Why is OpenSUSE Tumbleweed taking ages to boot?

English Install/Boot/Login
#1

Hi all,
recently installed openSUSE and I can say I am loving it! However I noticed that it is taking anywhere from 2-4 mins to boot. The first time I booted it after installation it took seconds (should note this is on an ssd) but now it seems to be taking forever. I havent done anyting but install steam and nvidia drivers and a few other programs. Here is the first 3 lines of my systemd-analyze blame output
Text
2min 3.902s btrfsmaintenance-refresh.service
2min 2.166s chrony-wait.service
1min 59s plymouth-quit-wait.service

I have no clue what these services are and why they are taking so long, please someone help!

If you inspect /etc/fstab, is btrfs present anywhere? If not:

 sudo zypper rm btrfs*

may be all you need to do. You seem to be describing https://bugzilla.opensuse.org/show_bug.cgi?id=1124823

You can use

systemctl cat chrony-wait.service

which will give you some information, and the relevant “man page”.

My system has:


erlangen:~ # systemd-analyze blame|head

    1min 46.299s mlocate.service
         25.745s backup-albums.service

          3.799s systemd-networkd-wait-online.service
          2.848s display-manager.service

           656ms apparmor.service

The above doesn’t matter. What really matters:

erlangen:~ # systemd-analyze critical-chain

When the machine stalls, click escape to get supplementary information from the splash screen.

Maybe a stop job is running?
