5.2.2. Linux Standard Base

LSB resource agents are those found in /etc/init.d.

Generally they are provided by the OS/distribution and, in order to be used with the cluster, they must conform to the LSB Spec. ^[11]

Many distributions claim LSB compliance but ship with broken init scripts. For details on how to check if your init script is LSB-compatible, see Appendix G, init-Script LSB Compliance. The most common problems are:

Not implementing the status operation at all
Not observing the correct exit status codes for start/stop/status actions
Starting a started resource returns an error (this violates the LSB spec)
Stopping a stopped resource returns an error (this violates the LSB spec)

^[11] See http://refspecs.linux-foundation.org/LSB_3.0.0/LSB-Core-generic/LSB-Core-generic/iniscrptact.html for the LSB Spec (as it relates to init scripts).
