So, I have one 9p mount working correctly, and several not working. The one that is working is a drive mounted outside the array, all my array shares are not working. This Ubuntu VM is using a the virbr0 for connectivity. I get no mount errors, yet I can only see stuff on "encode" the rest stays blank. "encode" is mounted outside the array, formatted as XFS; all my shares in the array are also XFS. I'm also only seeing speeds of ~50MB/s from a "encode" to a samba share on the server.

Sorry for necroing the post, but did you ever manage to get this working? I had problems with 9p as well, but I can mount everything, but I just can't create new files into the shared folders. But I can edit, rename and delete existing files and folders (?!). While some other mount shares (with the exact same permissions and setup) working without problems. I had better luck with mounting shares from the array itself, and not the unassigned ones. Now I suddenly struggle a bit with a cache drive, while the regular "user" share works as expected.

With one of my VM's I just ended up using NFS, at least it works, but it seems to be limited to 1Gbps which is not ideal for an nvme device. Maybe I should open a virtual network as well and not just passing it through. But 9p would been nice to use and simple in theory.. if it would work as expected.
