Hi, I have a warning and I don't know what it means. It sounds that it's related to my iSCSI drive and the fact that my FreeNAS crashed 6 hours earlier because zvol where iSCSI was out of space. Would someone help me understand the below and if I should be concerned? > SMP: AP CPU #3...

Hi, I have a pool with a single vdev with three 240gb ssds in raidz1 that I use for primary storage for ESXi. The problem is that I want to use as much space as I can but freenas doesnt let me create more zvols in the dataset because it says its full. According to the zpool I used 345GB of...

Hi everyone I am new here and I don't usually do this forum thing. I would like to more, but I just can't ever seem find the time. However I have no choice in this case because I believe this is the only place I can find the answer I need. I am setting up a small group of VM's on a 14gen Dell...

Hey, I've managed to setup my FreeNAS server for iSCSI and connect to an ESXI server. The FreeNAS Device shows up but when I go to create a datastore is errors unable to change host config. FreeNAS Server: FreeNAS 11.2-U5 Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz 32Gb RAM 16Gb USB - Boot Drive...

I am replicating a small zvol containing a hyper-v VM that has been running off my primary FN 11.2 box on to a secondary. I need to now mount the replicated zvol in Windows but when I try to initialise the disk I get a write protected error. I remembered from one of the tutorials that...

Edit: I saw someone mention in another thread that a simple dd if=/dev/zvol/storage/virtual_machines/Arch_Linux-hfs0ap of=/dev/zvol/flash/virtual_machines/Arch_Linux-hfs0ap should work and it does, one caveat is that you need to first create the zvol in the other pool before you start dd...

Hi I have a couple of Linux VM's and I believe the drives their zvols are stored on may be failing. These are SSD and they pass all the regular SMART based read tests so write tests will be needed in order to verify that they still work. However I was wondering how I can move the zvol's to...

Hello, I have two Freenas storage servers, old one using iscsi zvol used by Xen server with 3 luns , new Freenas storage ,instead of zvol decided to use NFS to store all vms. My issue is when i try to migrate all vm from iscsi to nfs , while trying do it directly from Xen console its fails , so...

Hi I create a Powershell module to configure Freenas with API I have one problem to create an extent with a ZVOL This picture show to Extent the first Extent with the ID 1 is create with the Web GUI and the second with the API and my module. When I look the documentation for the API freenas...

Hey all- Running FreeNAS 11.2-RELEASE. I've got a 51TB RAIDZ2 (10TB x 8) and I'm trying to create a 10TB sparse ZVOL to host a Windows Server VM. I'v got 38TB of free space. I tried creating the ZVOL under Storage > Pools under my "vm" dataset (which is hosting a few other zvols currently), but...

In 11.1U6 if you expand a zvol that is presented as an iSCSI LUN, the new size is not reported until the iSCSI (ctld) service is restarted. Can anyone confirm if this is still the case for 11.2? I know I could test this in a VM but I'm lazy/busy/either.

Hello folks, Is there anyway to look at the contents of a zfs volume from within Freenas? Is there a way to mount a zvol from within freenas, if so can someone post the syntax, the normal Linux "mount -t ..." didn't seem to work, I have been through the zfs man pages a number of times and...

Hello Ladies, Gentlemen, I use to work with NatApp/IBM storage appliances, so I understand the matter a bit. I'm not new to FreeNAS, but it has been a while since I used it. (9.3). Installed it a few months ago (april), and it serves us well. Now, one of our subpool zvol isn't listed anymore...

Hopefully, this is a simple question. I have an existing 16TB volume that I use to store all of my media on. About 50% is used. I want to experiment with virtual machines. Reading through the manual, it says that I need to create a zvol for the VM. If I create a 128GiB zvol on the existing...

I have a 28TB FreeNAS 11.2 with 64GB RAM, a 256GB L2ARC and a 16-core processor. I am running FreePBX (based on CentOS) on a VM with 4GB RAM and 4 cores. I'm also running a few other VMs. I've noticed that all my VMs get slower and slower as time goes on. It gets to the point that it takes 20...

