I’m having the same issue. I went to update my os and Im getting the flash drive is now corrupt. Did you get it working?

understood. Thats what im working on now. I already lost my entire plex database once. I just restored it and it happened again. Also the cache SSD has been running really hot, like 51*C. Im not sure if thats adding to the issue as well. I have my server with the cover off while im testing things so maybe the airflow isnt enough to cool it now.

Are you saying i need to backup the entire pool or just backup the cache drive (which I am currently doing now)? My pool is 45tb and i do not have the capacity to back it up. I was reading that I need to do a mem test and my ram may be bad. Im doing to do that when i get home today.

Please also see the diagnostics attached. diagnostics-20210819-0828.zip

I have a problem the other day where my cache drive suddenly was unmountable after a reboot. I have not idea why this happened. The drive doesnt state any errors ion the smart check. I currently have the system still running but the cache drive is read only so i know once i reboot the machine i will lose the drive again. I have pulled the log of the disk and pasted it into pastebin. Can someone please check it out and see if they have any idea what is going on. The cache drive already had to be reformatted once and I lost all my appdata info (i.e. plex, sync, sickrage) and i just redid everything today. https://pastebin.com/rD6Crnah

nothing running in open files...docker wont start again and cache drive is filled. I think starting from scratch will be much easier as i didnt fully has the system set up anyways. I was just focusing on transfering all my media. Is there a way to just start from scratch but keep my media and shares?

following up. I was able to get my VM services and docker services to load. I had to redo all the dockers. I am now having an issue were i cant unmount the arrey and my cache disk is filling up and not offloading. As of right now I am thinking about starting from scratch with the unraid setup. Is there a way to start from scratch with unraid but still keep all of my data intact on the array? i.e. the media i already transferred but as a new unraid setup so i can reconfigure everything?

Copy! Thank you very much for your assistance! I really appreciate it! I will follow up with the final result once I get home.

Thank you very much JorgeB! One last question. What should I use to transfer the files? I was transferring all of my media using my windows VM and the share folders. Im not very proficient in linux/command line but if you point me in the right direction I can definitely figure it out.

Update. I recovered all the files. I need to figure out how to get the follwing files in the correct places: docker.img libvirt.img virtio-win-0.1.190-1.iso Can anyone assist? Once i put disk on back in the array and start the array, where and how to i put those files back?

The docker tab is available but the VM tab give me an error since I have rebooted the machine. Please see the attached diagnostics zip. any assistance would be awesome. Thanks for your help! Update: I am currently recovering all of the data. It was all recoverable it seems. I can worry about restoring the media later on but I just want to get the core files back into unraid so I can run my VM etc... diagnostics-20210609-0513.zip

Understood.... So now *if* i am able to recover the files how would I go about repopulating those files back on to the array? part of what I lost was my VM which is what I was using to move files into the array/shares. I cant do that since the whole VM is now lost. I need to know how to manually move the files I recover back into the array like nothing ever happened. i.e. i need to get my VM back to where it has to be...the docker files where they need to be to start the VM etc..

This is also my log from yesterday and today. This is when i began messing around with the file system. syslog 6.7 amd 6.8.txt

