I began to notice very poor performance of my FreeNAS earlier today (taking ~20min to do an rsync dry run that would usually be done in 20 seconds). After trying a couple of times, I discovered that my previously unlocked encrypted volume had locked itself. When I try to unlock it, I get stuck...

I have FreeNAS installed a dedicated HP DL360g8 Server that has 3 x 10TB drives in a RAID-Z1 configuration, and I have an SSD as cache. I do have De-duplication turned on as I'm copying nightly system images to the appliance. The Server has 128GB of memory and the Storage Pool has 15TB of usable...

I just set up a new replication server, and have been testing it. My main server and this are both using 11.1-U5, both enterprise hardware, and all features enabled. I ran zfs send on the main server and zfs receive on the new backup server, and deliberately killed the process after a while to...

Buongiorno a tutti! I have created yesterday my first iocage (GitLab) and everything works perfectly! I have noticed only now that the iocage root is in a pool that i don't want to use for that. I'm trying to moving the existing jail and the root to a new place. What I'm not sure is what...

I needed to clean up some space, because volume has hit the 80 %. So I started to delete a lot of large files, which I didn't need any more, like large downloads etc. After that I noticed, that little to none space was freed through this. So I thought about snapshots. Listing the snapshots in...

Hello, I have a pool on a general file server with 6 x 2TB drives configured in a three-group mirror that are very old. The system, for all intents and purposes, appears to be working normally. The pool does not report as degraded. However, I have been trying to move certain files using rsync...

Hello! There was power outage. After that FreeNAS does not starting (shows both in normal and verbose mode) RAID configuration is Ok, all disks are online I've only found this topic https://forums.freenas.org/index.php?threads/workaround-semi-fix-for-mountroot-issues-with-9-3.26071 but I...

Hi! I'm about to redefine my humble NAS/Media/Fileserver and would like to get suggestions regarding how to arrange/split this bunch of disks (all of them inside the same system/case): SEAGATE SATA 3.5: 8 x 4TB 2 x 2TB 1 x 1TB 1 x 32GB 2.5 SSD Excluding the obvious choice of the SSD to the...

This probably has been addressed before, but I can't find it any place. So please forgive me if I'm asking for something that's already been discussed elsewhere. I am finalizing my first DIY home NAS, which will be used primarily for media streaming (via Plex &/or Kodi) and for storing a...

I'm hoping that someone who has some experience with snapshots can help me. I have saved a number of snapshots of datasets from pool TANK using zfs send/receive to a removable pool BACKUP01. (TANK has grown too large for a single backup volume, so I need to back it up in pieces.) NAME...

I'm running FreeNAS 11.1-U4 and I'm using the iocage jails. I used the (new) UI to create the jail. I used the command line to enable and add a ZFS data set to my jail, which has no mountpoint inside it. This is perfect for what I want. Now, I go to create a new data set and have it be /web on...

I know it is syntactically OK to use _ and : in snapshot names, but is it likely to break anything in FreeNAS? I'm writing an external backup utility and I'd like to make snapshots with the following format TANK/DATASET@__BKPVOLNAME:YYMMSS-HHMMSS so that they are easy to parse/scan for. Any...

Hello Noobie here, I've done some reading up on raid and FreeNAS and still have so many questions. I'm an IT network engineer so considered a geek but I've never really dug into building raid before. My plan was to rebuild my unused Windows 10 home built desktop into a FreeNAS, as its only...

Hi All TLDR; I'm hoping someone can tell me if I've found a bug, or if I'm doing something wrong. I have two directory trees with almost exactly the same data, and I don't seem to be getting any space savings. Only 2 of the almost 4700+ files in each directory tree differ. All other files...

Here's what I have tried, to get owner inheritance working on my dataset. man zfs says it works for zfs if the setuid=on property has been set (although man mount says that it isn't available except for UFS?) Test results shown below with comments interspersed. Looking for feedback if this is...

Hallo everybody, I just Built my own FreeNAS Server With the following components: - 32GB Reg ECC RAM (RDIMM) By Kingston - Intel Xeon E5-2620 v4 - Asus X99-E WS First of all i just want it to use as a file server to store all my data and protect them against bit rot (and I’m also running a...

So I was trying to reinstall Radarr on my NAS as my previous version had broken when i updated some of the packages. After messing up with the install for the first time i tried to delete the jail in the iocage folder via ftp then removed the dataset via the WebGUI. After removing the jail, I...

I have a newer, HP ML10 server with a couple of LSI SAS2008 cards connected to an external case full of newer 2TB to 6TB drives. Pool is organized as 5 vdevs of mirrored pairs. I have a very old IBM rack server at another site with two of the same LSI SAS2008 cards and I use zfs replication to...

Hello. Recently I had 1 drive dead in my pool. In addition to dead drive - wrong drive had been pulled from live storage. Then good drive had been pushed back and bad drive replaced. Although - pool now can't reconstruct itself. But, luckily (hopefully) - it is a mirrored RAID10 and all those...

I have a Samba share with ACLs used to control access to the files. There are two groups - let's call them "ordinary" and "admin" users - I want the admin users to be able to see and browse certain old snapshots, which I've set to be shown by default in ZFS properties, and removed from veto...

This is a complex area where 4 FreeNAS subsystems overlap - ACLs, ZFS pool structure, ZFS snapshots, and Samba shares. I know what I'd hope to be the expected behaviour, but I'm pretty sure it doesn't work that way. I'm posting this to get a good understanding how it does work, and to learn what...

