HELP - Windows File Explorer Crashing and Slow Navigation

[Else89]

Been running a VM with TrueNAS-13.0-U4 installed, it's got 2x 10TB Segate HDDs running raid 0 (yes i konw) I use it for large video files that are not important.

When trying to access the mounted drive it will take 15 seconds to navigate around the file structure and I will have crashes in explorer when trying to copy any data too it.

I've got 8 CPU cores allocated and 24GB of ram so reseource wise I don't think this is a problem

When accessing the share I see the CPU graph max out while it's accessing the share. Really unsure on where to go, restarting does help for around 2 minutes.

I believe the issue started on the most recent update but i have nothing to back that up.

I'm still rather new to TrueNAS and NAS in general.

I've attached as many screenshots as I can to help. Any help will be appricicated.

I've rebooted the host machine and the VM multiple times.

PC Specs -
Ryzen 7 2700
64GB Ram
GTX 960
Windows 10
NAS running in Hyper V

How are you passing the drives to the VM? This is probably your problem. The only good way of passing drives to a TrueNAS VM is via a PCI-E passthrough of a SAS HBA, with the drives connected to the HBA.

Hi, thanks for the reply, this has been working for around a year or slightly more with no issues, i'm using the IDE Controller with Hyper-V (attached) Seems strange for this to suddenly be an issue. Ideally I don't want to go and throw money at this problem when it has been working perfectly fine.

Yes, this is the problem with this sort of passthrough. It will appear to work initially, and then go south over time. TrueNAS expects to have direct control of the drives, but you're interposing Hyper-V between the drives and TrueNAS.

Please do not run FreeNAS in production as a Virtual Machine!

Thank you for the advice here, after being on a support call with somone for 3 hours yesterday we can see that there is no issues from a windows 11 machine but only windows 10 machines. It seems to be a login error even though all details are correct within windows. We have decided to try a fresh install and see where that goes with TrueNAS
