    Other gpart leaves free space before partition 1 - is this normal?

    I have a ZFS pool consisting of two drives in a mirror VDEV. Now I'm replacing one with a larger capacity. So I first add the 3rd (new) drive to the VDEV for resilvering, before I detach the small drive. However when I partition the new drive in the same way I partitioned my existing drives, I...
  4. Encrypting home on a system already in use

    I set up my FreeBSD-desktop nearly a year ago but with unencrypted disks (please don't ask…). Now I am in the need to encrypt at least the home directory of my user. What would be the best way to do that without reinstalling my system? I have two disks in one zpool-mirror taking up the whole...

    So I was reading one of the many articles on the spectre bug and performance decreases, and I was drawn to this article that was linked to by theregister. So this is complete malarky way of measuring this right. I know that raid controllers mess up zfs cause it can't use info from the disks...

    Hi! I have just installed the system and while looking and customizing the ZFS datasets I noticed zroot/usr is not mounted, and so /usr/* are actually in zroot/ROOT/default. Why? I mean, why the installer create that dataset by default but does not install the data in there? Is /usr...

    I have a PostgreSQL DB server running 10.3 and anytime I prune snapshots, the CPU spikes and I see database timeouts. Is there a sysctl tunable that effects the priority of snapshot deletion? I was looking at the vfs.zfs.vdev.(sync|async|scrub)_* parameters, but it isn't clear to me whether...

    ZFS Can I create a ZFS pool on bare device?

    Do I need a partition table, either GPT or MBR, on a disk if I want to boot from and use a ZFS filesystem on it? Can I just zpool create /dev/ada0 ? Then write zfsloader and zfsboot to the disk? Then boot and use it normally?
