zfs

first part of my zpool administration infographics is ready, i hope it helps. modified as per suggestions..

All, Looking to implement a dedicated server to perform data processing/analysis and it needs some fairly significant I/O. The "twist" is that the data's lifespan is the duration of time it takes to import, process, analyze and report on - then the database and the data is deleted. Storage...

I discovered on BTRFS a metadata bloat problem. Basically, I copy an nspawn container folder (several gigs), and the metadata usage gets bloated by 115MB. As it's CoW a typical user would expect almost no extra space taken by this action (even being remotely aware of some overhead) and will not...

Hey folks, I'm migrating a server to OpenZFS. I mounted the /poudriere dataset to another disk/zpool. My question would be whether it is worth creating a /ccache dataset, or whether to create /ccache on a UFS disk. I just have 8GB RAM. Would a /ccache dataset be too overwhelming? Or a simples...

Hi all, I am trying to create an encrypted zfs volume that will be auto-mounted using a keyfile. According to online information this should be possible with the following command: zfs create -o mountpoint=/home/ -o encryption=on -o keysource=raw,file:///usr/local/homekey disk/home However...

Hello, I am considering migrating a few VMs to a new hosts and would love to make it a freebsd one. I am not sure however of the best way to set up storage. From the Handbook I read that using ZFS on the host and ZFS volumes for the guests would be optimal. But a blog post from vermaden tells...

I'm about to set up mysql on a machine, and I know that in the past I've read about setting up specifically tweaked dedicated zfs datasets for it. I've never done that for mysql before, but I figure now if ever is the time to try it out. So, I searched for info about this to refresh my memory...

So I installed a fresh system using ZFS with my home directory at /Users/joshua (I'm also a MacOS user so it feels familiar lol) and I noticed that /home still exists and is set in zroot. I suppose that's normal because the system probably assumes that other users would have their homes there...

We have 3 servers with ~40 jails on each under CBSD management. Each jail running our perl application. We would like to share installed packages, binaries, installed perl modules across jails. Plain is master jail as a base image jails for application created via `cbsd jclone` , then via ZFS...

Hi, I'm on 14.0-RELEASE and wondering if that is intended behaviour. I have an encrypted dataset with "sharenfs" property set (and indeed intent to share once mounted) but after loading the key and mounting, the dataset is not automatically exported (/etc/zfs/exports is empty) so I have to issue...

Hi, my ordeal continues. I was trying to install FreeBSD 14 bare metal but had a host of issues with that that didn't work, so I installed 13.3 to Virtual Box in Linux and passed over a hardware usb dongle with an NVMe U.2 drive connected that I want some data off of it. (Backups were only...

on 14.0 after a $ zpool status indicating "unactivated features" and a $ zpool upgrade -a (if I remember correctly) the machine suffers from amnesia. what can I do to recover? what did I do wrong?

This is a strange one: I've recently reinstalled FreeBSD 14.0 on an old, non-mission critical PowerEdge R710. Two zpools were created, zsystem and zdata. Since the old BIOS doesn't give me a JBOD option, the pools were created with megaraid virtual devices all attached to the same controller...

The following is the zdata array in a FreeBSD 13.2-RELEASE system: HD Device Passthrough Device Serial GPT Model Firmware Slot # mfisyspd0 pass0 V8H9UVMR data_disk11 HGST HUS726T6TALE6L4 40H 0 mfisyspd1 pass1...

I had a hard time describing this problem succinctly to generate a title. Thanks also for your patience, as I am not a professional sysadmin but a scientist. The bottom line is that my 4U JBOD power-cycled (or the controller dropped it) for some reason. When the disks came back online, there...

I am having issues with my upgrade to 13.2 from 12.4 and would like to revert to my previous version of FreeBSD for note-taking and attempting a new update from scratch as I cannot get my jails to run, I cannot get VNC or Xrdp to run at startup. I am a little gun shy as I am not sure why my new...

I have a Sabrent 4 disk dock with spinning disks and ssds for game storage on my system. When I have the dock turned on at boot the boot fails. I initially, per the handbook, had all drives in fstab. I have since removed them and created a mount script to load after boot. Is there a way that I...

i have a zfs video dataset that is mounted in my home directory, and i want to mount it using nullfs to the video directory in a Linuxulator chroot i can manually mount the directory from the host into the chroot the issue is the zfs datasets are mounted later in the boot process than the...

Introduction: This is a guide on how to dual boot windows 11 and FreeBSD 14. I recently received a fantastic laptop that happens to be surprisingly compatible with FreeBSD, so I highly recommend it, and no, I am not sponsored by MSI; I have merely fought enough laptops to recognize a keeper when...

Hey there, we have a strange effect. After some time (weeks) the ALLOC raises quite high (here >50GB) over the real file usage. System commands like du and df showing always (nearly) the right usage of the dataset, butt the ALLOC and AVAIL space going completely wrong. See outputs below: vsd --...
