I recently tried to cleanup partitions on my hard drive and to learn about their use for my windows and linux operating systems. However I am puzzled with a specific partition on my hard drive and whether it can be deleted.
Gparted shows the partition in question as an unmounted ext4 partition with 0 (?) available space.
I tried to investigate further using parted and df.
sudo parted -s /dev/nvme0n1p2 print
gave the following output:
Model: NVMe Device (nvme)
Disk /dev/nvme0n1p2: 5243MB
Sector size (logical/physical): 512B/512B
Partition Table: loop
Disk Flags:
Number Start End Size File system Flags
1 0,00B 5243MB 5243MB ext4
This seems to indicate that the partition is empty (?) since it is not mounted, there are no flags and the partition table is set to loop, which I understood to be some sort of default.
The output of df /dev/nvme0n1p2 kept me puzzled.
Filesystem 1K-blocks Used Available Use% Mounted on
udev 8080832 0 8080832 0% /dev
I read in a different thread, that udev is actually a virtual filesystem and the 0% use is normal due to it living in RAM. I do not understand however why it is listed in this specific partition and not in any other place. Further df -h does not list the partition or any other udev partition at all.
I dont understand the (nonexistent) use of this partition or how and by whom it was created in the first place. Could it be related to some other System, such as the Grub-Bootloader (I run Windows and Ubuntu) or some other unknown system? Why does df show this as the location for udev?
Thanks in advance for the help.
