We hope to see it grow in coverage and detail, beyond the current limited set of questions and answers, and the common use of links to answers rather than a full answer. The process of adding questions and answers involves first adding a question with a link to a relevant forum thread, then hoping for someone to take the time to add a full writeup. It is nearly entirely written by users of unRAID. It is not an official document written by Lime-technology LLC. With apologies, this page is under construction, and the included info is still rather meager and dated, but with time and your help, it will improve.
Once a disk is disabled, its contents may be invalid, because there may have been uncompleted writes. All further write requests will be similarly simulated.
It is very important to determine WHY the disk was disabled, because very often it is not the fault of the drive.
More often than not, we find that there is an interface issue to the drive, such as a bad SATA cable very common or bad or loose SATA cable connectors, or power issues such as bad or loose power cable or its connectors, bad power cable splitter, too many drives on the same 12v power rail, or bad power supply. Some times, it is just a disk controller that went offline, making it impossible to access the drive.
The first step then is to examine both the syslog to see what kind of errors are being reported, and the SMART report for the drive, to check its status and errors. Please see the Troubleshooting page for more information and instructions. For advanced users, see the The Analysis of Drive Issues page for examples of drive and interface error messages.
If you determine that the drive is bad, then it needs to be replaced, see "How do I replace a hard disk? If the drive was fine, and you either found and corrected an interface issue, or could not find anything wrong, then the disabled drive still needs to be re-enabled. There are 2 ways to do it, and the choice depends on whether you have made changes to this drive after it was disabled.
It was taken out of service and disabled because a "write" to it failed. It is guaranteed to not have the correct current contents. If you do not care about losing anything recently written to the drive, or can live with a file that was partially written with the subsequent "write" failed, or file-system corruption because the file structures were not written properly, then read the Trust My Array procedure, and see if your array qualifies for it.
If so, then the Trust My Array procedure is perfect for quickly returning your array to all green. Let the ensuing parity check complete. You have been warned. It is almost never the correct action to take.
If used, you should then check the filesystem for corruption and then get parity in sync with a parity check. If however you have made changes to the drive that you do not want to lose, or do not want to risk file-system corruption, then you will need to rebuild the drive in-place, with the following procedure very similar to replacing a failed drive.
If you are trying to recover files and folders from a drive with a Reiser file system that appears to be corrupted, please read each of the following articles and threads:. If the Reiser file system is fine, but you want to access its files outside of your unRAID array, here are 6 ways to do it:.
UnRAID 6/Getting Started
There are no known undelete tools for the Reiser file system, which the unRAID system uses for each data drive. However, there are techniques that can be used to recover files. A disk can fail to be mounted and as a result, show up as "unformatted" when ANY of the following occur:.
As of unRAID v4. This method involves adding cat commands to the go script. Ignore the output of the cat command.Official Documentation Contents List. Click on the Main tab and select the devices to assign to slots for parity, data, and cache disks. Assigning devices to Unraid is easy! Just remember these guidelines:. NOTE: Your array will not start if you assign or attach more devices than your license key allows.
Normally following system boot up the array complete set of disks is automatically started brought on-line and exported as a set of shares. But if there's been a change in disk configuration, such as a new disk added, the array is left stopped so that you can confirm the configuration is correct.
This means that any time you have made a disk configuration change you must log into the webGui and manually start the array. When you wish to make changes to disks in your array, you will need to stop the array to do this. To start or stop the array, perform the following steps:. If the array can't be started, it may be for one of a few reasons which will be reported under the Array Operation section:.
If you have a single parity disk, you can only have up to one disk missing and still start the array, as parity will then help simulate the contents of the missing disk until you can replace it. This rule only applies prior to starting the array. Once the array is started, you are free to attach additional storage devices and make use of them such as USB flash devices for assignment to virtual machines. In Unraid Server OS 6, the attached storage device limits are as follows:.
