"unable to create db file" warning if the device is normally placed in a subdir (input, devmapper, etc.)

[Fabio Massimo Di Nitto]

Hi Scott,

i just noticed a new warning (at boot) with the latest ubuntu4 udev in feisty:

udevd-event[2365]: udev_db_add_device: unable to create db file '/dev/.udev/db/class@input@mice': No such file or directory

The machine has a ps2 mouse, but doesn't have X or anything.. just a small server.

There is also another one that happens more randomically that udevd-event fails to rename interfaces around. It seems that there is a race from the interface to appear and udev trying to give it the proper name. At the end of the boot everything still looks fine.

I have the same warning about "/dev/.udev/db/class@input@mice" plus one about "/dev/.udev/db/class@input@input1@mouse0".

I also have this:

add_to_rules: DRIVER== This will change in future release, please use DRIVERS== in /etc/udev/rules.d/65-persistent-disk.rules:11

and

add_to_rules: do not reference parent sysfs directory directly, that may break with future kernel, please fix it in /etc/udev/rules.d/65-persistent-disk.rules:12.

In addition to getting the warning, the mouse is not useable. Xorg places the pointer in the middle of the screen and it won't move/can't be used.

I also noticed that hald is eating my system resources. Not sure if that is related to this.

I am using kernel 2.6.20-2 when I get this.

[Fabio Massimo Di Nitto (fabbione)]

Derek that is a different bug. Please file another one and assign it to either X or kernel.

I can confirm this:

udevd[4403]: lookup_group: specified group 'nvram' unknown
udevd-event[4448]_ udev_db_add_device: unable to create db file '/dev/.udev/db/class@input@mice': No such file or directory

The mouse works, in the end.

As for my other problems see bug 74059. ;)

[Allcolor-g (allcolor)]

As confirmed by others

[Victor Noël (victornoel)]

i can confirm it too.

i get :
udevd[4403]: lookup_group: specified group 'nvram' unknown
udevd-event[4448]_ udev_db_add_device: unable to create db file '/dev/.udev/db/class@input@mice': No such file or directory

and for the mouse, i just have a touchpad on my laptop. (and it works well of course :)

[grazie (grazie-deactivatedaccount)]

Confirmed on xubuntu feisty herd 3 candidate daily release 01/02/07.

udevd[2315]:lookup-group: specified group 'nvram' unknown
edevd-event [2394]: udev_db_add_device: unable to create db file '/dev/.udev/db/class@input@mice': No such file or directory
edevd-event [2651]: udev_db_add_device: unable to create db file '/dev/.udev/db/class@input@input0@mouse0': No such file or directory
edevd-event [2663]: udev_db_add_device: unable to create db file '/dev/.udev/db/class@input@input3@mouse3': No such file or directory

Upgraded udev from 103-0ubuntu5 to 103-0ubuntu6 which required an dependancy upgrade to volumeid (same versions) which resulted in updated /boot/initrd.img-2.6.20-5-powerpc. On reboot the following additional messages where output prior to ones above

kinit: name_to_dev(/dev/disk/by-uuid/56f34625-d45b-4738-a776-2fad65e7c6b7) = hda4(3,4)
kinit: trying to resume from /dev/disk/by-uuid/56f34625-d45b-4738-a776-2fad65e7c6b7
kinti: No resume image, doing normal boot...

[R Morrison (rmorrisonva)]

nearly the same symptoms as everyone else. running feisty 7.04 all repos enabled on amd64 (ubuntu arch: amd64) .

[Jaakko Heinonen (jheinonen)]

Confirmed. Getting these errors after minimal install from alternative CD.

[rasz (citizenr)]

same here

where do you find this? I mean where is uved logging this shit? I searched an hour, even tried enabling logging in udev (from err to debug) an still couldnt find the log :(

[Brian Fallik (bfallik)]

For me, I see this msg logged to the console during startup.

(transcribing during an fsck on boot)
  udevd-event[2623]: udev_db_add_device: unable to create db file
'/dev/.udev/db/class@input@mice': no such file or directory

Hope that helps.

I know its in the console - I saw it there :P, Im asking where udev saves its logs

[Brian Fallik (bfallik)]

Running "sudo /etc/init.d/udev restart" produces the same error
messages in /var/log/syslog.

thank you,
so shouldnt udev save the log to syslog at boot too?

[Brian Fallik (bfallik)]

Perhaps udev starts before syslog? It appears that, in either case,
udev is logging the same information. I'd guess that perhaps syslogd
isn't ready/listening so the msgs are echoed to the console during the
initial boot.</wild guess>

[rasz (citizenr)]

latest update fixes it for me
