Linux – fstab not mounting a disk on boot

Key-based authentication can only work if the ssh process can find your key. You presumably have your key in your home directory; but you've never told sshfs where to look for a key. At boot time, it would be root mounting all filesystems, therefore the key must be either in /root/.ssh or referenced in /root/.ssh/config.

I recommend mounting the filesystem after you've logged in, and as your own user. Put this in a script that's executed when you log in:

ssh-add ~/.ssh/name_of_key.id_rsa
sshfs homeserver:/media/usb0 ~/exthd

Put an alias called homeserver in your ~/.ssh/config:

Host homeserver
HostName 192.168.0.2
User oli

You can use \x20 for space.

That is hex value for ASCII (and utf-8 encoded) space.

Or you can use the octal variant \040.

So that would be (in fstab):

UUID=01CD72098BB21B70 /media/tusharmakkar08/Local\x20Disk1
# or
UUID=01CD72098BB21B70 /media/tusharmakkar08/Local\040Disk1

If you are not to familiar with ASCII fun install ascii and:

ascii     # decimal and hex view
ascii -o  # octal view

Non the less I'd also recommend, like @TNW, changing the mount point to one without space. Generally makes things easier. You can also change the label though that might affect other things if you have something configured to recognize it as it is.
