This is realy urgent. Wachting the behaviour of samba 4.19. It is filling tmpfs /run/lock/samba until 100%:
Dateisystem Größe Benutzt Verf. Verw% Eingehängt auf
udev 63G 0 63G 0% /dev
tmpfs 13G 2,4M 13G 1% /run
/dev/mapper/dommaster--vg-root 3,6T 17G 3,4T 1% /
tmpfs 63G 2,5M 63G 1% /dev/shm
tmpfs 5,0M 4,7M 324K 94% /run/lock <--- samba is filling
/dev/sda2 471M 150M 297M 34% /boot
/dev/sdb1 11T 3,4G 11T 1% /f2
/dev/sda1 511M 3,5M 508M 1% /boot/efi
tmpfs 13G 84K 13G 1% /run/user/116
tmpfs 13G 56K 13G 1% /run/user/1000
After a restart of samba service:
Dateisystem Größe Benutzt Verf. Verw% Eingehängt auf
udev 63G 0 63G 0% /dev
tmpfs 13G 2,4M 13G 1% /run
/dev/mapper/dommaster--vg-root 3,6T 17G 3,4T 1% /
tmpfs 63G 4,1M 63G 1% /dev/shm
tmpfs 5,0M 3,4M 1,7M 68% /run/lock <-- restarting samba set it back to work!
/dev/sda2 471M 150M 297M 34% /boot
/dev/sdb1 11T 3,4G 11T 1% /f2
/dev/sda1 511M 3,5M 508M 1% /boot/efi
tmpfs 13G 84K 13G 1% /run/user/116
tmpfs 13G 56K 13G 1% /run/user/1000
And then no logon or whatever is possible. I need to restart samba services before it has reached the 100 % peak
to set /run/lock/samba back to work.
How can I manage that? This was not the behaviour in former versions of samba.
Greetings
Daniel

I examined a bit closer. And samba writes to /run/lock/samba:
drwxrwxrwt 5 root root 120 5. Dez 2022 ..

-rw------- 1 root root 24576 11. Sep 09:58 smbXsrv_version_global.tdb
So my tmpfs in this case is:
tmpfs 5,0M 3,7M 1,4M 74% /run/lock <--------
I found a log entry "NT_STATUS_DISK_FULL" :

Could it be samba filled up the tmpfs? So the smbXsrv could not be changed and written anymore?
Can I stop samba and remove this tdbs?

Daniel

Dear all,
after updating to samba 4.19 I cannot use ADUC anymore:
Error Trust levels between the domain could not be established because of no domain server.

What I did after upgrading:
I set ad dc functional level = 2016 in smb.conf I did, samba-tool domain schemaupgrade --schema=2019 samba-tool domain functionalprep --function-level=2016 samba-tool domain level raise --domain-level=2016 --forest-level=2016
All was working over the weekend but suddenly crashes. Even the Emailserver cannot authenticate against the domain.
Kinit not possible:
kinit administrator at TLK.LOC
kinit: für Realm »TLK.LOC« kann nicht KDC kontaktiert werden bei Anfängliche Anmeldedaten werden geholt.
How can I fix this quickly!?
Greetings
Daniel
