mkdir: cannot create directory : Protocol error : Virtualbox Shared folder
I am trying to create folders and file in Virtualbox shared folder from Host to guest. But i get this error mkdir: cannot create directory : Protocol error .
Below are steps i performed to share folder
1:My host OS is Ubuntu and my guest is Ubuntu.
2:I attached a share folder to virtualBox VM
Folder Path:/DR/vault/config
Folder:config selected automount and make permanent.
3:In Guest OS i installed virtualbox guest additions
4:I am trying to mount folder on /mount/config path
I added entry in guest's /etc/fstab as
/config /mount/config vboxsf rw,uid=1000,gid=1000 0 0
Path gets successfully mounted after Guest reboot also i can see the files created in /DR/vault/config(Guest) to /mount/config(Guest) but i cant create folder or file in /mount/config (Guest)
Please suggest if anything is missing or if there is any other way.
I have found this is a problem with filename lengths on DOS hosts. I have been using VirtualBox VMs as a form of containerised environment for deploying to a JBoss server, having experienced far too many problems with Windows environments for said technology. I was using a shared-directory with my host machine as I was trying to keep the virtual machine lightweight (ie keeping IDEs in the host machine), then checking code into the shared directory for deployment with Maven. However, maven was giving some odd errors when the directory length grew to over 255 characters. Try looking at your file absolute path (type "pwd") and seeing if it's longer than 255.
I've resolved this problem with the following:
vboxsf group: sudo adduser username vboxsf My host OS is Windows, my guest OS Ubuntu.
在我的情况下，我让驱动器已满，清除驱动器上的一些空间解决了问题。
