Creating a queue. qmgr: cannot connect

Users/Site Administrators
1

I have a couple VM’s running Ubuntu 18.04 with OpenPBS 20.0.1 and Singularity 3.6.4. One is set up as a host server with the other setup as a compute node with the mom daemon enabled. I’m using LDAP for a naming service to eventually help this cluster manage users. This thread seems related https://community.openpbs.org/t/install-pbspro-on-a-single-node/1155/3

I’m looking for some advice on this error:
qmgr -c “create queue workq queue_type=e,started=t,enabled=t”Unknown Host.
qmgr: cannot connect to server queue
Unknown Host.
qmgr: cannot connect to server workq
Unknown Host.
qmgr: cannot connect to server queue_type=e,started=t,enabled=t”

Here’s some additional info:
qmgr -c ‘p s’
Unknown Host.
qmgr: cannot connect to server s’

Can you run this command and check the output
qmgr -c “print queue @default”

Also, please check these pre-requisites :

Is this another case where wiki quotes are being confused for computer quotes?

Run the commands again, but type them yourself instead of using copy/paste from the web. That is, make sure you use ' and ", not ‘ ’ and “ ”.
