It does make a difference! First only when accessing the directory on
the server itself as a non priviledged AD user. Without acl I can enter
the .snaps dir, with acl I can not.
Using Windows I wasn't able to access the privious version, but
remembering Alexanders comment I could fix that aswell!
So my share looks like this now:
[projects]
path = /srv/glvol_samba/admin/projects
comment = ARC Projekte
guest ok = no
read only = no
shadow:snapdir = /srv/glvol_samba/admin/projects/.snaps
shadow:basedir = /srv/glvol_samba/admin/projects
shadow:sort = desc
vfs objects = acl_xattr shadow_copy2 glusterfs_fuse
shadow:format = snap_GMT-%Y.%m.%d-%H.%M.%S
And my mounting unit looks like this:
[Unit]
Description=Data Dir
After=network.target
Requires=network-online.target
[Mount]
What=B741:/glvol_samba
Where=/srv/glvol_samba
Type=glusterfs
Options=defaults,_netdev,negative-timeout=10,attribute-timeout=30,fopen-keep-cache,direct-io-mode=enable
[Install]
WantedBy=multi-user.target
Now I have to test if the missing acl options has any influence on the
windows acls.
Best regards and a big big Thank you!
Regards
Sebastian
