            Bug ID: 1727062
           Summary: Attribute error when copying to share using
                    vfs_glusterfs
           Product: GlusterFS
           Version: 6
          Hardware: x86_64
                OS: Linux
            Status: NEW
         Component: gluster-smb
          Severity: high
          Assignee: bugs at gluster.org
          Reporter: ryan at magenta.tv
                CC: bugs at gluster.org
  Target Milestone: ---
    Classification: Community



Description of problem:


Version-Release number of selected component (if applicable):
Test system 01 {
   Fedora 30
   Gluster 6.3
   Samba 4.10.5-1
}

Test system 02 {
   Gluster 4.1
   Samba 4.9.10
}

How reproducible:
Everytime

Control test:
1. Connect to known good share which doesn't use gluster VFS module
2. With an application like pathfinder, copy some files to the share
3. Files copy as expected

Steps to Reproduce:
1. Connect to share
2. With an application like pathfinder, copy some files to the share
3. 'Attributes error' shown, 0 byte files created on share

Actual results:
'Attributes error' shown, 0 byte files created on share

Expected results:
File's copy as expected


Additional info:
Tested with both a Gluster share and a standard XFS share. This was repeated on
test system 01 and test system 02 (see above for versions). Test results:

Test 01 = Copy files with pathfinder to Gluster VFS share = Fail
Test 02 = Copy files with pathfinder to normal XFS share = Pass
Test 03 = Copy files with Finder to Gluster VFS share = Pass
Test 04 = Copy files with Finder to normal XFS share = Pass

I've collected trace gluster client logs, and debug 10 samba logs.
