[SOLVED] Fedora 27 slow boot...

ddenial · 04-03-2018, 02:21 AM

Hello

My Fedora 27 boots very slow. While booting, when it reaches 'Starting Switch Root', it takes almost 30+ seconds and then login screen appears.

I had installed CentOS 7.4 and Ubuntu 17.10 on the same machine earlier, and have noticed this problem doesn't exist on those OSs. Its only for Fedora Workstation.

These are my systemd-analyse results.

Code:

Startup finished in 8.743s (firmware) + 1.297s (loader) + 883ms (kernel) + 2.704s (initrd) + 33.739s (userspace) = 47.367s
         22.434s udisks2.service
          9.876s NetworkManager-wait-online.service
          6.444s firewalld.service
          5.958s lvm2-monitor.service
          5.273s dev-mapper-mdd\x2dsvr.device
          4.675s systemd-udev-settle.service
          4.323s sssd.service
          3.962s initrd-switch-root.service
          3.479s libvirtd.service
          3.358s jexec.service
          3.316s ModemManager.service
          2.997s polkit.service
          2.892s fwupd.service
          2.567s named.service
          2.180s switcheroo-control.service
          2.177s gssproxy.service
          2.173s sysstat.service
          2.173s livesys.service
          2.173s named-setup-rndc.service
          2.063s avahi-daemon.service
          2.054s accounts-daemon.service
          2.012s systemd-journal-flush.service
          1.624s abrtd.service
          1.597s systemd-udevd.service
          .
          .

So delay is from udisks2.service, I assume.

Code:

# systemd-analyze critical-chain udisks2.service

The time after the unit is active or started is printed after the "@" character.
The time the unit takes to start is printed after the "+" character.

                              └─system.slice
                                └─-.slice

This is my fstab

I've checked UUIDs are correct.

Why udisks2.service takes so long? Or is this normal?

Thanks

Check the journal. On this crappy 8 year old i7 laptop, udisks2.service took 1.211s on my last F27 boot.

Nothing in there.

Code:

# journalctl | grep -i disk | grep -Ei 'fatal|error|warn|fail'

What DE are you running?

I changed DefaultTimeoutStartSec and DefaultTimeoutStopSec to 10 seconds, and now the udisks2.service is reduced to 2.986 seconds from whopping 22.434 seconds. This is a great improvement. Thanks.

Code:

$ systemd-analyze blame | grep udisks2
          2.986s udisks2.service

But surprisingly, physical boot time is still same - has not reduced. Strange!!!

Code:

$ systemd-analyze
Startup finished in 8.749s (firmware) + 1.132s (loader) + 875ms (kernel) + 2.723s (initrd) + 33.112s (userspace) = 46.592s

You're Welcome.

Gnome isn't as much of a RAM hog as KDE so I don't think it's the DE.

Yeah, it is strange that the boot time is still the same.

When you have the time look in the Fedora Forums there might be a way around it:-
Good Luck

Sounds pretty normal for Fedora.

Thanks, everybody. Going back to CentOS 7.4. I'll try i3 Window Manager this time.
