How do I check the filesystem type of a device?

I formatted a partition using mkfs.xfs /dev/mydevice in Ubuntu and then I mounted it using /etc/fstab. When I type mount, it tells me that my device is mounted as ext3.

Output of mount:

/dev/mydevice on /mnt/mymount type ext3 (rw,_netdev)

First question: How do I know if it's xfs or ext3? What am I missing?

Second question: If it's xfs, how do I know if it's xfs-256 or xfs-512?

Solution

  • loading the device in a utility like gparted tells you FS types. for fstab file it's enough, I think, to say only xfs.
