Hi after changing the right on some /var/lib/centreon/centplugins .

It’s seams that I have a new trouble:

 

## Right on FS

as centreon-engine

bash-4.4$ ls -l /var/lib/centreon/
total 348
drwxrwxr-x.  2 centreon        centreon             6 Sep 26 09:10 centcore

bash-4.4$ chown centreon:centreon /var/lib/centreon/centplugins
chown: changing ownership of '/var/lib/centreon/centplugins': Operation not permitted


 

 

Yesterday my centreon was totally off.

Almalinux won’t start , I had a “Corruption of in-memory data” and couldn’t mount the /var/lib/centreon , hopefully easily repaired with xfs_repair .

 

So for now I don’t really understand what’s happened.

I think that I will restore all my centreon.

By followhing this ticket I saw Laurent advice:

Export configuration permission error | Community (centreon.com)

Yesterday my centreon was totally off.

Almalinux won’t start , I had a “Corruption of in-memory data” and couldn’t mount the /var/lib/centreon , hopefully easily repaired with xfs_repair .

So for now I don’t really understand what’s happened.

 

Hello, 

 

not sure about the error with the corruption of data, but, about the “Operation not permitted”, here some clues:

You only can change the owner of the group if:

  • you are root
  • you and the new owner are on the same group.
  • The file system is not read-only or don’t have some immutable flag

1 - Well, your actual user is centreon-engine and you are trying to change the owner/group of a file to centreon… double check if the centreon-engine are in the centreon group

centreon-engine:~$ groups 
centreon-engine centreon centreon-broker centreon-gorgone

 

2 - Your directory/files looks like be under SElinux ACL (see the . (dot) at the end of the drwxrwxr-x. for example).  Maybe you have some ACL that are blocking the changes.. double check it with the command “ls -Z” for example and use getfattr/setfattr to change it if necesary.

 

Good luck

Hi yes , centreon-engine is in the centreon group

su centreon-engine
bash-4.4$ groups
centreon-engine centreon-gorgone centreon-broker nagios centreon
 

And you are right , I forgot to tell that activate SeLinux , it’s now on permissive mode.

I saw 2 things:

  • this

 

  • and this , so I think I found what’s wrong
