Hello, The title says it all. In TrueNAS Scale, I have a 2 drive mirrored pool for testing, with more to be added when the drives arrive. I am seeing 270MBps transfers until the cache dumps and then the transfers dip to below 100MBps and sometimes go as low as 30 or 40MBps. They never...

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...

To my surprise I discovered today that 3-way boot mirrors are not supported in 11.1-U7 Exception Type: MiddlewareError at /system/bootenv/pool/attach/ Exception Value: [MiddlewareError: [EFAULT] 3-way mirror not supported yet] Booting off USB is useful because it uses "free" external USB...

I am not sure if this is normal but i run several freenas units that are configured with mirrored volumes and i run freenas replication to other units that are configured with Z2 volumes. the problem have is that the space from the mirrored units doubles on the Z2 units, when i replicate the...

Hi, Server for FreeNAS: HP ML 350 G5, controller e200i (each disk as RAID0). Disk: 8 x 300 GB SAS. Destination: iSCSI for VM. It is better add all disk to pool, example: - RaidZ2 => (8 x 300) - (2 x 300) = 1800 (two disk can die) - RaidZ3 => (8 x 300) - (3 x 300) = 1500 (tree disk can die) or...

I have roughly 1TB of data in my old NAS which run 2x2TB in RAID1. Now I want to move those drives into my new FreeNAS system. Unfortuantely I don't have a third device onto which I could copy before reformatting the drives for FreeNAS. The only solution I can currently think of is to only...

Hi everyone, pardon my questions if they're basic but despite my extensive searches I'm still new to Freenas and raid formats. I am trying to achieve the perfect balance of redundancy, performance and safety in a home-enterprise environment. My issue: the place I live in (Philippines) has...

I'm pretty good with windows, but a noob in linux etc. While I've read several explanations, I do not adequately understand vdevs, pools or ZFS. I currently run a 4TB + 1TB HDDs as a spanned volume on windows 10 as a home server and run a backup weekly to secondary drives all over my network...

Good morning, As you may know, I have decided to upgrade my home system to a X10SDV-7TP4F motherboard that features two SATADOM connectors. I currently possess the OEM-supplied SATADOM (32GB?) that came with my Mini XL as well as two new 64GB Supermicro SATADOMs that I would like to use with...

Hello! My setup is the following: 1 vdev with 3 HDDs, all 3 mirror of each other (so 3 x 3TB HDD, total available space = 3TB). 2 Drives are just going to spin all the time, mirror of each other, that's the redundancy. The 3rd drive, I'll plug it in once every now and then (say: once per month)...

Boa Tarde Gostaria de saber se alguem ja fez espelhamento entre freenas Tenho um servidor NAS ativo , queria que o mesmo fosse espelhado para outro servidor completamente ou somente os dados e possivel ????????? Teria algum tutorial

I have a freenas-boot / stripe / da6p2 boot device (usb stick) working correctly. I have inserted a new USB device "da5" correctly detected (note: I tried all USB ports of my computer). glabel status returns (I removed other disks): gptid/a0daaf02-7e84-11e6-a889-78e3b5ce431f N/A da6p1...

So I came across an article the other days about mirroring your FreeNAS boot device, especially if you are using a USB stick as your boot device. Well I am, so I thought I had better. :-) So I go down to the local stationery store and pick up a second 16GB USB stick. I get home plug it in and I...

I am running FreeNAS 11 and am having trouble configuring a cron job rsync back up of an entire Volume (/mnt/NAS1) to a folder on another volume (/mnt/NAS2/BackUp). Originally the script was only backing up a folder on NAS1 but now i wish to mirror the entire volume on a schedule. Here is the...

Bonjour, Je souhaite éclaircir ma lanterne sur ZFS et répondre à quelques doutes. J'ai un ZPOOL nommé Miroir014TB composé actuellement de 2 VDEV comme ci-dessous: % zpool status Miroir014TB pool: Miroir014TB state: ONLINE scan: none requested config: NAME STATE READ WRITE...

Hi all, So, after a few years of not using FreeNAS I want to get back to using it, properly. My situation is this: I am an audio engineer with quite some data storage needs which all need to be safely backed up. I'm of the type that likes to store things in three different places, one needed...

Hi, I have been considering an unconventional arrangement of three mirrored vdevs, each containing a 6TB hard drive. Would such a configuration have lower ram requirements than some of the typical RaidZ, RaidZ2, RaidZ3 configurations, or are the memory requirements dictated only by drive size...

Build: FreeNAS-11.1-U4 Drives: Seagate IronWolf 4 TB Number of drives in zfs pool: 2 Pool type: Mirrored Description: One of my two drives needs to be RMA'ed. The two drives are mirrored in a ZFS-pool. It it possible to remove the faulty drive (putting the faulty drive into offline and...

Hallo zusammen, ich habe mir vor kurzem ein FreeNAS (11.1) System zusammengestellt und muss sagen, es läuft bisher alles einwandfrei, sogar noch besser wie ich es mir vorgestellt habe. Aktuell laufen bei mir Testweise 3x500 GB Platten in RaidZ1 (Raid 5). Mein FreeNAS System besitzt 16GB ECC...

I've got two volumes on the same FreeNAS 11 box that use HDDs for data storage: -- #1 is a 2 drive mirror using 5 year old WD Se 4 TB HDDs (WD Se was the predecessor to WD Red Pro) -- #2 is a 2x2 mirror (like a RAID10) using brand new WD Gold 10 TB HDDs Both are set up the same way with full...

