Hello
here is my "df -h" output
kmaster:~$ df -h
Filesystem Size Used Avail Use% Mounted on
udev 2.0T 0 2.0T 0% /dev
tmpfs 404G 618M 403G 1% /run
/dev/sda1 94G 9.9G 80G 12% /
tmpfs 2.0T 0 2.0T 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 2.0T 0 2.0T 0% /sys/fs/cgroup
tmpfs 404G 0 404G 0% /run/user/1000

this server has only 100GB storage, but in esxi it shows 4TB
i have kubernetes master node on this server

Any Suggestion

The only disk storage I see is 80G sda1. Everything else is virtual. What problem do you have?

I wanted to know why linux assigning 2T to /dev
udev 2.0T 0 2.0T 0% /dev

in vcenter server you see this server is using 4TB, so it's difficult to analyse the report , i dont know how to explain that

Thanks

no, 2T is not assigned. That is only the theoretical maximum. You can safely ignore tmpfs and udev.

It simply means that a 100GB partition was set up on disk sda. Run lsblk to see disk sizes.

How was this server installed, and what distro is that?

Its a debian 9 and is running kubernetes master node

Thanks all
