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 Dave > On 2019/7/23 16:31, Dr. David Alan Gilbert wrote: > > * piaojun (piaojun@huawei.com) wrote: > >> 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? > > > > 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 > > > > > >> Thanks, > >> Jun > >> > >> _______________________________________________ > >> Virtio-fs mailing list > >> Virtio-fs@redhat.com > >> https://www.redhat.com/mailman/listinfo/virtio-fs > > -- > > Dr. David Alan Gilbert / dgilbert@redhat.com / Manchester, UK > > . > > -- Dr. David Alan Gilbert / dgilbert@redhat.com / Manchester, UK ^ permalink raw reply [flat|nested] 6+ messages in thread
