Make sure you purchase CMR drives and not SMR drives. Personally I recommend fewer larger drives than more smaller drives. These drives have non-insignificant idle power costs so you will be saving a decent amount of money every year going with the larger drives. Also you do have a limit of how many hard drive bays you have so using larger hard drives makes the most of each bay if you ever wanted to expand. I would go with three of the largest hard drives that financially and practically make sense for you. This is because you need a minimum of three drives in a pool already if you ever want to expand a pool in HexOS

As a way to test-drive the system, forcing provisioning of storage (which means wiping data) is scary as hell. I completely understand the need for an active pool to assign for app (docker) deployment. Thankfully, disconnecting the drives during provisioning, the step does not block. Pros: allow test-driving system before committing allow troubleshooting the setup process without loss of data allow advanced users to deal with data recovery Related posts that this might help with: https://hub.hexos.com/topic/1991-ability-to-choose-if-you-want-to-wipe-storage-or-not/ https://hub.hexos.com/topic/1244-easy-migration-from-old-hdds-to-new-hdds-ssds/ https://hub.hexos.com/topic/345-ability-to-import-existing-zfs-pool/ https://hub.hexos.com/topic/192-migration-from-existing-truenas-server/ https://hub.hexos.com/topic/1244-easy-migration-from-old-hdds-to-new-hdds-ssds/ https://hub.hexos.com/topic/1368-future-upgrades/

Now, I’m on my way to earning the moniker ”SFF ninja” given to me by @Dylan in another post. Not there yet but slowly going in that direction.

It's my understanding you set it up once, which will auto setup for you in Z1, but then (before adding data), you delete that pool and then re-setup in Z2 (RAID 6 if you will). Hope that helps.

Hey, you can use this raidz calculator, set number of disk groups to 1 and fill in all other numbers. If yoh have 3 or more disks hexos will create a raidz1, so you set this as raidz type and you get your usable storage in TB. (Don't forget to convert this to TiB) https://www.raidz-calculator.com/

I'm using a RaidZ2 without any issues, but I'm also not using any of the apps, since I'm running an Ubuntu VM with docker for all my apps. I didn't follow all the discussions but it seems that destroying the first pool created results in apps become unusable until some paths/settings are fixed in TrueNas, but don't quote me on that, maybe someone else has more information about this. To add to @Mobius explanations about the Vdevs: Once you loose all the drives from 1 vdev you loose everything. Meaning with 3x2 drive vdevs you can only loose 1 drive per vdev (but 3 drives in total if they are all from different vdevs) and with 2x3 drive vdevs you can loose 2 drives per vdev without loosing any data. @L-Pif you have 10 gbit/s networking, you might want to look into adding an nvme cache drive as an L2ARC. ARC is a read only cache, which is keeping the files which you might need next in a cache in memory for quick access. You can extend this with an L2ARC cache which, stores additional files on a dedicated drive. If this drive is an SSD it's gonna ready and serve those files significantly faster then if Hexos needed to read them from the slow HDDs. This might make sense in your case if you have 10gbit/s networking, everything below and the speed benefits are likely to be marginal at best. And no there is no write cache in Hexos only a read cache. 🙂

I need my pool to be RAIDZ2, but RAIDZ1 seems to be the only option in HexOS... Someone suggested setting RAIDZ2 in TrueNas; can this break anything in HexOS, it's safe? I need really fast read/write speed and redundancy because I'm video editing directly on my NAS. I'm even considering RAIDZ3. Can someone tell me the best way to go about this? At the moment, I only populated 6x 20TB SAS drives in a RAIDZ1 pool.

the update notification is a known bug. essentially there is an update for the underlying truenas system. at this time the hexos team has stated that you should not update and ignore the notification.

We want a NAS system built from TrueNas. File manager support directly through the GUI. This means that we would be able to move and upload files through a graphical interface through a browser. Folders in Hex only have the smb function and cannot be directly opened and handled with the contents.

If you start with two drives you can't nicely expand the pool via HexOS, but can probably drop and recreate the pool with the third drive later on. Not sure if/how data would be retained

Installed Hex a couple of hours ago. The main thing feedback that I have is that the install window for any app is placed at the top the of the app page and not locked to the local top of the screen or next to the app. Is there a way to change that? When I am looking at the apps I possibly want to install I would like to read the top description before I install.

Here is how I got GPU passthru to work. First I logged into the trunas UI and went to System -> Shell Once in the shell I ran a command to find my gpu slot and uuid truenas_admin@YOUR-NAS[~]$ midclt call app.gpu_choices | jq { "PCI_SLOT_VALUE": { "vendor": "NVIDIA", "description": "NVIDIA GeForce GTX 960", "vendor_specific_config": { "uuid": "GPU_UUID" }, "pci_slot": "PCI_SLOT_VALUE" } } Then I ran a command to set those values in the plex app truenas_admin@YOUR-NAS[~]$ midclt call -job app.update plex '{"values": {"resources": {"gpus": {"use_all_gpus": false, "nvidia_gpu_selection": {"PCI_SLOT_VALUE": {"use_gpu": true, "uuid": "GPU_UUID"}}}}}}' SORRY I DID NOT CAPTURE THE OUTPUT

Someone copy and pasted from an AI ;-). UPS support is definitely something we want to do, but will likely come after the 1.0 release.
