Yep it was not super clear - and to be honest I had no idea that the emulated parity 'drive' could even be formatted.

I have backups for important stuff, docuements/pictures etc, the media i'm not too fussed about losing. My bigger issue is that i have no idea what has been deleted other than a few obvious things that a docker container picked up. Will i have to download my backups and do a folder by folder comparison or is there some way to see what was wiped from the file system?

I didn’t realise that the format was also going to format disk 2, specifically the emulated parity data of disk 2. I didn’t think format would apply to anything not a real disk? My intention was to format the new drive (not emulated disk 2) the actual disk has been formatted as it is now disk 6, but data hasn’t been written to it so I may be able to recover something.

So i think i've fucked up. Basically one of my 1TB drives failed and became emulated with the above message. I had a spare 1TB plugged in ready to go. After a SMART check on this failed drive I decided to give it another crack, and wanted to rebuild onto it again as it seemed ok. I removed the assignment for the failed drive, (Disk 2). Then, somehow i ended up adding the failed drive back in a new slot (Disk 6), whilst also adding my spare 1TB back, as Drive 7. I think during this process the disks (now 6 & 7) were formatted. So the failed disk has been formatted. But the parity should still be good right? So now i have two new drives, 6 & 7, with 2 showing as 'missing contents emulated' However - there doesn't appear to actually be any contents that is emulated. Its just empty, 0 directories. and various dockers are seeing these files as deleted. At this point i have no idea how to know what exactly was on that 1TB and could be lost.

I managed to copy the config over bit by bit to the flash drive once i had a fresh copy of unraid running. I haven't copied everything - just super.dat, pools, and bits of the docker conifg. Touch wood all seems ok now. Thanks

Can this be copied to a runnign isntance remotely? Or do i need to power down and unplug the usb? Thanks (P.S. My server is in a somewhat remote position to em so i cant get there very often - thanks)

Ok i managed to get qan older version of unraid to work, with no config. At this point i'm not sure if its the newer unraid version not liking my hardware or something corrupt in my config. Safe mode etc still did not work either. Is there a way to manuually copy my config onto the running USB bit by bit? e.g. the array assignments, then the dockers?

No dice. Brand new USB, new unraid, config copied over, gets as far as /bzroot-gui... on safe mode + GUI

I've tried safe mode, no plugins etc, all the options in the boot menu. Is there anything i can try in the "Press [TAB] to edit options" menu?

A few weeks ago i woke up to my unraid being totally dead/locked. I hard rebooted the server and ever since I can't get past ../bzroot or ../bzroot-gui in the startup. Not even memtest will load. I've not changed the hardware or and firmwares, and to my knowledge i didnt update unraid either - it just stopped one day. Anyone got any ideas? Alternatively, Is there a way to put a fresh install on a USB and copy all my configuration data over, e.g. my array setup, unassigned devices, docker config etc etc

Not an unraid expert but i think your current HDD configuration could be replicated 1. Using the 'Unassigned Devices' plugin you can expose the 10TB and the 5TB on their own and then put the two 2TB in the main array with one as parity (2TB accessible) The SSD can be used as cache drive for your Win10 VM should you install one (unraid runs from a memory stick) 2. You can install Plex server directly on Unraid as a docker container. I think this container can make use of the GPU for transcoding but i'm not 100% sure 3. I dont see why not as long as you shut down cleanly and safely.

Yes i was thinking along similar lines. Or if you want a second array that doesn't have/need real-time parity. E.G a separate array for IP Camera recordings etc.

I am not planning to do this but I'm simply curious whether its theoretically possible and if anyone has tried. I searched the forum and didnt see an existing thread. Could you create a linux VM with its own IP, pass through a bunch of unassigned devices to the VM and then set up a snapraid instance on that VM? The VM would then run its own SMB service allowing you to create a second pool. Thoughts?
