sometimes the Fault Management Architecture (FMA) logs are the cause. On Solaris or if installed on Linux, there is a utility called fmd (Fault Manager Daemon) that checks for issues with the system hardware. This program is managed by the fmadm program. Follow the steps below to clear out the logs.

Clear error fmadm reports

root@earth> fmadm repair  UUID

The UUID is the event code that is shown when you run the fmadm faulty command.

* Note: If the above command doesn't clear the error then, there is a real issue hardware that needs to be addressed.

Clear reports and resource cache

root@earth> cd /var/fm/fmd
root@earth> rm e* f* c*/eft/* r*/*

Clearing out FMA files without rebooting.

root@earth> svcadm disable -s svc:/system/fmd:default
root@earth> cd /var/fm/fmd
root@earth> find /var/fm/fmd -type f -exec ls {} \;
root@earth> find /var/fm/fmd -type f -exec rm {} \;
root@earth> svcadm enable -s svc:/system/fmd:default
