Re: starcluster plugin status code 127

Hi Don,

The plugin picked up the queue_to_config (all.q) as evidenced in the error
message:

!!! ERROR - command 'qconf -mattr queue load_thresholds np_load_avg=1.5 *
all.q*' failed with status 127

My intention is to config the SGE at the cluster boot up time using the
plugin. Since I executed "starcluster runplugin" after the cluster already
booted up, it apparently is not an issue of plugin execution timing.

The only reason I run the plugin or the plugin command after cluster
already booted up is for debugging purposes.

It's just very strange to me that as root I can execute the exact same
command on the master node without any issue, but running as starcluster
plugin would fail.

Also, what is status 127 anyway??

Thanks!

-Wei
