mount: make rename fall back to copy then delete (was unable to move files in mounted hubic)

[thammi]

I mounted a hubic remote target and tried to move a file:

$ mv blub bla
mv: cannot move 'blub' to 'bla': Input/output error

My rclone command (rclone mount -vv hubic_open:default ~/mnt/) displayed the following error:

I am using rclone v1.37 on Debian 9.2 amd64. This limitation is not mentioned in the online documentation. Renaming inside mounts works using Dropbox.

Having this feature on hubic would be very useful to me. I am actually trying to rename inside an encrypted storage based on the hubic target, so renaming using the webinterface is very hard.

openstack swift and hence hubic doesn't actually have a server side move.

It does have a server side copy though. If you use rclone move to move things it will do a server side copy followed by a delete.

It looks like I thought of implementing this in rclone mount but didn't yet.

I'll re-purpose this ticket to implement that.

In the mean time you can use rclone move to do it which isn't quite as convenient - sorry!

I tried using rclone move but ran into #515.

That is unfortunate :-( I'd love to get some help with that or this issue if you've got the time!

I hope this someday. I'm using the Rstudio server on the mounted Swift device, but Rstudio cannot save the working image, that works with the rename.
