I am real sorry you are having this issue. It can be pretty scary when your system starts to have problems. I am not attacking you and I would like to help. Just to set the context of my post, I have been on 6.8.3 ever since it has been released (about 5 months) My system has been rock solid. Maybe you should change the name of this post to "Unraid not functional after upgrade to 6.8.3" or something like that. I agree with bonienl who is helping you through this that it is not software, so if it is not software it is hardware. I looked through the post and could not find your diagnostics. You might want to post diagnostics so that we can see how your system is booting. So here are my thoughts. Slowness from UnRaid might indicate a bad or filled up flash drive. I just experienced this issue a few days ago, while I was doing a pre-clear, the whole unraid interface was corrupted with errors reporting unable to write to files. I ended up stopping and starting the web interface engine to clear it up. But I don't think that is the issue. If your flash drive is having issues this could cause the slowness and corruption you are seeing. Have you tried to boot the flash drive in another system? Yes it will not start because its missing the drives, but I was thinking that either the Flash drive is dying or the USB port is going out. UnRaid runs in a RAM disk. The other possibility is that you have bad RAM. The RAM disk is created in this bad area of RAM and becomes corrupted. If you boot this USB into another system, and see an improvement, you can eliminate the flash drive as the problem and think about the USB port or bad RAM. If you still are having the problem, you could back up your config folder and reformat the drive, put 6.8.2 back on the USB drive and copy your config folder over and try that. It is possible that the upgrade went sideways becoming corrupted. DO NOT use another flash drive, the license will no longer be valid on that new flash drive. Reformat the old Flash drive and copy the config over to that freshly formatted flash drive.

I attempted to pre-clear 3 1.5TB drives I picked up from a friend whom was not using them any more. After i started the Preclear (using the plug in from Community apps) 2 hours passed and the output slowed to 90mb a sec. the unraid web interface became corrupted. I had to restart those services to get control back to my server. I noticed in the log that the array is now out of space. Lots of errors where it attmpted to write data but 0 bytes were written. I did not have much to begin with but I had not realized that it would use what remaining space is on my array to make all the fancy graphics work correctly. How can I fix this. Can I redirect at least temporarily where these files are stored to the cache drive so I can get these drives tested and into my array? Should I use BinHex's preclear docker instead? I liked the other plug in because it integrated so well with the unraid GUI. Sincerely, Sideband Samurai

If it is a new drive, I would pre-clear your drive first to make sure the disk is healthy. Once that is successful, then you can add it to the array. The Preclear plug in is available from the community applications "Apps" tab at the top. If you don't see "Apps" then install that plug in first, then install the preclear plug in, then preclear your disk. I am pretty sure you know this as well but your parity disk must be the largest disk in your array. If the disk you are installing is smaller than the other two, its not going to work.

I wanted to post this experience I have had with my hardware. So that users of Unraid can learn from this. Unraid is terrific, no problems there. What I did notice, when I started one of my bluray movies, after a couple of minutes I would hear an alarm come from my server. Looking at the IMPI logs, it kept telling me that my CPU temps were high (93 C). I looked inside the case, the fan was spinning, and i had recently blown the dust out of the system, so everything "looked" normal. The server had been up and running for 5 years solid with no issues. I ignored the error, until my wife mentioned it to me. She told me that just about everything she plays through Plex causes the alarm to go off. So I ordered a new CPU / FAN heat sink. I was using the old intel snap on that I did not care for very much so I figured it was time to change it. I went to amazon and ordered a Noctua NH-U12S. I was worried that the cooler might be too tall but if it did not fit I would run with the cover off. I discovered later on I had nothing to worry about, I had almost 5 cm of clearance to the cover. The part came in and I pulled the server, warning my wife no internet was available while I fixed this issue. This was a two hour project, because I needed to remove the system board to install the new cooler. After I removed the system board it looked like the push pins on the cpu cooler had come out of the holes on the system board. After removing the cooler I had discovered that the cooler had indeed popped ever so slightly off the CPU causing the cooling issue. Also the thermal paste was hard as a rock. I removed the old thermal paste with 99% IPA, applied the supplied Noctua paste and installed the hardware. Now I don't have any more Hi temp warnings from the CPU. As a matter of fact, my CPU routinely runs at 37C even under load. My lesson is pay attention to those warnings some boards have. Mine is a Supermicro X9SCM with 32 GB RAM. Had I taken the extra time to look more carefully I would have not had to deal with the warning tones all the time. Fortunately for me, no damage occurred as I am pretty sure the CPU was throttled during the over heat warnings.

Did you setup shares? in Unraid? SpaceInvaderOne on youtube has an excellent unraid setup. Take a look at those videos.

Based on how SMR works, I guess I would not want to have an SMR drive for parity. Maybe for other data but not parity.

You know these cards are all over ebay for around $40US dollars. I just bought a "LSI 6Gbps SAS HBA LSI 9200-8i" for my system. This is the IBM version the seller even flashed it in IT mode for me. No need to pay 250.00 or 150.00 for these cards. The seller I bought from sells them new in the box for that price.

Yes but if China invades Taiwan a lot of computer components will be in jeopardy.

