Thread: System boots and shutdown slow

  1. #1

    Default System boots and shutdown slow

    I'm using OpenSuSE 13.1 with kernel 3.14.4-30.gbebeb6f-desktop . Filesystem of root is btrfs. I think culprit is filesystem of root. I also noticed system is checking filesystem of /home(ext4) on every boot. On default kernel of this release the problem also occur.

    I have checked system startup time and it was one minute 20 seconds. I don't have ssd hard drive. On virtual machine (VirtualBox) running on this same computer system starts very fast. System on virtual machine don't use btrfs as root filesystem.

    That in itself is not bad.

    Code:
    Telcontar:~ # systemd-analyze
    Startup finished in 13.365s (kernel) + 1min 32.088s (userspace) = 1min 45.453s
    Telcontar:~ #

    For all virtual machines, there is a bootup bug. Download and run the script I reference in the Forum thread in every Guest to fix.

    I've found this problem so far to affect VMware, VirtualBox and KVM. Probably affects "all" virtualization technologies.

    I don't know what Desktop you're running, if KDE then over a minute and possibly about a minute and a half for a new machine with relatively few services running can be expected. If you want to trim faster bootup times, try a different Desktop. My VMs typically shutdown within 15 seconds unless I have a very big app running which has to shut down gracefully.

    After moving from 13.2 to Tumbleweed my system boot in 37 seconds and shutdown very fast. This was true until yesterday. My system boots in one minute now. I checked systemd-analyze blame and it shows:

    I restarted my system many times and it boot in one minute all of time! Log shows, dev-sda1 (root filesystem of btrfs type) unit takes very long time. Maybe filesystem check? But this is not case - system boot in one minute every time!

    check the partition with the BTRFS utilities maybe run fsck on it too, check logs.

    I have performed defragmentation on my root and restart machine. My system now boots not in 1 minute 10 seconds, but in 52 seconds. But this is still not 37 seconds. What can I do? I decided to update dracut, but I haven't update anything before my system slows down.

    When system boot, there's many messages like :
    Code:
    systemd-udevd[402]: maximum number (136) of children reached
