If you don’t use lvm partitions, just disable this service.

sudo systemctl disable lvm2-monitor.service


ok thanks Fred

Tried that, even rebooted no change. Pretty sure not using LVM.

for those you cannot use disable… only activity will stop if you do sudo systemctl mask lvm2-monitor.service


Exactly … because using disable doesn’t stop it from restarting but mask does.


[bob@Endeavour ~]$ sudo systemctl mask lvm2-monitor.service

Ouch! I always forget this systemctl feature :frowning:

well the masking solution worked but there were other problems so I did some more looking around the forum and found someone suggested a reinstall which I decided to do,this install no problems so thanks for the help folks,your suggestions helped ,but I decided on a clean install to see if the bug returned,it did not but also I had fedora installed on another hard drive so I uninstalled it because the home partition was lvm so maybe thats where my problem was coming from once again thanks
kind regards Ron
ps bye the way the system is very good

just a side notice, if you decide to stop Mask with systemctl , it can be happend you made a fault on this, you can always chroot into the system and fix it like sudo systemctl unmask XXXX.service
