[opensuse] very long boot time (13.1)
![](https://seccdn.libravatar.org/avatar/d7a1abb38a8ed313081bb8f250b16199.jpg?s=120&d=mm&r=g)
Hi, always nice to run into new problems with every new openSUSE version, not. ;-) After unexpected smooth operation of 12.3 wrt systemd and boot/shutdown the 13.1 behaviour fell behind a decade again. Booting takes ages as well as shutdown. Since shutdown is hard to debug and I have not much information yet I'd like to ask about the boot phase. Hygiea:~ # systemd-analyze blame 33.536s systemd-udev-settle.service 3.163s network.service [...] There are some more in the area of 3 seconds but what is the first one doing? I guess basically nothing since with 12.3 I haven't had the issue and the system still worked? Can I make the "nothing" faster somehow? Or alternatively how to find the culprit there? Hygiea:/usr/lib/systemd/system # systemd-analyze time Startup finished in 4.886s (kernel) + 44.001s (userspace) = 48.888s Thanks, Wolfgang -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

systemd in 13.1 has nice boot/shutdown time animation for services that take too long. Disable plymouth, remove "quiet" from kernel command line and check which service is stalled. I suspect I know what it will be but let's wait for your results. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I had this with 12.3 :-! as far as I can understand it it comes from the network dhcp a bit to slow (from the server side) and had to wait. I now use a ssd disk and boot is extremely fast, but one thing (probably this same one) try typing ESC at boot time to see where the boot stalls, and may be then go to /var/log/message to see what is *after* the message that seemed to stall on the screen :-) jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

By the way, I just did a reboot. starting ifup is where it stalls, at second 17, and "reached target network" is only at second 38, may be partly in background, because it didn't seems so long jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

AFAIK udev-settle should not be used but it is anyway used by this lovely thing called LVM, this is currently the only service pulling it. Even more, it is not guaranteed to work correctly with LVM at all, currently falling in the category of "dirty hack". -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Hmm, I don't use LVM on that machine. I use mdraid though but this hasn't changed during the last years. I still need to try Andrey's suggestion. Wolfgang -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
