Version of s3fs being used (s3fs --version)

V1.91

Version of fuse being used (pkg-config --modversion fuse, rpm -qi fuse, dpkg -s fuse)

Kernel information (uname -r)

Details about issue

All things work well with s3fs only. But if I export the mount point via nfs, I cannot cp/mv a file from local drive to nfs mount point.

How to reproduce

On NFS server

Create a s3fs mount point on NFS server, /mnt/test
Add /mnt/test into /etc/exports, /mnt/test/backup/tests 10.*.*.*(rw,sync,fsid=11,anonuid=0,anongid=0)
Start nfs server, systemctl start nfs

On NFS client

Create a folder, mkdir /mnt/s3fstest
Mount NFS, mount -t nfs [nfs-server-hostname]:/mnt/test /mnt/s3fstest/
Test

a. Copy a file from local drive to s3fs moun point

touch /tmp/e
cp /tmp/e /mnt/s3fstest/e
cp: cannot create regular file '/mnt/s3fstest/e': No such file or directory

b. Touch a new file

# touch /mnt/s3fstest/e
touch: setting times of '/mnt/s3fstest/e': No such file or directory

c. Move a new file

# mv tmp/e /mnt/s3fstest/e
mv: cannot create regular file '/mnt/s3fstest/e': No such file or directory

d. Create a file thru >

It works

# ls /mnt/s3fstest/e
ls: cannot access '/mnt/s3fstest/e': No such file or directory
# date > /mnt/s3fstest/e
# ls -l /mnt/s3fstest/e
-rw-r----- 1 root root 32 Aug 15 18:29 /mnt/s3fstest/e

e. Create a file thru vim

It works

# ls /mnt/s3fstest/f
ls: cannot access '/mnt/s3fstest/f': No such file or directory
# vim > /mnt/s3fstest/f
# ls -l /mnt/s3fstest/f
-rw-r----- 1 root root 32 Aug 15 18:29 /mnt/s3fstest/f

Summary

Permission is correct because I can create a file thru > and vim.

But it's weird that cp, mv, touch don't work with NFS. And the NFS version would fallback to v3.

Could you give me some suggestions?

@zhan9san
Added update_parent_dir_stat option to update parent directory stat information when file operations are performed.
With this, I think that you can catch file and directory updates when used with NFS.
See #2016 for details.
Try using master's code with the update_parent_dir_stat option.

This issue will be closed, but if you still have problems please reopen it or post a new issue.
