Hi All,

I have a Fedora 27 server out there that won't poweroff or reboot properly. When told to power off or reboot, it gets to the point where it seems that everything is terminated, but it won't throw the power switch or the reboot command. The keyboard is locked up so tight that your can not even toggle the num lock key. No keystroke is effective. To boot back up, you have to pull the power cord.

I turned off the "f" splash screen to see what the last thing it showed was:

mount: /oldsys/sys: file system was mounted, but any subsequent operation failed: permission denied
mdmon: error connecting monitor with run/mdadm/md127.sock: permission denied
dracut Warning: killing all remaining processes

The last thing I see with "# journalctl -b -1 | tail" is:

Jan 15 19:55:09 systemd[1]: Reached target Shutdown.
Jan 15 19:55:09 systemd[1]: Reached target Final Step.
Jan 15 19:55:09 systemd[1]: Starting Reboot...
Jan 15 19:55:09 systemd[1]: Shutting down.
Jan 15 19:55:09 lvm[2963]: /run/lvm/lvmetad.socket: connect failed: Connection refused
Jan 15 19:55:09 lvm[2963]:   WARNING: Failed to connect to lvmetad. Falling back to device scanning.
Jan 15 19:55:09 systemd-shutdown[1]: Sending SIGTERM to remaining processes...
Jan 15 19:55:09 systemd-journald[665]: Journal stopped

I am tempted to place this on the bugzilla, but as it could be a tech support issue, I don't want to get the finger shaken at me.

Many thanks, -T

It looks like you have some filesystem mounting issues. What is at /oldsys/sys? Also, why is it complaining about md127? Check the earlier logs to see if you can get any further info on that.

I can not find /oldsys/sys anywhere. It does not show in "mount" or fstab. "# find / -type d -iname oldsys" returns nothing. What the heck?

no idea. I see it in the log, but ...

# lsblk --list
sda       8:0    0 894.3G  0 disk  
sdb       8:16   0 894.3G  0 disk  
sdc       8:32   0 894.3G  0 disk  
sdd       8:48   0   1.8T  0 disk

md126p4 259:3    0 832.7G  0 md    /

I wonder if md127 has anything to do with oldsys?

Any word of wisdom?
