juan11perez Posted November 1, 2019 Share Posted November 1, 2019 Good day, looking for some advice/recommendation. I have a number of vms running of the cache drive; which is also running dockers. The Vms are passed to AMD and Nvidia cards; for the most part it's stable but every now and then when windows throws an update it breaks the vm which in turn breaks everthying! As a side note I must say Unraid's rebuilding capability is fantastic. This little scenario has corrupted a data drive (rebuilt); the parity drive (rebuilt) and even the OS usb (rebuilt). I've been able to recover everthing every time. Anyway I think I'm pressing my luck, so I thought about moving all the vms onto an unassigned device and was looking for some feedback/experience. I understand it cant be completely isolated as the vm service wont start without the array, but if I moved all vm associated files/directories away, I pressume I'm mitigating the risk significantly? Thank you. Quote Link to comment

Thank you. I do not think that running from a UD drive will affect stability in any way. Quote Link to comment
juan11perez Posted November 1, 2019 Author Share Posted November 1, 2019 @itimpi thank you for your note. Apologies if i'm not following. So is your opinion that moving to UD wont improve the situation? If that's the case can you offer any suggestion? Thank you again Quote Link to comment

Thank you again All that change does is move the files to another drive, and do not affect stability. It would only be worth doing if you wanted to reduce the I/O load or the space used on the cache drive. No idea what might improve your stability I am afraid. Quote Link to comment

AnnabellaRenee87 Posted November 1, 2019 Share Posted November 1, 2019 Only problem I see is redundancy. With your cache array you have options like RAID 0, 1, 0+1, 5 AND 6. Then again you could pass a hardware RAIDed array as one big disk for the OSes. I do RAID 5 on my cache array with 3 SSDs, one drive can go and it will rebuild once replaced. Quote Link to comment
juan11perez Posted November 1, 2019 Author Share Posted November 1, 2019 @AnnabellaRenee87 thank you for your advice. I'm not overly concerned with redundancy as I back up the vms to the array. I was just trying to think of a way to mitigate any "damage" when the windows vms act up. Quote Link to comment
