Cannot understand from output of lsblk

I cannot understand from the output of lsblk what partition is mounted in /:

[myname@fedora etc]$ lsblk -o PATH,SIZE,RO,TYPE,MOUNTPOINT

lsblk shows block devices. It can get confusing when you have something like btrfs where a single block device is mounted in multiple places. lsblk -f will show you all the mountpoints of a partition.

Alternatively, findmnt is likely a better tool for this application. For example, findmnt --real will show all your mountpoints or findmnt / will show you how / is mounted.


I will suggest that entries:


They mean you use Ubuntu Snap. Over time, these entries can arrive;)

A minor addition to what others have said:
For btrfs filesystems, the “MOUNTPOINT” column only shows the most recently mounted subvolume. Newer versions of lsblk have added a “MOUNTPOINTS” column that lists all the mounted subvolumes for each device.

Fedora’s util-linux package is currently version 2.36.2, whereas the latest upstream version is 2.37.2. Until Fedora updates util-linux, I agree with @dalto: findmnt is the best tool to see exactly what is mounted where.


@gregoryhinton thank you very much
