Absolutely. I just wanted to clarify what you mean by “good backups" in that case. Thank you Jorge!

Thanks again. Last question: what do you mean by "good backups"? Backups of the NAS content, in case of drive failure and raidz1 cannot solve it, cause raidz2 or more would have been needed?
-
Thanks @JorgeB - drives are 16TB each (Seagate Ironwolf Pro). Would you rather add drives gradually as more space is needed, or go straight to a larger RAIDZ2 setup? I’ve read that RAIDZ expansion puts quite a bit of IO stress on all drives, so I’m wondering whether doing a bigger migration upfront might actually be better for drive-health. Or is the additional IO load during RAIDZ expansion basically negligible in terms of overall drive health, if it only happens every 3 months or so? For some additional context: with my current storage growth, adding just a single drive would probably buy me around 3 more months before needing another expansion. Adding 4-6 drives instead would likely give me much more breathing room and possibly avoid another expansion entirely for the next few years.

Hi all, Currently running a 4x16TB ZFS RAIDZ1 pool on a machine that could handle much more. I’m thinking about expanding storage. My original plan was to add 1-4 drives and eventually move to RAIDZ2 / dual parity. From what I understand, you can grow an existing RAIDZ1, but cannot later convert it into RAIDZ2. Is that correct? So what would you consider the smarter approach, especially now in light of the insane prices for storage? 1) Expand the existing RAIDZ1 gradually? Like 1 drive at a time. (if so, how many drives would you risk to keep in RAIDZ1?) 2) Rebuild/migrate into a fresh RAIDZ2 pool? (If so, where do you park your stuff during migration? I could temporary expand a cloud storage. Is that already the answer to my question? ;) ) 3) Or any other idea? Thanks for any advice. :) And sorry if this has been asked a million times before.

Thanks! I should be good then. Does ECC require config in Unraid or is proper setup in BIOS enough?

Hi all, I’m moving my system from a Ugreen NAS to a custom build. Both are Intel, different CPU and RAM though. Drives stay the same. Not much other hardware to pass through. Yes, I have watched Spaceinvader’s video about hw migration. Q: I wonder whether ZFS pools make a difference in the process? Does Unraid require config for ECC? That is also new for me on the new system. And is there anything else to keep in mind except the obvious backup? Thanks!

I will test without for now first, and see if that behavior shows again. Did you spot anything suspicious in the diagnostics? Any chance you could take a glance at it? :) @MAM59 hot glue lol

Hi everyone, my Unraid NAS (Ugreen 4-bay) has been crashing more often. I noticed, that during boot the Unraid stick does not get recognized by BIOS, so it loads into Ugreen OS directly instead. The Unraid USB stick is connected to a right-angled usb adapter. Without the adapter it works reliably, with it only sometimes. Stick: Transcend USB 2.0 32GB (2 years old), adapter was used for 6 months now without causing issues (afaik). Can a right-angle USB adapter just fail from one day to the next, or is it more likely the USB stick starting to die? Any tips on how to properly diagnose which component is failing would be very helpful. Thanks! edit: diagnostics from after last succesful reboot attached mercury-diagnostics-20250926-0840.zip

Hi, downloading diagnostic fails / time-outs at the step shown in screenshot. Marked it as urgent as it prevents me troubleshooting regarding another urgent issue. Feel free to re-categorize. Tested to download on Brave/Safari/Firefox on MacOS, all latest versions to date. Thanks downlod-syslog-log.txt

I keep getting these false error mesages about my attached UPS named 'mercury', despite batteries should be fine and there were no power outage or any other power-related incident at all. These errors started to appear about 2-3 weeks after installing the UPS. Before that: no error messages. I tested power cut-offs twice, batteries were running fine during the calculated up-time and the controlled shut-down worked as intended, too. The UPS unit incl. batteries is new. I have the same model on a proxmox cluster which works fine, too and does not output any errors, so I am assuming a bug on Unraid-end. Please help to troubleshoot / or at least confirm if its a bug! This is concerning. (I marked this as urgent as these errors appear nearly anytime I log into the Unraid gui and make me worry if this is a false emergency or an actual issue with the UPS, which I absolutely require to work reliable. Feel free to re-categorize, of course.) Thanks! btw. while writing this post I realized, that downloading diagnostics fails. Don`t know what`s up. This always worked. Going to open a seperate thread for that one. Edit: here. Meanwhile, please find latest syslog atached. As you can see, lots of UPS related errors. syslog.txt

Hi, what docker registry is Unraid using? Whatsupdocker running on another host is complaining: "No Registry Provider found" for all containers installed through the Unraid app store. (Yes, I am passing the Unraid Docker API through) Thanks!

Hi there. Before I dive too deep into this: what are your thoughts about feasibility of this idea? Automatically de-crypt a whole zfs-pool through a go-script that checks if a YubiKey usb key is present. The steps I had in mind roughly: Create a LUKS key file and encrypt it with GPG using a public key whose private key resides on the YubiKey Store the GPG-encrypted file on Unraid flash drive Use a startup script to copy and decrypt key requiring the YubiKey to be present Delete decrypted key copy so that the pool remains unlocked, but cannot be re-unlocked if the YubiKey isn’t available First of all, what do you think? Bananas? If not, how would you implement the Unraid specific part (step 3)? I assume doing this for a whole zfs pool a script in /boot/config/go must be required, so that it happens before the array starts? Any other thoughts or recommendations?

Thanks @JorgeB

There you go @JorgeB <edit: deleted after solution>
