snapshots contain no data.

[James B. Byrne]

I implemented snapshots on my desktop unit.  the zfs pool looks like
this:

zfs list
NAME                 USED  AVAIL  REFER  MOUNTPOINT
zroot               40.4G   851G    96K  /zroot
zroot/ROOT          13.1G   851G    96K  none
zroot/ROOT/default  13.1G   851G  9.14G  /
zroot/tmp           76.4M   851G  2.56M  /tmp
zroot/usr           26.9G   851G    96K  /usr
zroot/usr/home      26.3G   851G  22.4G  /usr/home
zroot/usr/ports      638M   851G   638M  /usr/ports
zroot/usr/src         96K   851G    96K  /usr/src
zroot/var            131M   851G    96K  /var
zroot/var/audit       96K   851G    96K  /var/audit
zroot/var/crash       96K   851G    96K  /var/crash
zroot/var/log        118M   851G  2.60M  /var/log
zroot/var/mail      1.29M   851G   120K  /var/mail
zroot/var/tmp       11.3M   851G  5.45M  /var/tmp

This is one of the snapshot commands I am issuing from cron:

/usr/local/sbin/zfsnap snapshot -a 14d -s -S -r zroot



But when I look in the snapshot directories I see no data.

This is the result:

ls -a /zroot/.zfs/snapshot/*14d
/zroot/.zfs/snapshot/2017-10-10_11.10.00--14d:
.	..

/zroot/.zfs/snapshot/2017-10-10_12.10.00--14d:
.	..
 . . .

/zroot/.zfs/snapshot/2017-10-23_14.10.00--14d:
.	..


This is busy system and I have made many changes to the file system
since starting this on October 10.  Why are there no snapshot
references to changed files or where do I find them?
