I'm trying to rationalise space by moving my /var directory from its own partition to /, as currently there's a lot of wastage. I've copied /var to /newvar with rsync, and now want to mount /newvar as /var on reboot by creating an entry in /etc/fstab. This is it (using /var-tst for testing): /newvar /var-tst ext4 loop 0 0
That isn't what loop is for. loop is for associating a file with a device.
What you want is "bind", not "loop", because you're binding an _existing_ mount to another location.
but I'm getting: mount: /var-tst: failed to setup loop device for /newvar.
Because /var-tst is a directory, not a file-shaped-like-a-partition. Example from our home server: /app8tb/media/video /exports/video none bind,relatime 0 0
PS Suggestions on how to move /var without all this jiggery-pokery are also welcome.
If you want /var to be on /, rsync it as you have done, and just make a symlink as /var.
Really, all you need to do is to remove the /var fstab entry, umount the existing /var mount, rsync /newvar BACK INTO the stub /var mountpoint which is there, scrub /newvar.
No fstab trickery required (other than erasing/commenting the /var line).
Then afterwards you need to decide what to do with the partition you have been using for /var.