Hey guys, been a long time ZFS and FreeNAS user. I also have used ZFS on ubuntu 14.04 for a few years but now I want to convert that system over to FreeNAS. Can anyone give me a best practices way to import the pool from my ubuntu install? Thanks in advance. chris

I was doing some copies between SMB shares on a Windows client machine... and a Windows installer was running in a Bhyve VM, when my FreeNAS became completely unresponsive. I couldn't SSH into it, access any shares, or interact with the web GUI at all. So I did a hard reset. When I booted back...

There's a thread a while back, which asks about what happens if something temporarily renders multiple HDDs in a pool, unavailable (but undamaged). Examples might be, a non-redundant HBA/backplane failure, some kind of federated or linked enclosures/pods/backends get their cable pulled, some...

My ZFS is in a bad place, and I'm out of ideas on how to fix it. Short summary: I'm running RAID-Z2, 6x3TB drives, running under encryption through FreeNAS's geli layer. After moving, I unboxed my server and powered in on - all's well, went to my folks' for the holidays. Remotely, I notice my...

I thought the community might benefit from this, so I decided to write it up and post it. I'd be interested in comments from those with a lot of ZFS experience in a wide variety of use cases and data types. I decided to do a bit of investigation on the possible reduction of disk usage by...

I am attempting to create a removable backup system that will replicate my datasets to removable pool in a hot swap cartridge. After spending hours with the man pages and online research, I still need a bit of help. I've tried to answer my own question below to the best of my ability, and I'm...

Does anyone know what this message actually says? Is there a hard drive which is failing or is it just regular volume scan? Problems started yesterday when I rebooted my FreeNAS. The hardware I'm using is HP Microserver gen8, 8GB RAM, 2TB+2TB+8TB. https://i.imgur.com/kdhLhCi.jpg Update1: I was...

So i have (luckily) just a few files, that for some reason start with a leading space before the actual alphanumeric sharacters start being used. These files being torrents, i couldn't figure out why my torrent client didn't recognize them when checking. I did notice there's a difference in a...

Section 1.1 of the FreeNAS guide mentions four filename/path length limits for the current version. The first is accompanied by an example, the second is clear from description, but the third and fourth aren't very helpful: which to me are not exactly clear. It would help me a lot to have an...

Hello all I need some help. After updating to FreeNAS (11.0-U4) I started getting a strange error. When my box tries to mount my ZFS volume I get (KDB enter panic). I will add a screen shot below. I backed out to 11.0-U3 and am able to boot up no problem. Any ideas what may be causing...

I want to expand my main pool (TANK) from 4 disks to 8 disks in RAIDZ2 which if I understand correctly means that I need to destroy the pool and restore the data. I created a backup by using the the automatic snapshot function and then a zfs send/receive from the command line. The following...

Hey! Question about accessing data. I'm running FreeNAS-11.1-RELEASE and I have one VM, a Ubuntu 17.10 Desktop. In this VM, I want to mount data that I have on the same FreeNAS installation. Now I do this in Ubuntu with CIFS and I have a CIFS (Windows SMB) share in FreeNAS. Works great. But I'm...

I've just setup a new machine with FreeNAS 11.1 32bit (hehe, just kidding) and I see by default the root dataset has atime enabled. My question is: what might break if I disable atime there? I'm going to create child datasets for different shares/users anyway and frankly I'm not going to...

Hi, Since I implemented snapshot on my freenas server, I have always been scared to rename a file because i'm not sure if it would double the disk space needed. After a quick search on google it look like it's too dumb as a question to appear on any thread... Does renaming a file increase the...

I have 2 replication tasks. The first is runs every 5 minutes to another FreeNAS server in same DC, the second task runs every hour but with a slower connection offsite. When the second task is running, the first task is waiting. Is it possible to run ZFS replication tasks simultaneously?

Hello FreeNAS community, I am looking to move my samba server off my home router and on to a more powerful machine. I have a HTPC in my house that run 24/7, and would like to give it the job of acting as a server. Specs: intel i7 4770k 8GB RAM 3TB storage 1 onboard NIC 120GB ssd for windows...

My pool contains a mix of raw devices (/dev/da...) and GPT formatted devices (/dev/gptid/...). I am trying to upgrade a mirrored vdev from 2 to 3 disks, and ZFS isn't having any of it. I can't figure why. The disk is da4 and the vdev I'm trying to add it to is listed as "mirror-2", containing...

Many of us run ZFS for myriad purposes. For those who use it in DCs or “work” purposes, I salute you, but this thread is for media enthusiasts who love ZFS for many of the same reasons, but have very different workloads. I imagine an ARC that is told to load files in anticipation as I and my...

480GB Samsung SM953 NVMe SSD with PLP: Just picked up this beaut today, it's an enterprise NVMe SSD with power loss protection. Check out the pics, you can see the honkin' capacitors on the front and back. I was thinking of partitioning it and using somewhere between 8-24GB for the SLOG and...

All, I am running FreeNAS-9.10.2-U6. I took a recursive snapshot of a data set and did a zfs send | zfs receive to an external / USB drive. When I try to do the reverse send / receive to pull the snapshot back to the main data set, the process runs for awhile, but towards the end the system...

Here are the drives I have at my disposal. I have 3 machines each capable of holding a max 12 drives. Currently I have 12x2TB drives in a Raidz2 which is ok but performance is lack luster. Most of the files are videos and are not accessed often. My current archive is 12.3TB and I would like to...

I'm being affected quite badly by this known FreeBSD ZFS tracked issue which is related to statfs + this issue + this, when using my FreeNAS box. Unfortunately I'm not clear about what must be avoided, to avoid triggering the issue, or how to identify existing snapshots or nested datasets that...
