Removing ZFS Snapshots under SCALE

TrueNAS General
1

Under CORE, I had a script that I used occasionally to clean up old “auto” Snapshots that were not a part of my “daily” set - ones created by TrueNAS itself, that I wanted to remove to free up space once I was sure I no longer needed them. That script was:

for s in `zfs list -r -t snap -H -o name /mnt/data | grep @auto` ; do
    zfs destroy -p $s ;
done

When I try to run this under SCALE (24 / Dragonfish), it doesn’t recognize the command “zfs” - is there an alternative I can use to automatically remove snapshots matching a specific text string?

Thank you!

Likely because you’re running the script as admin rather than as root. Run it with sudo and it should be fine.

That did it, thank you! I’m still getting used to SCALE after trying to follow some of the new best practices.
