Got the same error. I did several disconnections and connections to get it back to normal state.

A) You already can set your server with ZFS plugin if using ZFS is what you're intending to.

Looking forward with an certain enthusiasm. Thanks for your work. 💖

I was thinking the same too (no joke). 😁

As a non-conventional channel delivery, Don't expect beta releases to guarantee any upgrade to RC. This is an internal Limetech testing process. Final beta that shall be packaged as RC then is meant and coded to be smoothly upgradeable from official previous releases. That's the purposes from beta.

Sounds like a reason to worry. Run a full smart test.

Check the SMART info relative to the disk. If everything is alright, run "zpool clear" and another scrub on the "citadel" pool. If no more error occurs, continue to use your pool safely.

Concerning this troubleshoot, you can run the docker image within a ZVOL on a ZFS volume. It authorizes to create a XFS, BTRFS or any Filesystem "partition", inside ZFS. Notice the quotes because it's not at partition at all. My own server uses this to fully run with ZFS and not dedicate a full drive or partition to the docker files.

Indeed, this is not an official thread. Just sharing our enthusiasm and questions about what might happen. And this "morse session" seemly has been more overflowing than expected. However, if some reactions were "childish", others were "grumpy". It doesn't make sense to me feeling harassed or annoyed at this point. I clearly don't spend my whole time on this forum and didn't witness such a "craziness", in a certain way, until now. So I am probably less impacted than others.

Good to know. I've no HDD on my setup, so I wasn't aware that the GUI has this functionnality... 😅

Sure, powertop or hdparm can set HDD spinning speed.

Your concern is kind. Thanks however

ARC is also included with ZFS single drive volumes (or vdev). It caches each file read in RAM and the most used files used. Some more properties proper to ZFS can also be managed.

Euhhhhh... You can already use ZFS in Unraid with no GUI, instead of leaving the dust on your server : Support Forum

I doubt as the PR is still opened on the github. But indeed, the operation is already available for mirrored vdev. Concerning ZFS support in Unraid, it's "coming" in Unraid 6.12

In this expected configuration, the SQL docker must run on its own storage datastore, independent of the application pool storage running grace to your database container. Because the expected failure is then your SQL storage, what about the application storage? You'll be only able then to restore your system in one situation. Not ideal but that's a beginning. Whatever, an HA is litteraly a copy from your whole system on several servers. So your scenario is still not ideal for full HA.

The only good DIY alternative would be to proceed ZFS replications and using Mikrotik router (cheaper and customizable) to proceed "heartbeat" from your VM with ping or from your host each minute. In case of failure, of VM or container answer, the Mikrotik can proceed an SSH session to boot the sibling VM/container on the backup server, but trafic also need to be manage on the network side. So another mess to script also according to your need.

Don't expect to do HA with Unraid, it's not expected to do so. ESXi with the vCenter is the basic one system to do so. You can proceed to replication each hour with a third server (better than a VM) hosting Veeam. The vCenter Replication can do so each minute and give more automatic actions in case of emergency. Some other solution, still with vCenter, is Datacore, but as all others solutions I quoted, you've to pay and you can't crack this solution, whatever, it works with an ideal HA server and its network. You can find ESXi and vCenter keys on github dedicated for labs. Host Unraid VM on it and proceed to replication according to the solution you're using. But if you're a rookie, I stronlgy do not recommand to do so. It's easier to manage backup instead of setting up and managing an HA solution. Load Balancing and Failover need to be also managed from your router if you're expecting traffic from WAN to work.

0 Deep in my cave, is stored a silent server, only its fans wheels can be heard like a whisper. This server is a SuperMicro 1018GR-T. This 1U server is connected from the deepest places of my home to the brightest places of the internet by Mikrotik RB4011-GS+ directly connected to my French ISP (Orange) GPON. up. Once the server is opened, most of these secrets shows Its components are brighter than the shade around us. First of all, the heart of the beast : a Micron e230 USB DOM. This tiny card of 4GB/Go is equipped with ECC components that shall assure that Unraid doesn’t suffer from corrupted file due to magnetic interferences.. How can it be reached in such as dark place where no light seems to descends ? A second vital element then shows up : an SSD-DM06 from SuperMicro, this special SATA port is able to give it the power to run. This cards is dedicated to store the Unraid’s logs. Not so far can be seen 8 sticks of RAM from Micron. It appears that the server is equipped with 128GB/Go ECC RAM from Micron. Enough to run one Chrome tab with a bright sun if this last one would come down here. The machine is equipped with 6 SATA SSD from Kingston. With a capacity of 11.52TB, this server could store a quarter of Star Citizen at max SATAIII speed 600MB/Mo’s. With its Power Loss Protection (PLP), the data cached in its own RAM can safely be written to the NAND in case of power outage. Those 6 drives are connected to a AOC-S3108L-H8iR from SuperMicro. As the SATA SSD saturates the DMI which needs to vehiculate ethernet packets too, the motherboard needs it to not suffocate. Finally, a green card can catch our eye. This RTX Quadro 4000 is more than enough to run Minecraft Java. This less blinky card show up. The dark plate was hiding a silver one on the otherside. It seems to hide something in it… The card dissected, some jewels can catch our attention. An Optane P4801x ! This memory’s so fast, that no RAM are required to access the data in its cells quickly. PLP is still present as some capacitors appears on its body. It let the controller the time to run the last received instructions and store it in the 100GB/Go storage. Some more conventional flash cells are also on the Hyper M.2 Asus card. 2 Micron 7400 Pro with PLP are there as long as the 110mm Optane stick’s length. A little 80mm stick remains, a Crucial P5 with 2TB/To of storage, as much as the Micron sticks. Finally, a V7 1500VA UPS is calmly sitting in the floor of this rack to assure the best to run endlessly, even in case of power outage for 40 minutes

ZFS raidz expansion is not available yet. You must destroy and create a pool with each disk. Copy your data to an external USB drive temporarily to create your new zpool.
