This article is to share with you about what the on-fail parameter of CRM resource manipulation means. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

First of all, it's clear that the default value for on-fail is stop, so in some cases you don't have to configure it.

On-fail: the action performed when the current operation fails. Allowed values:

Ignore: pretend that the resource did not fail.

Block: no further action is performed on the resource.

Stop: stop the resource and do not start it in another location.

Restart: stop the resource and restart (possibly on a different node).

Fence: the node that failed to close the resource (STONITH).

Standby: removes all resources from the node where the resource failed.

When a STONITH device or block otherwise is configured, the default value for stop on-fail is fence, and the fence operation is performed. For other parameters, the default value for on-fail is restart.

As described in the pacemaker 1.1 configuration manual, the default is restart.

According to the pacemaker 1.0 configuration manual, the default is stop, and the latest default operation after testing is also restart, so the documentation should not be updated.
