Remove all ZFS snapshots

7th July 2008, 11:08 am

Here’s a small bash script to destroy all existing zfs snapshots.

Run at your own risk!  :-)

#!/bin/bash
for snapshot in `zfs list -H -t snapshot | cut -f 1`
do
zfs destroy $snapshot
done

    Hi,
    It’s better to get rid of cut command:
    for snapshot in `zfs list -H -o name -t snapshot`
    (…)

    :)

    Well,

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

    is even better :-)

    I found that when deleting snapshots from multiple shares this works okay:

    zfs list -H -o name -t snapshot|grep nameofzfsshare|pfexec xargs -n1 zfs destroy

    while trying the same thing we came up with this line
    It helps to see what is going to be deleted

    zfs list -H -o name -t snapshot | grep | while read SNAPSHOT;do echo $SNAPSHOT; zfs destroy $SNAPSHOT;done
