Hey guys, i opened a new thread because the subject was different.
So, this started because my ubuntu 20.04.2 had the disk full. i was trying to delete files but all i had was permission denied.

After, i unplugged this ssd disk from the ubuntu server and attached it to a laptop with ubuntu.
at first i wasnt seeing the partition, however after doing "$ sudo apt-get install lvm2" the partition popped up and i can see the folders.

But i cant delete folders or see everything on the disk. I wanted to know where is all the disk space occupied.
How can i do this?

Thanks!!
