Trouble shutting down a linux machine
I am having issues with my linux machine running openSUSE MicroOS. It runs fine but I can't power it off via SSH. I tried shutdown, poweroff and halt but no command turned the machine off. I then have to physically push the power button but I don't feel comfortable doing that too often because I might interrupt some processes which are still running? Is there something I could still try or something I did wrong?
You're viewing a single thread.
Did you use any arguments with shutdown? Does shutdown spin down the system, but not turn off the hardware, or does it not do anything? You can try " shutdown now -h". That should halt the system after a graceful shutdown.
I tried that now. It's still running but I can't access it via SSH.
Sounds like that shutdown the system, so the problem is just getting it to power off. You could try "halt -p”. That explicitly calls for the system to power off. If that doesn't work, perhaps try "halt -verbose", which will give a bunch of info on the next boot about what halt was doing, might show an error there that could you lead you in the right direction.
Will that show the info only when I connect a screen directly to the machine? Or also when I log into it with SSH the first time after the reboot?
I would think it should be in the boot log, but I am unsure on that one.