Those limits are imposed by the software, not the license policy. A valid registration key is required in order to start the array. To purchase or get a trial key, perform the following steps:. If the word "expired" is visible at the top left of the webGui, this means your trial key has expired. Visit the registration cage to request either an extension to your trial or purchase a valid registration key.
If your server is connected to the Internet and your trial hasn't expired yet, it is also possible that your USB flash device contains a GUID that is prohibited from registering for a key. This could be because the GUID is not truly unique to your device or has already been registered by another user. If a USB flash device is listed as blacklisted, this is a permanent state and you will need to seek an alternative device to use for your Unraid Server OS installation.
This message will only occur if you are using a Trial licence. If you are using a paid-for licence then the array can be started without the need to contact the Unraid licence server. If your server is unable to contact our key server to validate your Trial license, you will not be able to start the array. The server will attempt to validate upon first boot with a timeout of 30 sec.Unraid OS allows sophisticated media aficionados, gamers, and other intensive data-users to have ultimate control over their data, media, applications, and desktops, using just about any combination of hardware.

From the Forum Unraid OS version 6. Home Gadget Geeks Unraid Show. Unraid Monthly Newsletter. Unraid OS 6.By linuxserver. Thank you soo much. I already posted a few days ago regarding setting up letsencrypt for nextcloud and got from no access at all to remote access only, which i am very happy about. Remote access works perfectly with duckdns but i still can't get local access and that is what i am trying to fix.
I have port forwarding rules setup and as remote access works, i tend to think that they are not the problem. Here are the results of nslookup and tracert from a computer within the same network behind pfsense as the unraid server on which letsencrypt and nextcloud are running:. My interpretation is that the dns override works as it is correctly resolved with the external internet ip.
Is that correct? Or should a local dns lookup response be the local ip adress? The fact that the dns seems to work leads me to believe that the problem lies with my configuration of letsencrypt possibly nextcloud?
Here is the result of a tracert showing the connection timing out:. I am quite a networking newbie. I have tried to read and inform myself as much as i could, but i can't seem to figure this out. Any help would be greatly appreciated. Meaning you are using a public IP range for a private addressing. CHBMB can you help here? Sent from my Pixel 2 XL using Tapatalk.
Lynxphp you also created an alias for your nextcloud. Let's do this. Why don't you focus on getting your certificates working first, and then you play with adding aliases. Since you have no control over duckdns I'm not sure you can do nextcloud. Also check this forum, that has been talked before in here.
Also, gacpac whilst your enthusiasm is admirable, I'm not certain you understand this stuff as well as you think you do, and no disrespect, you're sometimes confusing the issue even more.
Unleash Your Hardware
Lynxphp Try adding this in pfsense in the custom options of DNS resolver. And as we've told Lynxphp previously, the issue is probably hairpin NAT.
I do like to help, but that's why I said correct me if I'm wrong. Also sorry If I pinged you, to jump in on this, but you don't have to reply if you are busy.Official Documentation Contents List. In this guide we will be covering how to prepare your flash device, boot the system, and configure your first array. The entire process should take less than 15 minutes.
Installing Nextcloud On Unraid with LetsEncrypt Reverse Proxy on nextcloud.server.com
Before we begin, you should have your server assembled, connected via power and Ethernet, and you should have a monitor and keyboard attached for the initial configuration to be ready to alter configuration settings in your BIOS. For full hardware requirements, visit our product page.
Using this program, you can easily convert almost any USB flash device into an Unraid boot device. In addition, the flash creator will give you the option to toggle some advanced settings such as loading a beta release, renaming your server hostname, setting a static IP address for your server pre-boot, and even toggling support for UEFI booting.
Configuring your motherboard BIOS as well as your storage controller correctly is an important step to ensuring a solid experience using Unraid. The basic guidelines are as follows:. If you still are unable to boot the OS, please post a message in our general support forum. NOTE: Many motherboards support only up 12 hard drives for purposes of boot selection. To avoid this, if possible set up your bios so that the Flash is treated as a removable device. Unraid's management interface the webGui is incompatible with most ad-blocker solutions.
