Snapshot (mass) delete limit of 100 at a time

[somewhatdamaged]

TrueNAS Core gives the option to delete all snapshots, but SCALE only allows 100 at a time. Infuriating if you have thousands. Any ideas? I don't want to have to resort to the command line ideally

Making snapshots is very cheap, but deleting snapshots is quite expensive and requires metadata changes.

I assume this is a mechanism that has been added to avoid system performance issues. It should be documented or configurable... I'll check with the (very busy) engineering team.

It looks like this is a bug (perhaps in the UI)... can you report-a-bug?

zfs list -t snap | awk '/<pattern>/ { printf "zfs destroy %s\n", $1 }' | sh

Use the shell for stuff like that!

I use as example this command when I want to get rid of all snapshots called "foobar":

Code:

zfs list -H -o name -t snapshot | grep foobar | xargs -n1 zfs destroy -r

Good morning chaps, thanks for the reply. Yeah, i know that the shell is probably the best option, but i'm not super au fait with the command line stuff, and just wondered why it was so easy on Core, and limited to 100 at a time on Scale. I've managed to delete the snapshots now after some faffing

It's super important with these commands to make 200% sure you never delete any snapshot of ix-applications or it's children.
