Hi,

I got a problem when mounting virtiofs in kernel5.1 as below:

fuse: loading out-of-tree module taints kernel.
fuse: module verification failed: signature and/or required key missing - tainting kernel
fuse init (API version 7.29)
virtio_fs virtio1: Cache len: 0x80000000 @ 0x180000000
virtio1 initialised, 524288 pages in 12ms
virtio_fs_find_instance: fs->tag myfs, tag /dev/null
virtio-fs: tag </dev/null> not found
Mounting FUSE Control File System...
[/bin/bash]: [mount -t virtio_fs /dev/null /mnt/virtiofs/ -o tag=myfs] return code=[32], execute failed by [root(uid=0)] from [pts/0 (9.4.90.78)]

And my kernel code is:
https://github.com/rhvgoyal/linux/commits/virtio-fs-dev-5.1

I wonder if the mount command has been changed?

Thanks,
Jun

There was a change that went in last night, I believe the new format is:

mount -t virtio_fs myfs /mnt/virtiofs/

with the tagname going into the device position.

Does that work?

Dave

Hi Dave,

Thanks for your quick reply, and still mount failed. But I can not get
some useful message from dmesg.

# mount -t virtio_fs myfs /mnt/virtiofs/
mount: wrong fs type, bad option, bad superblock on myfs,
missing codepage or helper program, or other error

In some cases useful info is found in syslog - try
dmesg | tail or so.

This is working for me - but with the latest -dev qemu/virtiofsd as
well; please make sure both are up to date:

I used:

mount -t virtio_fs myfs /sysroot -o rootmode=040000,user_id=0,group_id=0,dax

Hi Dave,

It works when adding "-o rootmode=040000,user_id=0,group_id=0,dax".

Thanks,
Jun

OK, great.  Hmm I wonder which option is the required one.
