Bitbake server does not start

Question

I am having some trouble with building the Yocto project, hope I can find some help. Is there any way to fix the following issue? Let me know if you need any more information. Thanks.

My goal

I am building the default image from this guide : https://docs.yoctoproject.org/brief-yoctoprojectqs/index.html This build takes up a lot of space, so I want to build it on a network drive.

Current situation

I am able to finish the build normally if I am using a normal folder. If I use the the shared drive that is mounted in the system, the build never starts. The error looks like this :

$ bitbake core-image-sato
NOTE: Bitbake server didn't start within 5 seconds, waiting for 90

Details

The /etc/fstab line to mount the drive is :

NetworkShare /mnt/NetworkShare 9p trans=virtio,version=9p2000.L,_netdev,rw 0 0

The host is Ubuntu server 20.04 running in a VM inside UnRAID. I don't think the VM is the issue (It's possible that I am very wrong) because I get the same error if I mount an external share on my own computer (OpenSuse Tumbleweed) and try to build in it.

It means your hard disk is full. You should delete some files before re-running job to create a new image.
