zfs

Hello. I've been using FreeBSD on my pc for about a year now and decided to go fully FreeBSD, removing other multibooted OSes from my desktop. Currently I have a single 300GB UFS partition on my HDD that I used as root on FreeBSD. I'm trying to install one 120GB SSD for the OS and two 2TB HDDs...

Hello everyone, I am running a homemade NAS server (consumer hardware with a lot of storage), and I am migrating my data that was all on an external USB disks. I tried out many methods and tests before running a production environment (including installing a base 14.1-RELEASE). Currently I am...

Hi, Currently I have a zpool that does not work anymore. The name of the pool is zroot. The VM was running in FreeBSD version 14.1 and got in a faulty state when the host hang. ZFS is always better then no ZFS (Dan Langeville), I would like to learn from this broken state. The gpart show...

I cannot use the script from ZFS dtrace scripts to print the correct value of zfs_dirty_data_max, and the output is as follows: CPU ID FUNCTION:NAME 2 85224 none:txg-syncing 41MB of 0MB used 0 85224 none:txg-syncing 25MB of...

Have not touched linux (redhat) since right before xwindows was new. My plan is to set up a machine from used parts to work like a file server with a bunch of Raid5 of 4TB spinny HDD's and its main job will just be to nightly make backup copies of my PLEX media repository. But I would like to...

I encountered a boot failure after switching the boot drive from a sata ada0 to a nvme drive nda0 with attaching/detaching, by executing the following commands: zpool attach root ada0p5 nda0p4 # after resilvering done zpool detach root ada0p5 Also, I installed a new ESP on nda0 mount_msdos...

My question is about atime. I have read numerous sources that indicate atime=off is a performance enhancement. Since the device I am creating is primarily a squid proxy server they also recommend "atime=off" for their associated caches and data. Starting here Root On ZFS and continuing with...

I have an application where we run many services in jails. Each service is isolated from the others and keeps its local data in a ZFS dataset that is passed into the jail. We're working on increasing redundancy in the system. Right now we are using ZFS snapshots sent to a backup server to cover...

Hello, How to deal with the situation when the external drive with ZFS was temporary disconnected / power loss. After reconnecting drive: # zpool status pool: zrbackup01 state: SUSPENDED status: One or more devices are faulted in response to IO failures. action: Make sure the affected...

Hello, I am running a small proxmox server with two friends. We each have an individual vm (mine running freebsd, two others linuxes) no complain on that side. I am also running a small shared services freebsd vm that hosts an nginx reverse proxy, a postfix relay and a mediawiki instance. I...

Dear FreeBSD Gurus! Please suggest shell script (probably must be complicated) to remote Installation of the FreeBSD Operating System Without access to a Remote Console. Most of You already read Remote Installation of the FreeBSDOperating System Without a RemoteConsole article, based on Martin...

First a bit of background: This is on a FreeBSD14 relatively older machine (CPU: Intel(R) Xeon(R) CPU E5-2630 v2 @ 2.60GHz (2593.86-MHz K8-class CPU), with a 4 port Gbit ethernet interface (bge1: <HP Ethernet 1Gb 4-port 331FLR Adapter) and 384GB of RAM. a few ZFS pools set on 4x 8TB SAS drives...

Since there is no tutorial how to migrate a UFS installation to ZFS, I'll give my 5-cent contribution. Done this procedure yesterday at my home server that I run several services like Nginx + PHP, Samba, Transmission, Plex, Bhyve VM's, etc. You'll need a new disk that can hold all your data...

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...
