Freenas 8.3.1 howto cleanup replicated snapshots

Hi,
how can i clean up replicated snaphots?
they are not removed after there lifetime, and the storage is full.
So replication fails for new snapshots.

Hi,

If you configure your replication task with the Recursively replicate option it will also automatically destroy all snapshots on the destination that do not exist on the source. This works even if you replicate one dataset and there is nothing to do recursively.

If you want to destroy the snapshots manually you can use the ZFS Snapshots view in the GUI (http://doc.freenas.org/index.php/Periodic_Snapshot_Tasks) -- it allows you to view / filter & destroy the snapshots.
If you want to use the CLI you can run:
[panel]zfs destroy %snapname[/panel]It will destroy all snapshots older than and including snapname. The automatic snapshots are named <dataset_name>@auto-<date>-<expiration>. You can run "zfs list -t snapshot" to get list of all snapshots.

thx that helped.

i wanted to have more snapshots on the replicated system as on the productive.

i had to enter zfs destroy <dataset_name>@%auto-<date>-<expiration> to delete the old snapshots.


thx a lot this saved my day
