error - trying to mount a directory between two containers

[HenryTheTech]

im sure this is a stupid question, but...

I keep getting this error:

command 'mkfs.ext4 -O mmp -E 'root_owner=0:0' /zvol/henry/tmp/images/123/vm-123-disk-1.raw' failed: exit code 144 (500)

and all I am trying to do is add this directory to a couple of containers to transfer some data.

It is technically not possible to mount an ext4 formatted disk on multiple containers (ext4 is not a shared file system).

But I cannot mount the directory even in a single container? What sort of filesystem does the mount dir function require?

Its not clear on this page:

Why do you use a directory storage when you have ZFS? Please use a ZFS storage instead ...

 

[HenryTheTech]

Because I am trying the simplest method to simply pass data from one conatiner to the next. Using the ZFS mounts isn't working because each container is just creating separate subvols when I mount the same ZFS storage. I can find many posts online with people experiencing similar issues, but can't find a resource outlining the procedure.

You can simply mount a directory from the host (instead of using storage volumes).

I see. Thanks
