I saw this:

Currently I have 1 m.2 as a cache pool and another m.2 as a cache pool. The second cache pool is where I run dockers and vm's. I am concerned about hardware failure and would like to be better prepared. I recentl;y watched this video Now my motherboard only has 2 m.2 slots available. I have looked at pci expanders but I had a different idea. I have available sata ports on my motherboard. So here is my idea 1. Replace the existing Pool1 m.2 cache drive with a sata ssd. 2. Move the m.2 cache drive to Pool 2 (that makes it 2 m.2 cache drives in pool 2. 3. Take Pool 2 and convert it to ZFS (I have a lot to learn about ZFS) Configure ZFS to better protect the Pool 2 cache. Am I on the right track. Any suggestions? Thanks Bill

Thanks for the clarification

Well it has been stable for a few days. I had ordered new ram and that is what fixed it. Thanks to eveyone that took the time to help me out!

I'm down to big items the motherboard and processor. I have a replacement motherboard on the way but if its not that, I could buy a different/replacement LSI card. Other than that might begin to get real expensive. What bothers me, is when I find a server is shut off, I know something is up with the power supply. When I did the swap I had an older 650 psu from my old unraid server. It lack 1 -4 pin 12 volt connector. I had read depending on CPU the motherboard might not need that connector. Well the server booted as normal and began crashing just the same. Do you think I am pretty solid that it isn't the power supply.

I am wrong the issue has not been resolved. My unraid server continues to crash. Here is what I observed: Scenario 1- I have a LSI SAS9220-8i. I eliminated this by moving all the drives to the onboard motherboard sata controller. What I observed here is the server would crash every 3 minutes. After researching I started thinking this issue could be caused by using all the onboard sata ports plus having 2 m.2 drives. I have read that when using the m.2 slots coulkd affect some of the sata ports. Am I correct or incorrect in my thinking? Scenario 2- SO I moved and reconfigured my drive from the onboard controller to the LSI SAS9220-8i. It stopped crashing, or so I thought. When I reinstalled the plex docker, the server began crashing again. Note this is where it all started. Now I am wondering if this could be the issue. I have the LSI SAS9220-8i in a PCI X1 slot. Note I have had this card in the same slot for 3 years with nothing but stability. I have owned the card since unraid version 4. Could the issue be that the LSI card in a PCI X1 slot be the root cause. Interesting fact what I observed when the server crashed in each scenario Scenario 1- The server would crash as in I could not access the gui and could not ping the server. I had a monitor on the server. I could see the screen but could not type on it. Scenario 2- When the server crashes it powers off. I am down to the following possible root cause The LSI board The Motherboard The processor I have changed ram, power supply and eliminated all unneccessary drives. Any and all ideas are welcome

To update I finally figured it out. To be short it was my fault. I hae a LSI 9220-8i. I was using a expander from long ago when I had over 10 drives. Things worked well back then. Today, Unraid did not like this expander. In fact I figured it out after (I can't count how many hours of research) I saw a picture of the same expander with the caption "do not use with Unraid". So I reconfigured my drives and everything returned to normal. By the way from anyone who is doing research because of strange crashes, there was nothing in the logs to indicate this was the issue.

I have been researching Bifurcation. I am looking for technicalities to watch out for including suggested adaptors. I emailed Asrock and confirmed my board supports 8x8 & 8x4x4. So what does this mean, does it mean I could have either a 2 port adaptor running the nvme at 8x8 or a 3 port adaptor running at 8x4x4? I probably am not quite understanding the concept yet. I have read there are raid and not raid adaptors, can a person use either. My end goal is to protect my cache that has my dockers and vm's. Currently I have 2 m.2 cache drives. 1 for normal cache. 1 for dockers and vm's. Thanks for the information in advance

I have a vm that won't boot. I played around at one time with passing through the igpu with Igvt. I am getting this error device not found: mediated device I have been looking around but either overlooked the fix or have not found it yet. I don't want to pass through the igpu would like to get the vm to boot without have to rebuild it. I really appreciate any help you can provide

So I replaced the M.2. The server continues to crash every 3 minutes. I am down to motherboard or processor. I am looking for a replacement motherboard. Got any ideas to determine processor versus motherboard? This is a nice versatile setup. It is a Xeon 1290p. Sad I am having these hardware problems after only 3 years of use.

