I am already using sanoid to manage zfs snapshots. Now I’m going to use syncoid to transfer those snapshots to another host. Both sanoid and syncoid are …

Moving some ZFS filesystems to the ‘trash’ and removing all their snapshots – sanoid

I recently discovered that you can delete all snapshot from a ZFS filesystem with a single command. It came to me via fortune: You can delete a range of ZFS snapshots (a-z) in multiple ways. The following will delete d and all earlier snapshots: zfs destroy mypool/data@%d To delete d and all later snapshots: zfs …

More recently, I started using a zfs snapshot for caching clearing. The purpose of this post is to document the existing configuration of the production FreshPorts …

bectl details

This is just a placeholder for me to find this later. I was cleaning up some old snapshots. I’m not sure I should have removed those snapshots and I’m saving this here for next time I use bectl.

zfstools & sanoid – snapshots on the local host

I’m going to implement zfstools on all my ZFS-based hosts today. I first started using this tool in July 2019. In this post: FreeBSD 12.0 and 12.1 zfstools 0.3.6_1 sanoid-2.0.1_2 Local snapshots only I will be using zfstool only for creating local snapshots. If I wanted snapshots for sending to other hosts, I would probably …
