james25182 Posted September 8, 2015 Share Posted September 8, 2015 Hi, I'm running unRAID v6 on an HP Microserver G8 with 4GB RAM. I recently added a Windows 7 VM as I want to run some windows only apps but I found that every morning I was coming in to find that unRAID was completely hung. I have to hit the power button to reset the system as the webGUI is unresponsive, I can't log in via SSH and the local console hangs before even asking for my password. As the syslog is refreshed when the server restarts, I can't get any useful information from that but when I restart the Windows VM the Windows event logger shows an "Windows was not properly shutdown" at some time shortly after 3am each day. I've attached a diagnostics zip if that helps. Can anybody help me find what is going on? homeserv-diagnostics-20150908-0943.zip Quote Link to comment
trurl Posted September 8, 2015 Share Posted September 8, 2015 4GB is a little tight for just running Windows 7 bare metal. Quote Link to comment
james25182 Posted September 8, 2015 Author Share Posted September 8, 2015 Agreed 4GB isn't ideal but I've only given it 512MB and it actually runs OK. Is that likely to be the cause of the whole unRAID system hanging? Shouldn't the VM be kept separate from the host OS? Quote Link to comment
mr-hexen Posted September 8, 2015 Share Posted September 8, 2015 Make sure your cache share is set to ONLY for the VM. Right after 3AM is about the time Mover runs. Quote Link to comment
james25182 Posted September 8, 2015 Author Share Posted September 8, 2015 Thought I'd done that already as that was my first thought but it turns out I didn't. I've set it to only use the cache disk and excluded using the other disks in the array. Let's see what happens overnight. Quote Link to comment

Chances are this was the root cause, but curious as to why because the mover should be ignoring open files. Nonetheless, let me know what happens overnight. Quote Link to comment
james25182 Posted September 9, 2015 Author Share Posted September 9, 2015 Well it didn't crash last night so I guess it was the mover service causing the problem. Like you said, it shouldn't move open files and shouldn't cause a host crash so still some mystery there. Quote Link to comment
