samba - Sep 2019 - vfs_shadow_copy2 not working

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 = ^autosnap_
shadow:format =
%Y-%m-%d_%H:%M:%S_\(frequently\)\{0,1\}\(hourly\)\{0,1\}\(daily\)\{0,1\}\(monthly\)\{0,1\}
#shadow:delimiter = _
shadow:sort = desc
shadow:localtime = no

I've also tried it with the delimiter line uncommented (and then removing
the underscore from the snapprefix), I've tried putting the shadow:format
syntax between quotation marks ("") as well, but it doesn't just
show up in Windows.

I think that syntax should just work according to the manual. Why is it not
working?

What does log level 10 say ?

Hi Jeremy,

Here's the log with log level 10: https://pastebin.com/0EAuz2B8

The location of the shared folder: /pool/shadowtest
The location of the snapshots: /pool/shadowtest/.zfs/snapshot
Here are how snapshots are named:

autosnap_2019-09-01_13:29:01_daily
autosnap_2019-09-01_13:29:01_hourly
autosnap_2019-09-01_13:44:09_frequently


And this is currently in my smb.conf file:


[shadowtest]
path = /pool/shadowtest
valid users = user1
read only = no
writeable = yes
guest ok = no
create mode = 770
directory mode = 770
vfs objects = shadow_copy2
shadow:snapdir = /skyhawk2x4tb/shadowtest/.zfs/snapshot
shadow:snapprefix = ^autosnap_
shadow:format =
%Y-%m-%d_%H:%M:%S_\(frequently\)\{0,1\}\(hourly\)\{0,1\}\(daily\)\{0,1\}\(monthly\)\{0,1\}
shadow:delimiter = _
shadow:sort = desc
shadow:localtime = no



I do not see the snapshots listed in the Windows Previous Version tab, so it
doesn't work, but I can't  figure out why. Any ideas?
