Unable to verify my root partition is mounted

[bonkers]

Partition table is as follows: SDA1 - root SDA2 - home -SDA5 - SWAP

Here is the output I get

rafal@rafal-desktop:~$ grep --color /dev/sda /proc/mounts
/dev/sda2 /home ext4 rw,noatime,data=ordered 0 0
rafal@rafal-desktop:~$ grep --color /dev/sda1 /proc/mounts
rafal@rafal-desktop:~$ grep --color /dev/sda1 /proc/mounts
root@rafal-desktop:/home/rafal# grep --color /dev/sda1 /proc/mounts
root@rafal-desktop:/home/rafal# grep --color /dev/sda1 /proc/mounts

What can I do? Also here is a picture of /proc in dolphin, as soon as I hover or an item it turns to 0bytes, for a glimpse just a glimpse I can see it had x amount of folders or x amount of files. This is the first time I have seen such behavior, it is as if someone does not want me to view these files and what is with the 122 TiB on the bottom, I have NOWHERE near that much space, its just a desktop.

I am not sure if I should start to be worried.

Your root partition is mounted (the system wouldn't be running if it wasn't).

1. Your root partition is likely mounted with it's UUID rather than device name so you won't find it by grepping /proc/mounts for "/dev/sda". However, you should find it if you read the whole thing, or grep for "/dev/disk/by-uuid". You can also just run "mount" to review mounted filesystems.

2. /proc is not regular directory (http://en.wikipedia.org/wiki/Procfs)

rafal@rafal-desktop:~$ grep --color /dev/sda /proc/mounts

In all flavors of Ubuntu, grep is already aliased to grep --color=auto. Check for yourself: run the alias command and observe the output.

Run cat /proc/mounts and observe the entire output. You'll see where / is mounted. Here's mine, as an example:
