mysqld stays alive after logging out

I've got problems with my hfs+ /home partition. So it seems to be unmounted dirty.

I can umount it safely, but for now i do it like this...

- logging out (KDE)
- logging in as root (TTY)
- then i have to pkill mysqld, 'cause lsof /home shows me, that its still alive and strangely the USER is my normal USERNAME, also i logged out before (KDE)
- then i umount my /home parition
- finally i can reboot with a clean hfs+ partition

So, to me it seems like mysqld stays alive when i reboot normaly via KDE and so the drive can't be umounted proberly.
Could this be right?
Is it normal, that there are akonadi related mysqld tasks still alive, also i logged out via KDE? Could someone please try?

I personally think that lsof /home should have no entries when no user is loged in...

Re: mysqld stays alive after logging out

To be more precisely, lsof /home looks something like this

akonadi_c  9888 markus  cwd    DIR    8,3        93     88 /home/markus

Re: mysqld stays alive after logging out

Oh, I think it makes more sense now I believe that mysqld runs on background as a daemon, so it's normal that it won't terminate after you log in/out...

Re: mysqld stays alive after logging out

So, when its normal then this could not be the reason for why my home partition is dirty, after a normal shutdown?

Re: mysqld stays alive after logging out

I would expect, that mysqld would be terminated on reboot or shutdown, also all partitions should be unmounted automatically, at least I would think, that that was systemd's job.
