perfSONAR User Q&A and Other Discussion

[Jonathon A Anderson <>]

Looks like regular_testing (and likely other services?) can’t start because 
it can’t create a pidfile in /var/run.

selinux is disabled, permissions look fine (the same as on a working 
perfsonar box, anyway) and the disk isn’t full.

Any thoughts on why pidfile write might be failing?
