Desperately trying to share storage from Promox host (ZFS)

[lowrisk]

I have the storage on my proxmox host using ZFS (not even sure if that a good idea? It's a M.2 SSD 2TB mostly for Plex)
-- should I use another filesystem ?

on the host I can access the file at /Storage using SSH.


I have Plex runing on one LXC and connected with "pct set 100 --mp0 /Storage,mp=/mnt/storage "
I want the same path for other VMs or Unprivileged LXC to access the same file


if I'm sharing the path to an unprivileged LXC, I'm getting read/write issue (using pct set 101 --mp0 /Storage,mp=/mnt/storage )

Then I created a SMB share from a privileged LXC to a unprivileged LXC : doesn't work (and expected I think)


a VM would be a better (safer) approach,

I added in the last ligne of etc/pve/qemu-server/102.conf

I'm a bit confuse though, because if I run that "
/usr/libexec/virtiofsd --syslog --socket-path /run/virtiofs-102.sock --shared-dir /Storage --announce-submounts --inode-file-handles=mandatory
" into SSH, nothin happen


-- also I'm not sure the QEMU Guest Agent is installed properly on the Ubuntu VM, I keep trying to install it but I still don't have copy / past
