I updated to unraid 6.9.2 the same time i added a new 1tb samsung ssd as cache. After the update I found that the sonarr webUI didnt work. All other docker seemed to work fine. When i tried to restart the docker nothing happened. At that point all other docker just stooped working as well. While the unraid webUI in general worked, starting stopping dockers or even restarting the server did nothing. At the time i just cut power and restarted the server. Everything seemed to work just fine. A few hours later the sonarr webUI didnt work yet again. Long story short everything repeated over and over again with basically no change.
At some point i thought maybe the cache drive was the problem since i read somewhere that someone (specific i know...) had a problem with his. After trying to clear the cache so that i can disconnect it, the server froze a few times. Either the ui didnt update anymore and wouldnt load anything or the site just crashed. But the server didnt shut down you could clearly hear the disks spinning. Sometimes some of my shares just vanished including appdata and system. Other times the shares tab didnt load but had a error massage (see picture). That made me believe that maybe the cache drive had issues. After finally removing the drive i had high hopes. But just like before a view hours later the sonarr webUI didnt work again. Its clear that something is wrong and the cache wasnt the issue.
While all that happened i looked at the syslogs (/var/log/syslog) a few times as well as htop. What seemed odd here is that sometimes certain processes used 100% cpu (which in itself is odd since what actually happened is that one core was at 100% per one proocess that had "100% cpu usage"). The processes came from docker that didnt work at the time. But not everytime a docker didnt work there was a process with 100% cpu usage. The second oddity i saw in htop was a process that started approximately when the docker stopped working. its "command is "/usr/bin/dockerd -p /var/run/dockerd.pid --log-level=error --storage-driver=btrfs".
Since all docker are effected i dont think its a problem with a specific docker but with unraid itself (or anything else but the docker). I dont know what todo at this point and i would appreciate any help. If there is something else i can provide iam happy to do my best to do so.
As a side note I also noticed that some of my files got corrupted. I could only see that on pictures but i think some videos as well. Thats obviously a big issue and nothing you can take lightly.
**edit**
when copying the file to my pc and than opening it nothing happens and the picture has no corruption... I dont understand how that is even possible. I copied the file to my pc, deleted is from the server and copied it back. Now its not corrupted when i open it on the server?!
I attached the shares error massage.
