DISCLAIMER: Introduction After a successful installation of FreeBSD 14.0-RELEASE on a Dell OptiPlex Micro (MMF) 7010 (GPT+ZFS on NVMe SSD) I felt encouraged to do the "same" on an older Dell Vostro 3470 of mine which was running a fully updated FreeBSD 13.2-RELEASE. The system uses UEFI...

I have created a HowTo about using ZFS inside a jail with AppJail: https://github.com/DtxdF/AppJail/wiki/zfs

Hi. I have hard drive called ada0, it does get mounted on boot but it doesn't show up in gpart show command. It has a zfs pool on it called wdc, when I export this pool, it shows up on gpart show command and there is saying CORRUPT on the ada0. I tried using gpart recover ada0 twice, it works...

I've been happily using 13.2-RELEASE for a while, with ufs filesystem Now planning to setup a fresh14.0 system on some old~ish hardwares, likely a combination of modest SSD and a single spinning drive. 14.0 system will just be used for a simple desktop, and various small projects. Most likely I...

DISCLAIMER: The beginning of the story I've got a new hardware, Dell OptiPlex Micro Form Factor 7010, on which I was willing to perform a "relatively minimal" :-/ FreeBSD 14.0-RELEASE installation. After having successfully created & tested the "recovery media" following Dell recommendations...

I used iocage export to transfer a jail from one host to another host. The jail's export files were transferred using rsync. However, I cannot get iocage to successfully complete the import on the destination. This is apparently caused by running out of swap space. Dec 13 12:20:11 vhost03...

New to ZFS, and wondering what exists in BSDland to easily create a bootable .iso image and spread the goodness. I've been using clonezilla for years, works great on UFS filesystem, but not so much anymore as I just learned clonezilla does not support ZFS. The only thing I can think of would...

The internet is filled with how to guides on zfs and so is youtube. I saw the handbook part on zfs but it only scratches the surface. I want to basically keep a backup of my laptop that is running zfs i only have USB drives so i would like to mirror what is only my laptop so if something...

Hello! I've had a little mishap :oops: So far nothing bad happened. The initial situation: I have the following hard drives installed in my PC. 2 TB NVMe (EFI boot partition and the rest Windows) 1 TB NVMe (NTFS formatted, data grave) 2 TB SATA SSD (FreeBSD-ZFS and FreeBSD-Swap) 1 TB SATA SSD...

I use ZFS snapshots and mirroring (both on a harddrive that is permanently connected and on harddrives that aren't always connected) as a means of keeping backups of my data. Using the snapshots, I can go back in time if I accidentally delete files or something else happened to my data on the...

14.0 shipped with ZFS 2.2 and block cloning disabled (behind a sysctl). ZFS 2.2.1 was just released with the same (default to disabled) change, due to corruption issues people are running into. It appears there is still a bug that can be hit with some combination of sysctls. I would recommend...

Dear Everyone, The release notes for 14.0-RELEASE state, "After a system upgrade, but before doing a zpool upgrade, the boot loader on the ESP must be updated, or the system may become unbootable." My question, in great brevity, is, "How?" (when the system is purely UEFI GPT) Having looked at...

Hello there. Just upgraded from 13.2 to 14.0 RELEASE, via freebsd-update tool. I guess I manually need to execute command for ZFS update/upgrade, after FreeBSD upgrade from 13.2 to 14, right? I'd like to be careful on this step because this is a remote dedicated server with no physical access...

In /etc/defaults/periodic.conf, there's this part about periodic ZFS scrubs: # 800.scrub-zfs daily_scrub_zfs_enable="NO" daily_scrub_zfs_pools="" # empty string selects all pools daily_scrub_zfs_default_threshold="35" # days between scrubs...

In /etc/defaults/periodic.conf, there's this part about daily ZFS backups: # 223.backup-zfs daily_backup_zfs_enable="NO" # Backup output from zpool/zfs list daily_backup_zfs_props_enable="NO" # Backup zpool/zfs filesystem properties...

Hello, I'm trying to create a FreeBSD/Windows dual-boot setup on one of my machines (I know, I know, but I need Windows for certain tasks at my job). I have done this before by installing Windows first, leaving some free space, and then creating zfs-root and zfs-swap slices/datasets by hand in...

Hello to all, unfortunately I'm facing infamous messages when booting, when I'm trying to recover friend's NAS, which I installed last year. zio_read error: 5 ZFS: i/o error - all block copies unavailable ZFS can't read MOS of pool zroot It seems, it reaches up to stage 2, but gptzfsboot...

For various reasons including regulatory compliance, I would like to have a Write Once, Read Many (WORM) storage partition and wanted to know if ZFS can enable this.

With the release 14.0, I plan to switch to FreeBSD as my main OS. Unfortunately, some of the programs I use work only on Linux, so I will still have to boot to Linux from time to time. I am wondering how to structure my storage. In my notebook, I can place 4 disks in total, 3 SSDs (2 NVMe M.2 +...