First off, everyone on this forum is amazing. I was able to ALMOST move from my main windows server to Unraid. I have the server set up, I created a windows server VM, and various other plug in etc. I have slowly been adding more hard drives to the array while I transfer all my files off of my old server. When i first started unraid up I began with a 500gb hard drive just to get familiar to the system and get everything going. Since then ive added about 6 more hard drives. Today i got the bright idea that I wanted to remove the 500gb hd from the system. I do not have a parity disk yet because I am still working on transferring over about 40tb of media. See below for the (mis)steps i took and I would like anyone's advice to help fix the situation. I used midnight commander to move all of the files off of the 500gb hd to the cache drive. I set all of the shares to only use disks 2 - 6 and not to write any other data onto disk 1 which is the 500gb hd I then deleted everything on the 500gb HD I *THOUGHT* the cache drive would move everything over to the other hard drives as I set the shares to only allow disks 2 -6 while excluding disk 1 The cache disk did not do what I thought it would do so I decided to try to use MC to then move ALL the files from the cache over to the /mnt/usr folder thinking it would just repopulate the files from the 500gb hd. This didnt work and while it said it moved all the files over from the cache drive it didnt. it appears to have just put place holders but didnt actually write the data. Now the cache drive is empty, the 500gb drive has all the files deleted from it, and my VMs and plugins arent working (obviously because I basically deleted everything from the beginning of the unraid install when I was only using the 500gb hd.) I understand i went in way over my head without doing the proper research first...I guess thats just the learning curve I took. My question is.... Can I pull the 500gb hd from unraid, install it in my windows PC, use "recovery explorer standard" to recover all of the files (https://www.sysdevlabs.com/product.php?id=rxs6#specification ), put the 500gb hd back into the unraid cluster, install the temp hard drive with the recovered files as an unassigned device, and recopy the recovered files back to the 500gb hard drive? I should be able to recover the files from the 500gb as i only did a delete and before i deleted anything I set unraid to not write any files to the 500gb hd. If I can do this, how would I correctly move the recovered files from the temp hard drive to the original 500gb hd without further screwing everything up.

I am moving into a new house in a couple months and I want to move everything over to Unraid. I plan to copy the above programs exactly as well as benefit from some other Unraid features that I havent researched yet. The new house will have about 16 cameras instead of the current 4 that are on my old house. I will have a server 34U server rack in the garage to install all of my networking equipment. this is the rack im planning on getting: https://sysracks.com/catalog/sysracks-srf-900g/32u-35-depth-24-x35-x66-19-it-telecom-cabinet-sysracks-srf-32-6-9-g/ Right now I have the following configuration for my media server: Fractal Design Define R5 case Intel Core i7-4790K 4.0GHz LGA 1150 CORSAIR RM Series RM650 650W GIGABYTE GA-Z97X-UD3H-BK G.SKILL Ripjaws X Series 16GB 256 SSD SATA OS harddrive LSI SAS 9201-16e NetApp DS4246 running about 10 mixed size hard drives (60TB total) The computer is currently running Win10 and NOT Unraid yet. The only software I use at this point is Plex Media server, drivepool, Sickrage, couch potato, Sync, and Blue iris. I would like to setup the software as follows: Plex docker Sickrage docker? if available Couch potato docker? if available Sync Docker? if available (if Sickrage, couch potato and sync need to be run on windows, Ill run 1 VM of all of this) blue iris docker Im looking at purchasing something like this: https://www.ebay.com/itm/FREENAS-Storage-Server-SAS3-12Gb-s-4U-36-LFF-Bay-X10DRH-C-Xeon-12-Core-CPU-Rail/143961202284?hash=item2184c19e6c:g:cMsAAOSwCpxfqXnb or https://www.ebay.com/itm/SAS3-12Gb-s-UNRAID-Supermicro-Server-2U-12-Bay-LFF-Xeon-E5-2620-V3-12-Core-64GB/133448708195?hash=item1f1229b063:g:q-sAAOSw7t9e4qt~ What is everyones thought on the above setup. I would like to get a rack configured desktop so that I can cleanly install it in the 34U rack. I may get a GPU for the Blue iris setup but im not 100% sure ill need it until I install everything in the house. I am also open to other setups or even individual parts but the ebay link seems like it was a decent price for what I was getting and i can eliminate the Netapp JBOD. Since the only thing I would have to add are my hard drives. One of the main reason im looking to buy a completely new setup is to eliminate the downtime of the plex server since I use it for ALL my tv and movies and its also shared to a few friends but if someone has a way I can set it up on the current hardware while keeping the old server running i wouldnt be opposed to saving money.