I have a Asrock Rack W480m with a Xeon W1290.p. Long road of troubleshooting I believe the motherboard has an issue. The setup is only 3 years old. I was looking for a different motherboard as a suggestion. It doesn’t look as though many are available. I currently run some dockers and vm’s. I use 2 m.2’s as cache. Any suggestions would be greatly appreciated it.

If I start the array in maintanence mode, it does not crash. I wil say tht ping rates fluctuate. i have 2-m.2 cache drives. What would be the best/safest way to eliminate the m.2 and yet still be able to renabe the drives as cache in the furture if they prove not to be an issue? One cache has my domains and appdata shares.

I change ram, no defference. I remove unneccessary drives no difference

I guess if this is a hardware issue, then its either ram or motherboard.

I have done some pretty drastic troubleshooting. I changed power supply, no change. I moved the drives to the onboard sata controller, no change. I rebuilt a new install of unraid with a backup usb, no change. I downloaded the diagnostics. The behavior did change recently, basically I lose ping and cannot access the server. tower-diagnostics-20230402-1109.zip

Now my server is just crashing. I managed to grab a log. Would someone look at the bottom of the log and see if you can tell what is going on syslog-192.168.2.97.log

I have been having an issue wih my entire server crashing when Plex docker is enabled. I started by looking for hardware issues originally but have seen the server run as normal as long and plex is not runniing. I have trie various dockers with no change. I have seen it crash the entire server scanning movies. I enabled syslog to see if someone could help me track down what is going on. Right now I am at a loss as to what is happening. I even installed Plex on a different computer and told it to scan the same files, it did not crash. So I don't think there are corrupt files syslog-192.168.2.97.log

Actually I found the syslog, can someone take a look and see if you see a problem syslog-192.168.2.97.log

Well I know it is the plax docker. I have done a lot of uninstalling and installing other plex dockers. I am not making any progress resolving the crash. If the plex docker is enabled it crashes during the default maintenance window 3-5am. I installed plex on another computer and had it scan the same movie file and it did not crash. So I think that eliminates corrupt files. I am stumped on the next step. I enabled the syslog server but I do not see any logs in the share i told it to use. Have you made any progress?

I am looking for a solution myself. Linucserver.io Plex docker is crashing my server during maintanence

I have been running the linuxserver.io plex docker for a long ime. Since I did the recent updates, this docker has been crashing my Unraid server. I haven't had any problems up until these recent updates. I haven't made any changes. I did considerable testing to prove I dont have any hardware issues. I can watch a movie fine, it is when plex is doing maintenance between 3am and 5am. It will literally crash my entire server. Anyone else experiencing this same problem? I am currently considering uninstalling and reinstalling to see if that helps. I am also looking for a good procedure to uninstall this docker and keep the watch/unwatched information in Plex.

If this is any help, I have the Plex docker. I have been having weired reboot crashing. I traced it to the Plex docker. I have the linuxserver.io version. I am in the process of figuring out what to do next. I believe it was an update to the docker that broke it.

Thanks for the reply. I enabled the syslog server (local). The server shutdown between 3-4 am. I looked for a log in the share and didn’t see anything.

I currently began having weird issues with my sever. The past 5 days I have seen the server reboot once. Since then I have been seeing it shut completely off. This leads me to most likely a hardware problem. Upon restart, the array starts fine. A parity sync begins. Between 6-8 hours later the server shuts off. I guess what I am looking for, is logs to browse through to see if something in the OS is shutting down the server. I have confirmed this is not a "heat" issue. I appreciate anyone willing to help trouble shoot this issue

Ok here it is. Thank for your time tower-diagnostics-20211110-2126.zip
