zfs

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...

Hello. Trying to install FreeBSD 13.1-Release (FreeBSD-13.1-RELEASE-amd64-disc1.iso) with configuration: Partitioning: Auto (ZFS) Partition Scheme: MBR (BIOS) Pool Type/Disks: stripe: 1 disk And I found that after the first reboot the system does not boot and a message is displayed: "Missing...

This morning I got an automated email from my ZFS server that's going to demand my attention for a little while: [sherman.149] # zpool status zroot pool: zroot state: DEGRADED status: One or more devices has been removed by the administrator. Sufficient replicas exist for the pool to...

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...

I recently changed my root ZFS from a mechanical HDD to a smaller SSD. I did it with "syncoid" as syncoid -r zroot zroot2, but some mountpoints were not preserved. But I think my mountpoints are messed up, here's what they look like: zroot 101G 107G...

Hello, I found myself in a situation where I don't know where to start. I have a 3,5" spinning rust disk placed in an external USB enclosure. I am using this disk for backups (I am learning how to do this nicely and automatically via zfs export | zfs import and a bunch of scripts). The problem...
