This answer states:A mounted network share will have a deviceId which is why you can  create a symlink to a mounted location.So, if a mounted network share will have a deviceId, files mounted with sshfs will have a physical device associated with them, like any other filesystem would do. I mounted a remote directory in the local system (Ubuntu 14.04) withsshfs user@remotehost:/remote/directory /home/local/directoryIn the output of mount of the local system a corresponding line is correctly displayed:user@remotehost:/remote/directory on /home/local/directory type fuse.sshfs (rw,nosuid,nodev,relatime,user_id=1000,group_id=1000)For all the files in /home/local/directory/, stat outputs Device: 30h/48d. But neither in /sys/dev/block, nor in /sys/dev/char there is such a local device with major number 3!So, what kind of device is it where can I find it in my local system?
Device major/minor number for remote filesystem
files;filesystems;mount;devices;sshfs
Sshfs uses FUSE, the File System in UserSpace infrastructure, so it's not associated to a block device at all (and of course not to a character device, either). I don't know how the device number stats output is related to that kernel infrastructure, if it is related at all and not just random content.