Hey, I have a 3TB mirror array but it after reaching the 80% usage limit. Im just wondering if i was to add another 1 or 2 disks to the array could upgrade it to a RAIDZ1 or RAIDZ2 array or will i have to copy everything off an create another array from scratch? If yes, how would i go about...

Freenas 11.1 - I have been trying to mirror my USB stick boot drive. I have a larger drive (64GB) than the original (32GB) and I have followed the procedure several times - System/Boot/Status/Attach with no joy. When I click the button it seems to think for a bit and then the window closes and...

In preparation for upgrading to FreeNAS 11, I am in the process of migrating from a 16GB RAID1 pair of USB boot "drives" to new 64GB USB drives. The plan was to clone my old 9.3 install onto the new drives, remove them, and then upgrade, so that if all goes horribly wrong :) I can just go back...

Hey Guys! I'm helping a friend build a FreeNAS for Media Server. The specs: CPU: Intel Core i3 - 4170 3.7GHz - Dual-Core Motherboard: ASRock - E3C226D2I Memory: 16GB ECC Case: Fractal Design Node 804. PSU: Corsair CSM 650W Gold. Fans: 2x Noctua 92mm, 1x Noctua 140mm Storage: 1x SSD Kingston...

I'm quite new to FreeNAS and I'm perplexed by an issue I'm having with a mirror of two 8TB disks. If data corruption occurs on one disk, shouldn't FreeNAS automatically correct it using data from the other disk? Why is it stating, "Permanent error have been detected[...]?"

So in my messages this pops up: WARNING: Oct. 2, 2017, 10:20 p.m. - New feature flags are available for volume freenas-boot. Refer to the "Upgrading a ZFS Pool" section of the User Guide for instructions. I then go to the Volumes, select freenas-boot, it show's the upgrade button. I...

Hi, i have a HP ML10v2 with the following specs: Intel Xeon E3 1230v3 16GB Kingston ECC Onboard sata controller in AHCI 2x2TB WD RE4 8GB Kingston USB2.0 (FreeNAS) i installed FreeNAS 11 on the server (after applying the latest SPP for the server) and set up both 2TB drives in a mirror. i...

I have a FreeNAS Mini (4x HDD) with 4x 3TB drives. It's supposed to be setup as a RAID 0/1 striped mirror: 1 mirror extended by 1 mirror. I'd expect this to show roughly 6TB of disk space, but it shows 3TB leading me to believe the second mirror is a mirror of the first instead of an extension...

Hi, I'm using 256 GB Sandisk SSD for the jail, But now I want to create a mirror for it. As you may know this is very easy with boot volume. Just add another usb and use attach command and voila, now your boot volume is mirrored instead of a stripe. Now is there any easy way to do this for...

Hello, right now I am using a NAS with four Bays. Three 4 TB disks as encrypted mirrors. I would like to switch this setup in the following way: 1 zpool consisting of 3 mirrored disks --> 1 zpool consisting of 2 vdevs. Each vdev as its own 2 disk mirror. I know that you cannot remove disks...

I currently have a RAIDZ1 made up of 4x2TB drives. I've recently decommissioned an old 4Bay NAS that also at 4x2TB drives in it. I've mounted the new drives and they are ready to go, what I would like to do is take these 4 drives and make it a mirror of the existing RAIDZ1 set. Is this...

Hallo Leute ich wollte mal fragen wie ihr ein delayed Mirror aufbauen würdet? Von Haus aus bietet Freenas das ja nicht an und bei Google werde ich auch nicht wirklich fündig. Also hab ich mich selbst mal daran versucht was in Bash zu schreiben. #!/bin/bash now=$(date +"%Y_%m_%d") zpool import...

Not sure what's going on. I have a mirrored pool, and created a 3TB zvol on it as an iSCSI target. But when I connected to it from Windows 8.1 (as a test), it was exposed in Windows iSCSI Initiator control panel and in disk management console, as 2 separate 3TB disks - presumably somehow...

For added availability I'm considering building a RAID0 pool on top of several 3 way-RAID1 vdevs built with 4TB hard drives. However I'm wondering : - Will the read performances be better compared to a 2-way mirror ? - What if a second drive fails in the same vdev during the reconstruction ...

I've tried to research this but can't find an answer, with luck someone here will know. My new server will have its pool built as a set of mirrored HDDs. I would want to stick with mirrored HDD vdevs, or at most mirrored 2-way stripes, rather than RAIDZ, due to read+resilver speed/resilver...

So I want to know if this is possible and whether or not it's a good idea. So let's say I have a two drive mirrored array. Can I attach a third drive to the array, sync all the data so it becomes a three drive mirror, then detach the third drive so I store it separately as backup? Would this...

Hi thar. Bear in mind that I am relatively new to NAS in general :confused: I installed FreeNAS on a 3 SSD-disc setup. Installation went smoothly, and was easy and quick to set up for web-interface. immediately when engaging the interface, I had the option (from the Wizard) to set up my disks...

Hello. First time poster here on this forum. I've been using freenas on and off for quite a few years and moved my home storage array to freenas full time now as my sole array. Looking for some help with figuring out what or even if something is in fact wrong with one of my pools. If i posted...

Ive read a few posts indicating that raidz1 is not preferred on large drives due to failure rates. However i think i have read that mirroring is ok. Can anyone explain why? Is mirroring more reliable somehow due to the way resilvering works? Right now i just have a pair of drives, but when i...
