zabbix Cannot obtain filesystem information: [13] Permission denied

[CRSTLLV]

Hello. My zabbix server does not show used space for mounted drives, that are connected on the same machine as zabbix server runs. I understand the problem, but can't find the solution. I've tried these two options, but non of them helped:

sudo chmod -R 775 drive_mounting_point
sudo chown -R user:user drive_mounting_point

Any other suggestion on how to solve this out? Thank you.

For the record, looks like you are using the vfs.fs.size key, which is the key of type Zabbix agent, which has nothing to do with Zabbix server. Anyways, it looks like SELinux issue. If you have it enabled, do you see a hint in /var/log/audit/audit.log?

[CRSTLLV]

Correct. There is zabbix agent running.

In my linux (ubuntu), i can't see the folder "audit" in this location /var/log/ :|

AppArmor? Check the options how that filesystem is mounted, is there something suspicious?

mount | grep <mountpoint>

Doing

sudo chmod -R 775 drive_mounting_point

is not always the best option because by issuing that command you enable execute bit on all the files under that directory. You don't want an execute bit on a non-executable files.

mount | grep <mountpoint>

mount | grep 10

/var/lib/snapd/snaps/snapd_16010.snap on /snap/snapd/16010 type squashfs (ro,nodev,relatime,errors=continue,x-gdu.hide)

tmpfs on /run/user/1000 type tmpfs (rw,nosuid,nodev,relatime,size=805268k,nr_inodes=2 01317,mode=700,uid=1000,gid=1000,inode64)

/dev/sdd1 on /home/user/10 type ext4 (rw,relatime)


To be honest, i have no idea what is suspicious here

Thank you for the point. How do you suggest to change it, to make it correct? p.s. under that folder there is only data, there should be no executable files.

Where exactly does that "Permission denied" error come from?

Zabbix -> Monitoring -> Latest data

Can you do a

mount | grep /home/no

?

[CRSTLLV]

That was a different one, different pattern.
