zfs

Hi everyone, I created a new ZFS dataset root@vieron:~ # zfs create zroot/playground root@vieron:~ # ls -ld /zroot/playground/ drwxr-xr-x 2 root wheel 2 Mar 17 12:40 /zroot/playground/ and assigned read and write permissions to the "labgroup" group root@vieron:~ # chmod 775...

Hello everyone, I wanted to share an article that I recently wrote about migrating from Proxmox to FreeBSD's bhyve hypervisor. The article covers the process of migrating virtual machines, storage, and networking from Proxmox to bhyve, and includes tips and tricks that I learned along the way...

Hi, I have set up zfs send | zfs recv replication as an unprivileged user. The purpose is to have an off-site backup process that is a) fast, and b) secure, in the sense that a successful cryptolocker attack on the primary backup would be partitioned off by the dint of append-only replication...

I have the GELI key, but the associated pool (HDDs) unavailable currently (phisically). Can I check my password(s) with the keyfile only, without the encrypted media? If I know, the keyfile contains the keychain(s), protected by password(s). I would like to check this password, but without...

I am dual booting NixOS in the same zfs pool with FreeBSD. What would be the best way to export the root pool during shutdown automatically?

Hi! First of all, I am complete newbie in FreeBSD. I would like to install FreeBSD on ZFS. Modern installer have everything to install FreeBSD on ZFS without any problems, but I have a one "Ideafix", if you know what I mean. I want to remove Boot and Swap partitions from ZFS pool(RAIDZ1) and...

Hi All. I got a system problem since FreeBSD 13 as follows (Prior 12, I have no impression about the issue). Jan 30 11:22:47 test kernel: [116123] pid 50340 (mysqld), jid 1, uid 88, was killed: a thread waited too long to allocate a page Jan 30 11:22:47 test kernel: [116134] pid 32665...

Hi, I want to learn about how exactly boot process of FreeBSD 13.1 with GELI + ZFS on Root on UEFI works. I read about loader, UEFI, geli and, still I can not understand it. Also I have some more specific questions too: I have two partitions. EFI and ZFS. The whole root filesystem is in ZFS...

Hi, On this forum and on internet many things are found about GELI. What I was looking for is: - That GELI boots from the local disks on the machine - It works with a passphrase and a keyfile. - The keyfile is located on a USB I have the impression this setup is not possible, but I want to...

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...

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...

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...

Hello, I have to create an encrypted dataset, my configuration is as follows: freebsd-version -ukr 13.1-RELEASE-p3 13.1-RELEASE-p3 13.1-RELEASE-p5 zfs version zfs-2.1.4-FreeBSD_g52bad4f23 zfs-kmod-2.1.4-FreeBSD_g52bad4f23 and I would like the key to be on a remote server, for this and...

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...

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...

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...

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? What is the parent/child relationship? What is the safeguards in place to help prevent this? If this is the case would...

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...
