I am using NUT to shutdown the ups powering my CentOS 6 server but it has a 30 second delay when executing the shutdown.When I runupscI can see that the 30 seconds is controlled by the variableups.delay.shutdown: 30However when I try to change it usingupsrw -u upsmon -p upsmon -s ups.delay.shutdown=0 mecerThen I get the following errorERR READONLYWhy is this? If removing those 30 seconds is not possible then is it possible to just make the ups power off after 10min?
NUT upsrw ERR READONLY
ups;nut
