As a pre-requisite, consider reading my TrueNAS SCALE virtualization guide! https://www.truenas.com/community/resources/getting-started-with-virtualization-on-truenas-scale.214/ This resource is meant to be a series. Part 1 will cover both the theory behind what I mean by Datacenter-in-a-box...

After participating in this mildly spicy thread, I became aware of that fact that the seemingly innocuous quota is not quite a free way to limit the size of datasets and that unfortunately they do impose performance implications; however, the impact they have on performance can be reduced in...

This amazing document, created by iXsystems in February 2022 as a "White Paper", cleanly explains how to qualify pool performance touching briefly on how ZFS stores data and presents the advantages, performance and disadvantages of each pool layout (striped vdev, mirrored vdev, raidz vdev). It...

Hello, I did have a ZFS pool of 3 HDD (3X3TB => 4TB usable) on a openmediavault install but after some boot problems i had decide to go to freenas. I have a fresh install of the system and the drives are spinning but i have no idea how i can rebuild everything off the drives. Can someone guide...

HP ProLiant DL180 G6 freezed one day, reboted - I get db> prompt. Reinstalled Freenas, can't mount zfs, I get reboots every time I try. Now it's rebooting all the time without me doing anything. Found a thread with the same problem, a man got corrupted pool, but easily restored it, but I can't...

I hope you can help me understand what's going on here with my original dataset using lz4 and the replicated one using gzip-9. Two FreeNAS servers, 1# and #2, both has a new volume with nothing special going on. The dataset in question that is being replicated has all kinds of different data...

I needed to clone a pool from one drive onto a new pool on a second drive. I followed this guide to do this. Now when I try to click any link in the UI, I get a blank page: If I log out and back in or refresh the page, I get taken to this screen: After I choose the correct settings and try...

Hey guys! I recently purchased a Dell r720 off facebook, and now that I am messing with it, I see that the drives go directly from the backplane to a slot in the MOBO, with the raid card beside it. I asked in the LinusTechTips forums if I would be able to just disable the raid card for the...

Hello ix and freenas community! I have been tasked with building a backup storage solution for my family. that includes only devices that connect to the local network. they run linux, android and sadly windows. For that I bought a helios4 and two 4TB Toshiba drives. Because they looked so nice...

Hi, I recently get a HP Gen10 ProLiant Microserver to build a NAS. I bought 4 HDD to build a ZFS pool using RAIDZ, however the write performance is lower than expected. I also tried mirror/stripe, or RAID10, they all seem to have the similar performance, so I wonder the bottleneck might not be...

Hello, I was not aware that the GELI keys are only on the USB stick and in the config backup missing. So I wrote the FreeNAS install iso (about 650 MB) over my boot USB stick. Now I can't import the pool from the stick. I need 2 GELI key files (64 Byte) from the stick. zpool "import -a" and...

Hi, I need to install a new FreeNAS system and I have to virtualise it. I'm using Proxmox as hypervisor and I have both some network storages (which are using qcow2 images) and some local storages which are using ZFS (and virtual machines are using some ZFS drives. I read the information at...

I used to have four drives in a USB DAS configured as a JBOD enclosure. It was managed as a ZFS pool in FreeNAS and served me well until I felt the itch of approaching what my storage paranoid gut felt was "full" storage. My USB DAS didn't have the capacity to hold more drives so I had to invest...

I have attempted to make a backup of a dataset with zfs send. The backup BACKUP03/TANK/library appears to contain over 4 TB of data (just like the source dataset TANK/library). When I do an ls -la on /BACKUP03/TANK/library no files are shown. Has the dataset BACKUP03/TANK/library been...

The volume TooksVolume state is DEGRADED: One or more devices could not be opened. Sufficient replicas exist for the pool to continue functioning in a degraded state. What are the steps to add a new disk that is already in the server?

Despite being new to FreeNAS, over the past few months of use I have really come to appreciate how powerful it is as a storage operating system (in particular ZFS with adequate RAM!). Drive Setup: 6x WD Red 3TB in Raid-Z2 (Half the drives have the 80.00 firmware, the others have 82.00) 4...

Hi everyone, I have seen a lot of posts of this kind on the forum, and even if I've been through some of them, I unfortunnately didn't solve my issue :/ Here is my issue : I have a Freenas running 11.1U6 version I have only one big storage supposed to be sized at 6Tb, and never have I done the...

My sytemboard crashed, so I ordered a new one. It’s a supermicro X10SRL-F with a xeon and ECC 128GB memory. I retrieved the FreeNAS database from my old USB stick, and I have installed FreeNAS and restorored the backup. After a reboot the pools existed. Only there where errors on the POOL and...

I have a FreeNAS box with a 2TB volume and a year's worth of weekly snapshots. How do I move it to another ZFS device? (FreeNAS, FreeBSD etc) Id like to preserve obviusly the data, but all the historical snapshots as well. Im running 9.10.1-U4 Thanks

Hi, I posted this to freebsd-fs but I imagine it's of interest here as well. On one of my systems I noticed a severe performance hit for scrubs since the sequential scrub/resilver was introduced. Digging into the issue I found out that the system was stressing the l2arc severely during the...

Hi there- I've got a new setup with 128GB ram, and I'd like to cap out vfs.zfs.arc_max at around 32GB (I have an 8x10TB RAIDZ2 with ~50TB of usable space). It seems that vfs.zfs.arc_max is set to max RAM - 1GB, and with my rsyncing of data over to this new machine ARC is taking up all the...

Had a very healthy 4 disk, 1 ZFS volume FreeNAS running 9.3 with no problems for years... until a few hours ago when I decided to upgrade to 11.1. Now I get a CRITICAL alert in the GUI "The volume ZFS1 state is UNKNOWN" and the volume is indeed unavailable. zpool import shows 3 of the 4 disks...

Hi guys - I'm trying to work out how to downgrade the pool that was mistakenly upgraded after misunderstanding the Stable flag. I was hoping that I would be able to create a ZFS pool that would be compatible with 11.1 and zfs send to it (if that makes sense) Is that possible, or am I stuck on...

Hi All I noticed from discussions on this forum that @Arwen is using ZFS on her linux laptop, so I decided to give ZFS on linux a shot for my home desktop PC. So far so good, but what about interoperability with FreeNAS ZFS. Since ZFS is coming from two development streams (FreeBSD/Linux...

Hi. This week, I've been lucky(?!) enough that, despite two drive failures in my ZFS pool, I'm managing to save most of the data. I've brought a couple of 8Tb drives and am about half way through copying my data over to the new drives. To save anything embarrassing in future, I want to make...
