I have 4 new storage devices to create 2 new zpools, each a two-vdev mirror. Let’s go. In this post: FreeBSD 14.3 These are the drives I have. As an Amazon Associate I earn from qualifying purchases. The 4TB NVMe cards are Samsung 990 EVO Plus SSD 4TB, PCIe Gen 4×4 | Gen 5×2 M.2 The 4TB SSDs are SAMSUNG 870 EVO 4TB 2.5 Inch SATA III Internal SSD (MZ-77E4T0B/AM) The new data02 […]

Now that I’ve filled up data01, I bought some more SSDs and created another zpool. Today, on this snow-is-anticipated Saturday winter morning, I’m going to move some ZFS filesystems/datasets around. Side note: I like the term dataset better than filesystem. man zfs talks about datasets, which can be a file system, a volume, a snapshot, or a bookmark. However, usually when I talk about a filesystem, it might be dataset. It’s a fine

Over the past few days, I’ve posted a lot about transferring jails from two hosts into one host. One of the steps involves using zfs send | zfs recv to send the files from one host to another. I’m using syncoide for that transfer. A new fileystem’s recordsize defaults to 128K. In my case, that is usually OK, except for some specific datasets. For example: * video * backups * distfiles (tarballs) Here

I’ve started merging these two hosts: r710-01 slocum into this one host: r740-01 The goal is to then retire those first two hosts. This post covers the initial bulk copy of all the data from two hosts into the one.
