Booting problem

[satimis]

Hi all,

Ubuntu 18.04 desktop

On booting following warning popup

fail to connect lvmetad falling back to device scanning
....


It waits for long time but finally it boots

What is the warning?

I couldn't find this warning on /var/log/boot.log ?

It means the lvm daemon is not started yet. This happens when the root system or especially /boot is in a logical volume and needed to continue startup. It doesn't mean anything much. You might be able to eliminate it by forcing lvm2 to start sooner.

When you say it waits a long time who long are you seeing. I have several systems set up this way and there is a wait but it isn't that long

Hi,

Thanks for your advice.

Just checked it. The waiting time is about 45 sec after the warning.

Ubuntu 16.04 doesn't has this symptom. It only waits about 4~5 sec after the warning.

I haven't upgraded to 18.04 yet so I'm still running 16.04 LTS. Are your root and or boot on a logical volume? If so I'd consider filing a bug. 45 seconds is a long time. especially since 16.04 only takes a few seconds.

It is raw installation on ubuntu-18.04-desktop-amd64.iso, not upgrade. It seems the newly published Ubuntu-18.04 desktop is not very stable. There are some other issues and you'll find some links on Internet complaining this version.

I'll cease testing Ubuntu 18.04 until it become stable.

I run the LTS version on several machines. I never upgrade them until the .1 version, that's also the first point at which a automatic upgrade is offered by Synaptic.
