I'm having the strangest problem. Yesterday there was a power outage and I wasn't able to shut down properly. When the power returned, unraid started acting weird. First my USB pci card is only showing 3 of 4 ports in the vm management pages. Secondly when I start my primary vm, win10, it is showing most cpu cores at 100% and the vm acts very sluggish. I shut down the vm within windows and the whole server then shuts down. Third, all shares that are mapped are unable to connect yet if I attempt to access those shares using another computer they do in fact connect. I feel something got corrupted and I don't know what to do. 

Try to get a Diagnostics files (when all the problems are occurring if possible) to attach to your next post.  That might provide clues to the Gurus trying to help you. 

I will do so if I can get it to boot up long enough

Try booting in safe mode if needed.

 

Side test, load up trial on another USB stick and try it out.  If things fire up, your stick may just got corrupted and possibly fixed by reinstalling from backup.

Oh this is a good idea. I was able to get a diagnostic that I'll post in a bit. But I will try the trial. I do have a back up I recently made when I upgraded to 6.12.

I was finally able to get some time to try to troubleshoot things.  Also to get the server to stay powered up.  I was able to get a diagnostic file which I will post here.  What I have found is that I can get the array started and the server stays up as long as I dont turn on the docker containers.  I am going to try to run a few containers today and see what happens.  I was able to update a few containers but when I got to Krusader and it was extracting the last packet I received a docker utilization error, about %74, and the system powered off.  When the server came back online it started a parity check which then powered it back off.  I have found a few articles stating a possible back psu that maybe works until it gets overloaded.  Could the psu have broken when powered off during the outage?  I have noticed a few times after shutdown that if I attempt to power on right away it'll simply stop. power on, stop, wait a minute and then power on and it's ok, until it seems that I am pulling more power due to increased usage of the machine.  I am thinking I'll order a new psu today and at least attempt that.

 

Another oddity was that I have a 4 port usb extension card that one port no longer shows up in the vm section down at the bottom.  I had something plugged into that port that also had an auxiliary power supply for a game controller to give the unit more power.  This second power supply was not plugged into the UPS.  Could that have damaged the usb port when the power returned?

Thank you!

UPDATE

OK so since this all happened the server sounded very quiet.  The fans were not as loud as normal.  Today I bought a new PSU thinking maybe there was an issue with not enough power getting to the server for everything.  While I am awaiting the delivery I tried launching the server again to see what it takes to shut it down.  It wasn't liking a parity check or running updates or too many dockers.  I decided to take a look at the fans and see why it was so quiet.  I come to find out the CPU fan was not running.  I gave it a little flick and now the server appears to be back to normal... almost.  My 4 port usb card seems to have lost one of the ports.  I do have a new card coming tomorrow as well that is a bit updated and I may still upgrade the PSU, just in case.  No idea why the fan was stuck but I may end up replacing it as well.  So in theory, the cpu got too hot and not enough cooling happening and it powered down to protect itself.

Do this or replace the CPU cooler.  Any fan  used in a computer will eventually fail.  Usually, they fail to start spinning as the starting torque on that type of motor is very low.
