[Gluster-users] URGENT: Update issues from 3.6.6 to 3.10.2 Accessing files via samba come up with permission denied

[Diego Remolina]

Hi,

Over the weekend we updated a two server glusterfs 3.6.6 install to
3.10.2 We also updated samba and samba-vfs to the latest in CentOS. I
enabled several of the newer caching features from gluster 3.9 for
small file performance and samba, and we now seem to have some issues
with accessing files from glusterfs. When users try to access some
files, they get a Permission denied message. This seems to be only via
samba as I am able to su - username and then do strings on the file.

[root at ysmha02 gluster-backups]# rpm -qa | grep gluster

On the samba logs for the machine I notice something weird, samba
seems to be trying to stat the file we are trying as a directory to
see if it contains desktop.ini:

[2017/05/30 10:13:07.297026,  0]
../source3/modules/vfs_glusterfs.c:870(vfs_gluster_stat)
 glfs_stat(ACTIVE/Automotive/FORD/AN - Ford East/02
DRAWINGS/CURRENT/AN-FORD EAST_04-05-17_CD_R17.rvt/desktop.ini) failed:
Not a directory
[2017/05/30 10:13:07.298155,  0]
../source3/modules/vfs_glusterfs.c:870(vfs_gluster_stat)
 glfs_stat(ACTIVE/Automotive/FORD/AN - Ford East/02
DRAWINGS/CURRENT/AN-FORD EAST_04-05-17_CD_R17.rvt/desktop.ini) failed:
Not a directory

This seems to be happening only with files with the .rvt extension.
Though these files are usually larger in size vs other smaller excel,
power point, etc files.

Here are the complete options for the volume:

I turned off performance.cache-samba-metadata again to see if that
would help, but seems it does not help.

I really appreciate any help with this.
