Need to restart the multipass VM for samba shares to work properly. #3551

Open micheldiemer opened 1 week ago

micheldiemer commented 1 week ago

Description I have a shared folder in Windows. I have created a specific local user for this kind of shared. The shared folder is mounted on the multipass VM startup on /etc/fstab. The driver is Hyper-V. When booting up my computer, connecting to the VM is very slow and the folders are not shared.

To Reproduce

  1. Use Hyper-V and create a local user in windows
  2. Using windows, share a folder
  3. Install samba client on the multipass VM and mount the share in etc/fstab with the following settings : //WINDOWS-PC/multipass-bin /usr/local/smbbin cifs,vers=3.0,credentials=/root/.smbcredentials,uid=1000,gid=33,actimeo=0,closetimeo=0,iocharset=utf8,forceuid,forcegid,domain=WORKGROUP,mfsymlinks,dir_mode=02755,file_mode=0755,noperm 0 0
  4. Restart the VM. Make sure that the shared folders are working.
  5. Restart the Windows computer. Quite often, if not all the time, the shared folders are not working. multipass restart virtualmachinewithmanualsharedfolders is required.

Expected behavior I want shared folders to work all the time, having no need to restart the virtual machine for this reason.

Hey, @micheldiemer! If I understand correctly, you want to share a folder over SMB. The errors you reported are related to an SSHFS mount, which is a different technology. Are those mounts totally unrelated? Also, if you want an SMB share, Multipass on Hyper-V provides that feature through native mounts. You could do something like:

multipass mount --type native <source-dir> <instance-name>:<target-dir>
