System volume root's usage is 88%. This condition should not occur under normal conditions.
Hello!
I have checked the other threads.
My firmware version is 6.10.6, I don't have clamav .tmp files but i see too much logs.
How Can I delete it safely?
So, Shall I do it?
What happens if the root partition reaches 100%?

As it fills, you can end up with damaged configuration files, since the NAS can't write anything to the partition. Sometimes that results in a NAS that can't be booted.

You must have installed rsyslog at at some point (as an app). Does it show up in the installed apps section?
How exactly did you mount on /mnt? Did you enter
# mount --bind / /mnt
If that is what you did, then /mnt/data should be an empty folder. So you can delete everything in the folder, but don't delete /mnt/data itself.
I've mounted the OS on /mnt on my own system (an RN526). You can compare what you see when you enter du -csh /mnt/* on yours:
root@NAS:~# du -csh /mnt/* 0 /mnt/apps 6.4M /mnt/bin 0 /mnt/boot 0 /mnt/data 24K /mnt/dev 11M /mnt/etc 30M /mnt/frontview 0 /mnt/ftp_ban.tbl 0 /mnt/home 4.0K /mnt/homes 33M /mnt/lib 4.0K /mnt/lib64 0 /mnt/media 0 /mnt/mnt 4.6M /mnt/opt 0 /mnt/proc 36K /mnt/root 0 /mnt/run 11M /mnt/sbin 0 /mnt/srv 0 /mnt/sys 0 /mnt/tmp 297M /mnt/usr 681M /mnt/var 1.1G total
It won't be exactly the same, but it will help sort out what else needs to be deleted.

No, It doesn't.
I have no installed apps.

Yes, I did.

Shall I just delete it?

Not now perhaps. But there clearly was stuff installed (either as an app or via ssh) before. Rsyslog didn't get there on its own. There are also signs of mysql and php5. Maybe some other stuff too.
Do you recall what was on there in the past?

As I tried to say before: Don't delete /mnt/data. It is a mount point, so it needs to exist in the system. Do delete /mnt/data/rsyslog

Here's the other large folder that doesn't normally exist on a ReadyNAS. Not sure if this was part of php5 (which appears to have installed at some point), or something else.
You could just delete the /mnt/var/lib/mysql folder. You could also copy it to a share on the data volume (/data/... - not /mnt/data) first.
Deleting both of these folders should bring the free space in OS partition up to where it should be.