Hi, I am looking for a bit of advice or guidance. I recently installed FreeNAS-11.2 Beta and was playing around with docker containers. I was able to get the Nextcloud docker image running and stored persistent data to a mounted volume created inside rancher. Everything worked perfectly. I...

Hey, i have an SSD that all my jails and VMs run from. This is a volume with a single drive so if it ever fails i'll have a lot of work to restore. Just wondering what is the best way to clone it so i can have a backup copy if it ever goes?

Good day folks, Anybody know how/if I can create a ZVOL in the root of my POOL? I already have datasets in TANK/ZVOL, but I'd like to separate some stuff into a different ZVOL while still having access to the size of the current POOL. I'd like to add a TANK/NEW_ZVOL so I have both.. TANK/...

Hi I am new to FreeNAS. I created a RAIDZ1 total of four 3TB drives. I send my migrated my data to the new RAIDZ using zfs send receive. Can somebody explain me why i have 5.6TiB used if I only have in reality 4.1TiB of actual data? The difference between the two is 1.5TiB. What is the 1.5TiB of...

Hi guys I want to encrypt my FreeNAS box To do this I have to destroy my current volume and create new encrypted one with my disks that will erase all data on them What is the best way to transfer data from my old volume to new encrypted one? I have to move few datasets and few zvol's for my...

Does anyone know how to do this? I have a ubuntu vm running on freenas with its storage in a jail as a zvol named "ubuntu-server-nextcloud" I want to rename it as "ubuntu-server" so removing "nextcloud". Is this possible? If not I have created a new zvol named "ubuntu-server" and pointed the...

Hello, We are using some virtualised FreeNAS installations (Build FreeNAS-11.0-RELEASE (a2dc21583)) on Dell servers amd ESXi 6.5 hypervisors with enterprise SSDs on LSI 9271 IT-Mode HBAs passed-through to the FreeNAS VMs. So far they have proven very dependable. I successfully replicated a...

Hi, I have created a zvol, which is connected via iSCSI from a Mac. I setup auto-snapshots and a local replication task to a external backup drive. I have done the same procedure on a regular dataset and I received no errors. The data (non zvol replication) appears intact. However, when I...

I have a pool made-up of several datasets. Some of the datasets are zvols accessible via iSCSI. I understand that snapshots can be sent to another pool, however I do not know how to use the scheduled snapshots I am making of my "primary" pool as backups. The file names are not static (e.g...

Hi all, I have tried without luck to change the name of a zvol through the API but no luck so far. Request: https://foo.bar.tld/api/v1.0/storage/volume/(name of pool)/zvols/zvol Body: { "name": "myzvol" } Response: { "name": "zvol", "volsize": 536870912 } Is this a bug or a missing feature...

Hi all, I am trying to work with the api using documentation from http://api.freenas.org/resources/storage.html Trying to create a zvol this way: Request POST https://freenas/api/v1.0/storage/volume/tank/zvols/ HTTP/1.1 Content-Type: application/json { "name": "test2", "refer": "10M"...

I've just started to experiment with iSCSI and am looking at creating one or more iSCSI-only pools, each with a single ZVOL device extent. After reading these forums, I have some admittedly noob-ish questions: 1) With regards to the "50% rule" is it okay to create a single ZVOL that uses the...

Hello FreeNAS forums; it's been some time since I've had to post here. I guess in most cases that would be a good thing, lol. So I'm having an issue with regards to my FreeNAS SSD storage zpool that is being sent over iSCSI to my ESXi 6.5 hosts. I have a zPool of three 256gig SSDs that are...

Hey there, for spindown- and performance-reasons, I´d like to move my jails to the system dataset. I got a NAS-System consisting of a (high write endurance) SSD with 250Gb, that I planned to use as system disk and for my jails. FreeNAS is installed to this SSD and uses 1,14GB of this SSD (what...

Hi all, I have 2 freenas servers (Server1). The first one has 1 Zvol shared via iscsi to a esxi server. This zvol is replicated to the second server (Server2) via snapshots and replication tasks. It seems that the replication is working as expected, because the zvol in the replicated freenas...