It is for this reason that we strongly suggest that users leveraging an ad-blocker in their browser first add the Unraid server to the ad-blocker whitelist to ensure the ad-blocker doesn't affect the webGui. Upon connecting to the Unraid webGui for the first time, you should be taken to the Registration page.
From here, you can register and install either a trial or paid license key. After installing a registration key, you are ready to begin assigning devices for Unraid to manage. Click on the Main tab from the Unraid webGui and follow these guidelines when assigning disks:. NOTE: Your array will not start if you assign or attach more devices than your license key allows.
Once you have all your devices assigned, you can click the Start button under Array Operation. This will mount your devices and start the array. New devices added to disk or cache device slots will appear as 'Unformatted' and will be unusable for storing files until you format them. Even before the devices are formatted, a parity sync will be performing in the background to initialize the protection of the array.
Until the sync is completed, the array will operate but in an unprotected state. It is recommended to wait until the initial parity sync completes before adding data to the array. In order to perform one of these operations, visit the Main tab and scroll down to the section titled Array Operation and click on the button appropriate to the operation you wish to carry out.By bonienlDecember 9, in General Support.
The passphrase or keyfile which is used to unlock encryption is not permanently stored on the system itself, this means that upon a system start one has to re-enter the passphrase or re-select the keyfile.
Until then the array can not start and the GUI will report a "missing key". But what if we want to auto-start the array and not keep a local copy on the system itself?
In my case I am using an arbitrary. Of course the remote share must be accessible when the system starts and surely this approach can be cracked, but it is definitely safer than just keeping a local copy of the keyfile on the unRAID server itself.
Remember that once the array is started, the local keyfile may be deleted if you really don't want to keep the key while the system is operational. What a great suggestion. I think I am going to try this on my next build. It can be configured to be a headless samba server and have SSH capability.
Power consumption is under a watt at idle. A small variation if you want the key to be not locally present on the system when operational, the key is only needed during startup of the array. You can start and stop the array as usual, and the key will be automatically fetched each time, provided that the remote service is up and running.
Thanks for the info! We will call these servers U1 and U2. Both have a static IP and are plugged into a switch. U2 has a share named U1-key and U1 has a share named U2-key. Both have corresponding secure accounts. If both are on and I reboot U1, upon boot it reaches out to U2 and gets its key.
If both are on and I reboot U2, it reaches out to U1 and gets its key. If both are off, I boot both and manually start the array on U2 much faster boot time and by the time U1 is up, it pulls its key from U2. Seems to be working well for me so far. Best of all, with this setup, if both are off as would happen if someone walked off with my server rackboth keys are on encrypted drives, so the neither of them should be able to be booted without my key.
Very thoughtful solution, but I am wondering if there is a security flaw.This page describes how to replace an unRAID array data drive. Why would you want to do that? Any number of reasons. Jump to: navigationsearch. The Preclearing is not strictly necessary, as replacement drives don't have to be cleared, they are going to be completely overwritten. But Preclearing new drives one to three times provides a thorough test of the drive, eliminates 'infant mortality' failures. It's always good to have a prepared and tested replacement drive already on hand!
If your replacement drive is larger than the parity drive, then proceed to The parity swap procedure. If too large, unRAID has a special two-step 'Parity Swap' procedure often called the 'swap-disable' that will use a larger than parity drive to first upgrade the parity drive then replace the old drive with the old parity drive.
If you are here because you have a disabled drive, and you have already checked the syslog and SMART report or got instruction from the unRAID forumsand are SURE that the drive is good, then you can use the procedures below to rebuild it onto itself below, consider the 'old drive' to be the 'new drive'.
If you are running v5 or v6 of unRAID, then go back to the previous section. Stop the array Power down Replace hard drive with new drive. Turn on Replaced drive appears with blue dot Tick the "I'm sure" checkbox, and press "Start will bring the array on-line, start Data-Rebuild, and then expand the file system.
