Hello guys.
I installed version 5.0.15-0 to evaluate Rockstor. I installed it on three different physical servers: DELL R620, R440 and M630. In all cases the installation went smoothly, but always with the same error: Failed to Start Network Manager Wait Online.
I ran the commands zypper refresh and zypper up --no-recommends then restarted the servers. The problem persisted. Only after restarting the services (systemctl restart NetworkManager-wait-online.service and systemctl restart rockstor) was I able to complete the installation.
I hope this information can contribute in some way to the project;
@clemylton welcome to the Rockstor community. Thanks for sharing your experience on varied hardware.
You are correct, the Network Manager is a pre-requisite for Rockstor services to start successfully. The symptom you’re seeing is often time related to systems that have multiple NICs installed, and for some reason one of them takes too long to come up and report it back to the Network Manager Wait Online service, leading to a timeout and the consequences you’ve observed. There does not seem too much that can be done about it (aside from restarting the network manager and then subsequently Rockstor) at this time.
In the future there will hopefully be a better way to circumvent this limitation (e.g. systemically identifying if at least one Network interface is up, or something similar).
