Yesterday evening I have found the service responsible for the reboot instead of the powerdown. If I do: service wdmd stop the server will reboot. It seems the watchdog is hung up and eventually this will lead to a crash and thus a reboot instead of the shutdown.
Anyone knows how to debug this?
Did you get anywhere with this? Pretty nasty. Is there a bug open?
We're getting a timeout on an NFS mount during the powerdown (single-node hosted, after global maintenance enabled and engine powered off), and that makes the machine reboot and try to come back up again instead of powering off.
So two issues: - What is the mount that is hanging (probably an oVirt issue)? Don´t know what that problem is. I have a local nfs mount but don´t experience that problem
- Why does the system reboot instead of powering down as instructed (?)?
the reboot is caused by wdmd. Docs says that if the watchdogs aren´t responding that a reset will follow. So our init 0 is overruled because of the hanging watchdog. Why it is hanging I don´t know. Could be my chipset, could be the version of wdmd-kernel. Only thing is I know it didn´t happen always in the past but that is as much as I remember, sorry. Joop
