neuer_unraider

Hey, I've got a rare opportunity to host my Unraid at a friends datacenter space for basically only electricity cost, which would be a superb deal for me and finally solves the issue with having an offsite backup. I only ever used Unraid on my old desktop case/PC and it worked flawlessly since then. However, to take this opportunity, I'd have to move my Unraid to a Dell PowerEdge R730xd case provided by him. I am exactly 0 experienced in this area and from having a quick look at the tech spec, this thing doesn't offer a USB slot. Does this mean that I can't take this opportunity with Unraid? Or are there workarounds available (i. e. adding a PCIe-card which provides a USB slot or something) or being able to boot Unraid from a small SSD? The tech spec is here: https://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/Dell-PowerEdge-R730-and-R730xd-Technical-Guide-v1-7.pdf Thank you!

Hey, I am having problems with this plugin. I am using my NAS for Jellyfin mostly. I set "extra delay after array activity" to 30mins. Yet, whenever I am using Jellyfin on my Fire TV Stick, and pause the media for only 1 minute, UNRAID shuts down because of this plugin. It seems the extra delay is not recognized correctly. I also tried using "Yes, exclude Cache" for "wait for array inactivity", but it doesn't change anything. What am I doing wrong? Thanks!

I have some questions: Is /root/keyfile stored in RAM only (i. e. not written to disk)? Does UNRAID constantly scan for this file in the background? i. e. I boot the server and only 8 minutes later I am placing the keyfile there. Will it automatically decrypt/start the array then? Is there a HTTP-API available that I can call with the encryption key to start the array? Does this also somehow work with a passphrase only? Aka me sending the passphrase on-the-fly and not having a keyfile at all?

Thanks, it makes total sense. It's USB2 after all. I decided to not try it out, because the booting anyway needs to put the firmware into the RAM, so there is nothing saved skipping firmware checksum.

Hello, is there a solution to this available now? I want to sleep or shutdown my UNRAID instance using Shortcuts in iOS. For that I can either use a CURL command or a SSH command. Thanks!

Hi, I want to optimize the boot time of my UNRAID. I want to skip any bz* files/firmware verification. I know it's a risk to my data integrity, but I am willing to take that risk. This is by far the biggest chunk of startup time. How can I achieve that? Thanks!

S3 Sleep: is it possible to configure the plugin so that none of my disks in my array starts spinning? I don't need any of the disks after a wakeup and it's wasting energy every time I wake the server up. Thanks!

Das hat mich auf eine super Idee gebracht, ich mache nun was ähnliches: - Mit dem Sleep S3 Plugin von Dynamix den Tower automatisch einschlafen lassen, sobald das Array aus ist - Auf einem Raspi einen Reverse Proxy hosten, der bei einem Request einen Wake on LAN-Befehl sendet (werde ich noch einbauen) - Per iOS Shortcuts einen Wake on LAN-Befehl senden - Per Homebridge ein Apple Home Accessoir faken, sodass ich das per Siri sprachsteuern kann, welches ebenfalls ein Wake on LAN-Befehl sendet Aus dem Sleep aufwachen geht innerhalb von wenigen Sekunden und im Sleep zieht der Tower nur 3 Watt. So ist das halb-automatisiert und gut genug für den Anfang. Zusätzlich habe ich noch meine CPU undervolted und 2 von 4 RAM-Riegeln entfernt (die ich eh nicht brauche). Und powertop läuft nun auch nach dem Boot. Ich komme somit nun im Array-aus-Rest-an-Idle auf 32 Watt. Danke für Eure Ideen!

@doron can you add a flag to not replace the keyfile but rather add another one? I'd like to use a keyfile during normal operation but I am paranoid and would like to have an additional ultra-secure passphrase as a backup that I will remember that I definitely don't want to enter in because it takes a long time manually doing so.

Ich möchte gerne meine unRAID-Installation etwas umbauen und das Teil nur noch als Datengrab nutzen. Grund sind die horrenden Strompreise und eigentlich brauche ich das NAS nur 10min pro Tag, um da Backups draufzuspielen. Vielleicht mal für 1,5h, um einen Film über Jellyfin anzugucken. Mir kam also die Idee, das NAS quasi immer aus zu haben und nur entweder zu bestimmten Backup-Zeiten zu starten oder on-demand automatisch, wenn jemand über Jellyfin darauf zugreifen möchte (ich dachte da an Wake on LAN oder ähnliches). Hat damit jemand Erfahrung bzw. ist das umsetzbar, ohne dass ich manuell booten muss? Die Lösung zur automatischen Passphrase-Eingabe beim Boot habe ich schon gefunden. Mir geht es eher um die Praktikabilität der Idee. Meine Hardware ist nämlich uralt (2013, Intel i5 3570K / AsRock Extreme 4) und dementsprechend zieht das NAS auch viel Strom. Die paar kleinen Docker-Services hätte ich dann auf einen Raspi 4 gepackt, welches dann per SMB/NFS auf das Datengrab zugreift. Am unRAID hängen 2x NVMe als Cache sowie 4 HDDs. Danke für Eure Erfahrungen!

Thank you, that made it!

@Kilrah I am not hijacking anything, it's even officially documented here: https://wiki.unraid.net/Manual/Security#Custom_Certificates

This is the path it shows in the settings UI. I just replace that file with my custom certificate (it has nothing todo with Unraid.net or whatever server they offer), but nothing happens. Unraid only picks it up when I press "Provision". So I assume that I need to press that button. If there's a better way, please tell me

Hey, I'm providing a custom SSL certificate to Unraid and update it with a shellscript. Still, I need to click the "Provision" button under "Settings -> Management Access" manually: How can I invoke the functionality of that button from my shellscript that's running on the server?

Hey, some days ago I encountered weird system behaviour and could grab this out of `dmesg` before the system went unrensponsive. The call trace looks like it has something to do with swap. But after reseraching this for a while it seems that Unraid doesn't use a swap partition or swap file by default. Since I never configured a swap on Unraid as well, I am very confused about this panic and don't know if it even has to do with the swap that I know from classic Linux. No data seems to be lost on my disks or the boot stick. Parity check was successful. I'm using btrfs with 2 NVMes in a cache, 1 parity HDD and 3 additional HDDs. Is this some sort of case where cosmic radiation caused a bit flip (I'm not using ECC RAM) and I shouldn't worry about this or might there be a deeper root cause which I should investigate?
