Hello, I have a problem with disks passed to VM. VM is Linux with OMV installed on it. Disks are passed to VM. They're connected via LSI controller. Unfortunatelly my motherboard doesn't support IOMMU so I can't passthrough full controller - that's why disks are passed separately.
After upgrade to Proxmox 7 filesystems (ext4) on passed through disks are getting corrupted - VM starts (it's filesystem uses SSD connected via SATA to host) but Linux stops in maintenance mode because of "not cleanly unmounted disks".
I've managed to fix filesystem on one disk using fsck. The problem is, after I start VM, filesystem is getting corrupted again. Of course it was not a problem on Proxmox 6.4.
Currently I don't blame Proxmox 7, I just need a help to identify, what's happening. Is it problem with Proxmox, VM, Linux on VM, controller, kernel? Pls help me identify problem.
