I do not understand none file system.

which is none filesystem?

I have something wrong?

  • using the -T flag shows the type of fs too, the "none" ones are all tmpfs as Rinzwind knows. As to why the Filesystem column is a mix of type, or device, or none or sometimes tmpfs...? – Xen2050 Dec 14 '14 at 15:57

"none" means it is a temporarily mounted filesystem storage (created by the kernel). The storage does not happen on your hard disk drive but happens in memory (or in the swap space).

Nothing is wrong. I have the same.

/dev/sdb2       219G   19G  190G   9% /
none            4,0K     0  4,0K   0% /sys/fs/cgroup
udev            7,8G  8,0K  7,8G   1% /dev
tmpfs           1,6G  1,4M  1,6G   1% /run
