Is that you Dr? How is Ms. Uumellmahaye doing these days?

Sounds like you have the file system changes well in hand. As for rearranging the disks, perhaps the easiest way to present it is with a before and after list. Current: Parity1 - SN Data1 - SN Desired end state: Parity1 - SN Parity2 - SN Data1 - SN etc. When you map out what drives you want to add vs. remove vs. move to new slots, we can give you 2 paths, safest and quickest. Do you have full backups of anything important? Mass reconfigurations like this are a really easy way to accidentally lose data. Also, when was your last parity check with zero errors, and are all the drives SMART tested good?

That's a question for the creator of the container, there is no way for Unraid to change what port the application itself listens on, it can only redirect the listening port to another if you put it on the bridge with Unraid. The application will still listen on whatever port is set up inside the container.

Why, oh why, can't there be a technical multi-lingual font that uses the slash through the number? 0̸ It would seem to me that after over 50 years of communicating electronically we would figure this kind of stuff out.

That is the best answer, however, from your statement... Makes me wonder if you know the way forward from here. The parity drive by itself has no data, it's only when it's combined with all the remaining drives can it emulate a missing disk. How are you planning to proceed?

Port mapping only applies to bridge network, make sure that's the option you are using.

When was it not? I don't use plex, but I thought from the posts I've seen over the years that has always been the case.

Yes. Yes.

The symlink solution works depending on how thoroughly the program checks for network vs. local media. YMMV on whether or not a specific app will be happy with it.

Short answer, no. Long answer, you can allocate space (vdisk) on an array drive or pool that can be seen as a physical drive to the VM, but the content won't be accessible through Unraid.

Personally I'd want to wait a week, then run another non-correcting check and see.

I'll take that bet. I think it would have slowed the writes to allow the parity to stay valid. Perhaps JorgeB could recreate this on one of his test rigs. 🙂

If you had valid parity, the added drives would have been cleared to keep parity valid before they were added, erasing any filesystem on them. I think it would be possible to have this config with parity, if you added the parity after the drives were already committed to the data slots. Various Unraid functions may be broken as a result, but it would be interesting to see. Parity doesn't care about data on the drives, so it probably would stay valid.

Do you have and know how to use a voltmeter? If the answer is yes, you should be able to test and see if the cables will work properly. If no, then either find someone who knows what they are doing to verify your setup physically in person, or don't do it. The consequences of getting it wrong is catastrophic. Trusting someone to tell you "yeah, it should work" should come with their promise to buy you replacement stuff if they are wrong. Just get a new PSU if you can't verify correct voltages before plugging in your expensive hardware.

Until parity is built and valid, disk order doesn't matter. Assign data disks to any data slot you wish.

Sure. Just make sure you don't accidentally assign a drive with data to a parity slot. You can build parity at any point, simply add a drive with nothing you need to keep to the parity slot.

That's a new one to me. Maybe @JorgeB will have some ideas. Since you don't have a parity drive, I'm thinking you can just do a new config and leave out 12 - 15, then add them to a pool so at least you will get back to a "normal" config and go from there. Whether you can split the 4 drive pool without moving data around, I don't think so, but like I said maybe JorgeB will have some options.

Depends on the system board. You have proved that the Gigabyte brix is NOT a good system to use with Unraid.

In linux, exact is critical. If you mistyped something in the newdisk path, the files would end up in RAM instead of on the disk. What EXACTLY did you put in the "olddisk" and "newdisk" part of the command? How did you determine what to put there?

Verrry nice!!!

I don't remember it NOT being a thing. I just reflexively delete one and move on.

If for some reason the USB Flash Creator tool cannot be used, or your USB flash device is not detected, it is possible to manually format and prepare a bootable USB flash device. Note: this method only works for devices 32GB and smaller. Plug the USB flash device into your Mac or PC. Format the device using the FAT32 file system. It must not be ex-FAT or NTFS. Set the ‘volume label’ to UNRAID (case-sensitive, use all caps). Go to the downloads page. to get the zip file for the release you want to use. Choose a version and download it to a temporary location on your computer (e.g. a “downloads” folder). Extract the contents of the newly downloaded ZIP file onto your USB flash device. Browse to the USB flash device to see the newly extracted contents from your Mac or PC. If you need to enable UEFI boot, rename the EFI- directory to EFI Run the make bootable script appropriate to the OS you are using:Windows XP double-click the make_bootable file. Windows 7 or later right-click the make_bootable file and select Run as Administrator. Mac double-click the file make_bootable_mac file and enter your admin password when prompted. Linux: copy make_bootable_linux file to hard drive unmount (not eject) USB drive run the following command from wherever you unpacked it to on your Linux system: sudo bash ./make_bootable_linux NOTE: during the process of running this script, the flash device may seem to disappear and reappear on your workstation a few times – this is expected behavior.

Wnat brands / models? Large physical size small capacity (16GB) USB 2.0 sticks seem to be the best for longevity in my experience.

Power down, remove the USB and check the filesystem on another PC. While you have it connected to another box, make a copy of the config folder, you may need to redo the USB stick and copy the config folder back to it.

What were the results of the df command?
