In order to check the filesystem of the partition and where that partition maps to that address use:

mount -l

It will show for example that you have a partition that mounted by NFS or that a partition is ext4 and so on:

/dev/mapper/vg-var on /var type ext4 (rw,relatime,stripe=384,data=ordered)

#linux #mount #ext4 #nfs #filesystem #partition
