Hi!  
When I try to add or activate a host (the only available and freshly installed OpenNebula system) i get the following error:

ERROR: Mon Jan 28 17:27:38 2019 : Error monitoring Host cloud1 (1): Timeout executing ‘if [-x “/var/tmp/one/im/run\_probes”]; then /var/tmp/one/im/run\_probes kvm /var/lib/one//datastores 4124 60 1 cloud1; else exit 42; fi’

I tried to run the following command as oneadmin without any issue: “/var/tmp/one/im/run\_probes kvm /var/lib/one//datastores 4124 60 1 cloud1”

See output from the above command bellow:

Fixed by editing the /etc/one/oned.cfg and removing the double slashes from datastore path: /var/lib/one//datastores

Don’t know how that did end up there.
