"db_root" continuous lines

Hi, I have the console and dmesg output of one node full of this lines (one every few seconds), is it something I have to worry about ? Thanks.

db_root: cannot be changed: target drivers registered

can you list output of

dpkg -s petasan | grep Version
uname -r
dpkg -s targetcli-fb

Sure, here it is:

root@petasan04:~# dpkg -s petasan | grep Version
Version: 2.8.1
root@petasan04:~#
root@petasan04:~# uname -r
4.15.0-161-generic

root@petasan04:~# dpkg -s targetcli-fb
Package: targetcli-fb

You have an incorrect kernel 4.15. Any idea how you got this and how you are booting from it ?  Your best action is to configure the grub menu to boot from the PetaSAN supplied kernel.

 

Yes, you're right, the grub default had been changed, I'm afraid during my attempts to fix the grub issue described in this thread.

Now I restored the petasan kernel as grub default boot entry and the db_root error has disappeared, but the grub bootloader hasn't been fixed during the update to Petasan 2.8.1. Now any further attempt says that everything is up to date. Is there a way to manually apply the "bug fix for grub bootloader" also to this node ?

Thanks, Dk.
