SSHFS for Remote Filesystems
Mounting a filesystem locally via SSH is not rocket science with sshfs. You don't even need root privileges because it is a Filesystem in Userspace. As shown in Listing 3, a call to sshfs is sufficient to mount the /home/tktest directory locally on server 192.168.56.105. You can work with the target directory as with any other normal directory, even though it is on the remote server.
Listing 3
Mount /home/tktest Directory
$ sshfs tktest@192.168.56.105:/home/tktest ./sshdir/ tktest@192.168.56.105's password: $ cat /proc/mounts | grep ssh tktest@192.168.56.105:/home/tktest /home/user/tmp/sshdir fuse.sshfs rw,nosuid,nodev,relatime,user_id=1000,group_id=1000 0 0
Conclusion
As an alternative to the simple block devices featured so far, you can create stackable block devices that offer additional features, such as the Logical Volume Manager (LVM) already discussed, software RAID (MD/RAID), a distributed replicated block device (DRBD), or device mapper targets.

Read-only file compression with SquashFS
If you are an intensive, or even a typical, computer user, you store an amazing amount of data on your personal computers, servers, and HPC systems that you rarely touch. SquashFS is an underestimated filesystem that can address that needed, but little used, data. -
