Something is trying to destroy a dataset

[Andiroo2]

I have some interesting lines in my log every day at noon:

 

Sep 28 12:00:01 Tower shfs: /usr/sbin/zfs unmount 'cache/CommunityApplicationsAppdataBackup'
Sep 28 12:00:01 Tower shfs: /usr/sbin/zfs destroy 'cache/CommunityApplicationsAppdataBackup'
Sep 28 12:00:01 Tower root: cannot destroy 'cache/CommunityApplicationsAppdataBackup': dataset is busy
Sep 28 12:00:01 Tower shfs: retval: 1 attempting 'destroy'
Sep 28 12:00:01 Tower shfs: /usr/sbin/zfs mount 'cache/CommunityApplicationsAppdataBackup'

 

This folder is the first dataset/folder alphabetically in my cache pool, which is a RaidZ1 setup.  This dataset is not part of an auto-snapshot or auto-backup (I recently set up automated snapshots for my appdata and domains datasets via the SpaceinvaderOne tutorial). Here's the view from ZFS Master:

 

 

The destroy is failing (thankfully?) but I'd like to know what's trying to kill it.

The mover? How is that share configures for primary, secondary and mover action?

[Andiroo2]

Aha, I run mover on this share a couple times per week.  Would this "destroy" the dataset once it empties it out?

Yep.
