OverlayFs can't mount

I wanted to try a bit overlayFS.
But i can't get to mount the overlayFs

sudo mount -t overlay -o lowerdir=~/box1/lower,upperdir=~/box1/upper,workdir=~/box1/workdir overlay ~/box1/merged
mount: special device overlay does not exist

Any hint?

Re: OverlayFs can't mount

As the error indicates, you need to specify a proper device file.

You can explain better? I looked around the net and the syntax looks fine.

Re: OverlayFs can't mount

Every command I read mentions the order

mount -t overlay overlay

though from what I gather your way should work as well

Also something that might get forgotten occasionally, there wasn't a kernel update from which you didn't reboot yet?

After getting stuck with this error I changed a bit the param order following other people example from the web. And i rebooted my pc during the test, just in case.

Omg fixed. Sometime you can look at the problem without seeing it. I put on mount params ~/box1/lower but my folder was ~/box1/low
Sorry

Would have been my next guess, don't forget to mark the thread as solved by appending SOLVED to the title of the thread.