I looked at the forums.serverbuilds link and found it was in USD.

Thank you for the advice and I will keep this in mind when posting to old threads.

Yes that appears to be my problem. Take a look at this screen shot here. That device matches the error I was getting from the VM startup.

Oh, I know now what is wrong, I am passing through the 4 port Ethernet card to that vm, so I can see where that would be a problem. I will take a look at this.

When I remove the new card everything works normally, the Firewall VM loads and all dockers load. I also noticed this exact problem when I moved the HBA from the right most slot (closest to the cpu) to one slot over. I believe the original slot was 10 and the next slot over was 11. is there a way to change the behavior? Thank you for your assistance on this question.

I recently purchased an LSI 9200-8i so I can add more drives to my server. I currently have installed LSI 9211-8i which has been my main HBA since I installed unraid about 5 years ago. I installed the LSI 9200-8i without drives in anticipation of plugging them into my drive cages so that I can just add drives as needed. I started unraid, everything came up normal except for the docker containers and and the VMs. When I try to run the VM (which is my firewall) it reports the following:

I apologize but the thread really applies to me. Instead of creating a new thread I thought I would keep the thread going so as to keep all the knowledge in one place. Maybe not the best thing to do but the forums are a repository of knowledge, its better to have one thread that has the answer then have many small threads you need to paw through just to find the answer. If I have done something wrong, please let me know. Besides, I did not bother to look at the date. 😚 My system has 6 drives and a parity. I have had this server running without any issue for 5 years. Disk 1 through Disk 3 and Disk 6 are at 100%. Disk 4 and Disk 5 are at 99%. I am going to purchase larger drives shortly but right now budget does not allow for it. Anyway when I start upgrading the drives, right now they are a mix of 2TB and 3TB drives, would it be a good idea to move some files on these older drives over to the newer drives. Say keep moving files until the capacity is at least down to 90% for each drive?

Wasn't it dangerous to have the drives fill up completely to 100%?

That card is only a 4 port card. Those models are only designed to fit into small enclosures. You should be looking at LSI 9240-8I 6Gbps SAS HBA. Such as this one: https://www.ebay.com/itm/LSI-9240-8I-6Gbps-SAS-HBA-LSI-9211-8i-FW-P20-IT-Mode-ZFS-FreeNAS-unRAID-US/133123367829?_trkparms=aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D225074%26meid%3D0d2fc60252eb4d1c8404562cfd8f2dd2%26pid%3D100012%26rk%3D3%26rkt%3D12%26mehot%3Dag%26sd%3D224011559187%26itm%3D133123367829%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv5PairwiseWebWithBBEV2bDemotion%26brand%3DLSI&_trksid=p2047675.c100012.m1985 Yes its a bigger card but these cards are designed to be installed in servers and handle 8 drives. If you have a very small case, I would recommend a nice mid tower. I got 15 drives in mine. If you only have 1x pcie slot I would recommend NOT using that slot as it performs very poorly with hard drives. You could experience excessive pre-clear times because there are not enough data lines to support your drives. You have not told us what motherboard you are using, or the case. I am curious what you are using.

if you run unraid, then after the system is booted go to the terminal (ssh) and type in lspci as you did in Manjaro and you will see them. The issue is flashing them. You can only flash one card at a time. Simply remove the card in the 2nd slot and then perform your firmware update. Remove the freshly updated card with the other card and flash that card. Now install the remaining card in the system and unraid should show both cards.

Though you are correct, in California, you could walk out of any store with a big screen tv, as long as its under 1,000 nothing will happen. And even if they catch you, and prosecute you, you can get out of jail free with no bail. Now this is a small exaggeration but I have seen people walk out of home depot with faucets and what not, all they do is either recover the merchandise or let you walk away with it. I have seen major retails like Stator Bros close their stores in high theft areas because of this. Then the shop lifters go to the nicer neighborhoods, and the store has to be modified so there is only one Entrance / Exit to control loss.

Thanks for the answer, the reason I asked is with the new 10TB drives it could take longer than a week to actually verify the drive once. I like using 3 cycles as well. I was just checking to make sure this is still the standard practice. I built my system with 3TB green drives when they were all the rage. Now that its full, instead of adding more drives, I thought to upgrade them. I will move the 3TB drives further down the array as I upgrade each drive so they will not sit on my shelf.

I was curious. I am about to buy a 10TB hard drive. Is it still good practice to pre-clear the drive. If so, then how many times should it run through that process. My Unraid has WD Green 3TB hard drives and I am going to start upgrading them. So of course I will be starting with the Parity drive and working my way up from there.

Fortunately nothing here is irreplaceable. This is a media server with all his DVDs on it. we can always rebuild it from scratch if we need to.

Thanks for this, unfortunately this is a server I am fixing for a friend. I helped him set this up and he started having issues. It sits in my closet until he can get replacement drives to repair the array.

As a second thought. Unraid update module should not be asking to update a module that has been updated for a release candidate. It simply should not be on my radar unless I enable a feature "Bleeding Edge Updates" or something like that.

LOL, oh well, have to live with it until 6.7 comes out. Thank you for responding.
