[Gluster-users] Owner of some directories become root

[Shozo Ozawa]

Hi Friends.



I have some problem on glusterfs 3.3.0.



Description of problem:

When writing directories to a replicate volume, some directory owners become
root.



Version-Release number of selected component (if applicable):

glusterfs-fuse-3.3.0-1.el6.x86_64

glusterfs-debuginfo-3.3.0-1.el6.x86_64

glusterfs-server-3.3.0-1.el6.x86_64

glusterfs-3.3.0-1.el6.x86_64



How reproducible:





Steps to Reproduce:

1. install the above gluster release

2. setup a new 3 replicated volume

3. write directory via NFS, user is "users"



Actual results:

Owners of some directories become "root".



[root at test01 volume]# ls -l 01/000/000/000/256

Looking　all the server logs (/var/log/glusterfs/bricks/mnt-volume.log),
reveals "failed to set gfid" on target directory at the correct time:

Expected results:

Owners of all directories become "users".



Additional info:

Checking sar, disk I/O is high at the correct time compared with normal
time.
