Mageia 5 - ownership changes to "nobody" after KDE login

[macxi]

Hi,
1 - I did a clean install Mageia 5 DVD (classic) KDE, 64, a physical machine, with grub boot (no grub2 and without UEFI).
2 - After installing, I set up the media, updated and then installed about 40-50 applications listed in the post installation tips (see topic Mageia 2 - Configuration tips after installing Mageia). Everything worked perfectly.
3 - When I restarted the machine, appeared to the user list, but was unable to access KDE with the common user, I had created. The KDE desktop environment not opened and the warning:

"Call to lnusertemp failed {temporary directories full?}. Check your installation?"

.

I could access the common user-graphical environment IceWM and saw that the owner of the common user folders became the "Nobody".

Dolphin accessed as root, and fix the owner of folders.
But because restarting a few times, the error was repeated.

So I opened the bug 16420.

Then I saw that the error was repeated in other partitions with the Mageia 3 installed
What can this be?
Does error in HD can cause change in the owner?

Note: the same topic in forum Mageia of Brasil

Check the /home/username folder for the affected user, and also check / and /tmp sizes and free space via df -h
See also the comments for the same issue in an old bugreport: https://bugs.mageia.org/show_bug.cgi?id=978#c12
and also http://tech.anoj.net/2008/10/call-to-ln ... dding.html

Please also create a new user, and try to reproduce with that user.

doktor5000,
I've created a new user
It seems to me that does not have any error in Mageia 5. It seems to me that the error was caused because the home partition was full.
I checked with the KDF and saw that the / home partition was 100% full, despite having 1GB of free space.
I'm still checking it. I've got 20GB of free space on the / home partition.
I'll check if the error is repeated and notice here.
thanks

The same error still occurs:

When the user's owner change for nobody/nogroup, if I try to access the user, an error message appears::

"Call to lnusertemp failed {temporary directories full?}. Check your installation?"

To fix, I access a terminal as root and type:

chown -R mageia5:mageia5 /home/mageia5
or
chown -R mageia3:mageia3 /home/mageia3

So I restart the computer and access the user

The same error still occurs:

Code: Select all

[root@localhost ~]# ls -al /home
drwxr-x--x 31 mageia5 mageia5        4096 Nov  8 08:13 mageia5/


To fix, I access a terminal as root and type:
chown -R mageia5:mageia5 /home/mageia5

This doesn't make much sense, it already had owner and group as mageia5, see above in your output.

Question is, how do you access that /home partition, seems also from other Mageia versions.
Is it maybe also exported via NFS at some time? As the UID and GID for nobody:nogroup would be 65535, which seems really strange,
as nothing usually changes the ownership of folders in /home.

You should also be aware about the different default UID/GID in Mageia 5 compared to previous Mageia versions.
This is briefly mentioned in release notes. Since Mageia 5, new users are created starting with UID >= 1000, previously UID >= 500 was used.
This is important if you also want to access folders from a different distro.


Please also provide the output of

Code: Select all

ls -aln /home

so we can see the numerical user IDs used.

FWIW, to me the ownership of /home itself and / with root and group adm also looks strange, that's not the default.

This computer is a Notebook. Currently it has five partitions: Win, home, mageia3, mageia5 and swap.
The Mageia2 and Mageia4 aren't installed

With the situation shown above, I can access the Mageia5 without problem. But if I try to access the Mageia 3, I'll have to type the command: chown -R mageia3:mageia3 /home/mageia3
If I linger a long time using Mageia3, can occur changes Mageia5 ownership to "nobody".
.
As soon as I can, I will update the "Mageia 3" to "Mageia 5" and see if this error continues to happen
