    ZFS Can disks in a pool be replaced with smaller drives?

    I currently have a system with 12x 5TB 2.5" HDDs. Due to a batch of cheap/faulty SATA cables, one of these drives failed hard (and was replaced), and a couple of the drives are now showing bad sectors. I've replaced the cables and the system is a lot more stable, but since I'll inevitably have...

    ZFS zfs and realtime mirroring

    I'm curious if there's any kind of realtime (or lagging realtime) remote mirroring option for ZFS. I have plenty of mirroring going on locally, but I'd also like to mirror across the network to another server. I know enough about SEND and RECEIVE to know I can send snapshots, but what about in...

    ZFS Nextcloud, ZFS and Redis

    Let there be a FreeBSD host running ZFS with Nextcloud (a PHP application). The Nextcloud documentation states: It then proceeds by suggesting using Redis as a data cache. For this discussion, let's ignore the PHP opcode cache and solely focus on the "data cache" (i.e. files hosted by...

    Mirrored vdevs or RAIDZX

    I’ve got 4 1tb 5400rpm drives and 3 256gb ssds- all sata. I can install any 4, maybe 5. I was reading up on zfs raid levels and it’s a little confusing. Do I install FreeBSD on one of the ssds and then create a set of mirrored vdevs out of the four hdds, or a single mirror out of the other 2...

    Solved Unable to delete BE

    So, I just wanted to fix up my "playground" host. Back then, I used boot environments "incorrectly". i.e. what I did whenever I performed an upgrade or some test I wanted to be able to roll-back from is this: Create new BE Activate new BE Reboot Do critical stuff Then either roll back to...

    Downgrading 13.1 to 12.4 for fun?

    I'm not sure it's fun, but I didn't think it'd be painful. However, when I went to import my zpool, I got: zpool import pool: zfs id: 1387220501496143749 state: UNAVAIL status: The pool can only be accessed in read-only mode on this system. It cannot be accessed in read-write...

    ZFS ZFS snapshots (parent/child relationship - dependencies)

    I am curious about what happens if a snapshot become corrupted for some reason or another (solar flare who knows!). Does that mean every following snapshot would be unusable?

    ZFS Mounting a partiton of a ZFS poolfile?

    Hi there, I have a file, it's 2 TB in size. The sender said: this is a zfs poolfile. I did setup a Ubuntu 22.04 in VirtualBox, connected the USB drive with the 2 TB ZFS poolfile, mounted it in Ubuntu and typed in: fdisk -l zfsfile01. Ubuntu said: toor@toor-ZFS:/media/sf_E_DRIVE$ sudo fdisk -l...

    ZFS ZFS SLOG Mirror split across HAST and local device

    So, I have been experimenting with methods for providing "clustering" on ZFS for a while now and I recently purchased a Supermicro 6036ST-6L Shared Storage Bus system. It's provides an interesting opportunity as both nodes in the host can share the storage via SAS, and the SAS topology seems...

    Proper mountpoints for ZFS Root

    Solved Question about ZIL/SLOG

    I have been reading about ZFS-ZIL/SLOG, I understand how it works and the benefits it provides, but I am confused when ZIL is used. When an application needs a sync write, data is written to ZIL which if I have understood correctly is located in pool disks, so why don't use the pool directly if...

    I'd like to set up a FreeBSD installation with only my home directory encrypted. I've fiddled with GELI, and I'd like the machine to be one I can reboot remotely, so typing a password in at boot is a non-starter. I'm aware that it's possible to do an encrypted user directory that is...
