Hi all, At some point recently my customers can no longer see GPFS snapshots under the Windows Previous Versions tab. It simply says "No previous versions available". If a fileset is exported with the flag "force user = root" then Previous Versions *are* displayed. [2016/07/06 10:07:35.602080, 3] ../source3/smbd/vfs.c:1322(check_reduced_name) check_reduced_name:

Greetings, I am trying to use vfs_shadow_copy2 with samba samba-4.2.7. I have a share exported at /export/smb400/.

Samba configuration for the share is: vfs objects = shadow_copy2 shadow:snapdir = /export_shadows/volume-00000001 shadow:fixinodes = yes (Note: I

Hi all, Does anyone have vfs_shadow_copy2 working with an alternate snapshot directory format?

Hello Dear Samba Users, I have sucessfully set a samba share on a centos 7 box (samba 4.6.2) and succeeded into make work snapshots (vfs_shadow_copy2 with xfs and lvm). The snapshots appears well in windows previous versions. However, I expected to go further with snapshots and use the options "shadow:snapprefix" and "shadow:delimiter"in order to filter daily, weekly

Hi Sebastian, why are you using shadow:snapprefix if this is just ?snap?? Does it work using ONLY shadow:format = snap_GMT-%Y.%m.%d-%H.%M.%S ? If you use snapprefix you also need to use shadow:delimiter (in your case this would be ?_?). However, I never managed to get it working with snapprefix on my machines.

Hello all, I already successfully configured shadow copy service without a delimiter and regex. But as soon as I try to get this to work with regex, nothing shows up on the win client. My config looks like this: [global] shadow: localtime = yes shadow: sort = desc shadow: format = _%FT%T shadow: delimiter = _ shadow: snapprefix = ^\(monthly\)\{0,1\}\(weekly\)\{0,1\}\(daily\)\{0,1\}$

Hi, I thought I should share this unusual behaiviour of samba 4.1.11. All of a sudden while I tried to delete a Folder via samba on a share it crashed. I was using Mac OSx's V 10.9.4 internal samba client (regular "CMD+K" mount via Finder). Server: [...] FreeBSD 10.0-RELEASE-p7 #0: Tue Jul 8 06:37:44 UTC 2014 root at amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC

So I'm trying to get shadow copies to work with Windows clients. The snapshots are being stored at /test/.zfs/snapshot The snapshots are being named like so: autosnap_2019-08-10_21:00:00_frequently autosnap_2019-08-10_21:00:00_monthly autosnap_2019-08-10_22:00:00_hourly This is in my smb.conf: [test] vfs objects = shadow_copy2 shadow:snapdir = /test/.zfs/snapshot shadow:snapprefix =

Hmm looks like earlier return for users with root permission, so admin users would not go through SMB_VFS_GET_NT_ACL(), which takes more time on permission checking.[1] Non-admin users would go
