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?

The snapshots are being stored at /test/.zfs/snapshot

The last email had 1 little error in the smb.conf that I forgot to edit for the email: skyhawk2x4tb was the old poolname, I have it renamed to /pool now, so this is not a source of the problem. ???????

FreeBSD 12 bumps this limit to 1024. This means that you should be wary of automatic snapshot schemes that bump up toward this limit. Otherwise, the snapshots will not appear in shadow_copy2. One way to quickly tell if you're hitting the limit is to "cd" into the snapdir and "ls -l". If you've hit it then it will fail with ENAMETOOLONG.
