I have problems with the main OS partition, but seems that i can't run fsck on mounted partitions?

Is there a way to diagnose mounted partition (i'm having problems lately) and if there isn't what is the best way to check it when not mounted?

You can perform a fsck on your root partition during the next reboot by creating a file named forcefsck in your root directory:

sudo touch /forcefsck
reboot

I suggest running it in "Initramfs".

dracut is a low-level tool for generating an "initramfs" images with a lot of capabilities.

Let's install it:

sudo apt install dracut

After installation is finished a new "initramfs" will be generated and GRUB will be updated automatically; It also removes initramfs-tools.

Now reboot the system, hold the Shift to make the GRUB appear (if it won't by itself), press e to edit the default menu. There is a line which starts with linux at the end of that line add rd.break=pre-mount then press Ctrl+x to continue boot process.

it means that drop me into initramfs before mounting the filesystem, Now we are in a sh shell and we can simply run fsck:

$ fsch /dev/sda1
/dev/sda1: clean,  xxx/xxx files,  yyy/yyy blocks

dracut
dracut.cmdline
