I was having a strange problem whereby my new 15.4 Leap installation was refusing to shut down. I checked the shutdown logs and various forum suggestions here, none of which gave any clue or helped.
I later ran the Power Management setup and it reported that disk manager was blocking sleep screen locking mdraid-sync-job
And indeed checking this there was a very long RAID sync up going on between the two new drives.
Presumably this was blocking shutdown as well but I didn’t get any warnings on screen or anywhere in the logs while this was going on.
Once I’d allowed the sync to complete (several hours) then shutdown worked as normal.
I wasn’t expecting a long sync on two new drives, I don’t remember seeing this on previous RAID setups.
So anyway I get that preventing shutdown is correct behaviour but no notification of it anywhere completely threw me.
Should I open a bug for this?
