I have done so a couple of times, without issues, but not on our Proxmox 
deployments. We use mdadm for VM data only, root/boot partitions are on 

I have even recovered a mdadm softraid1 data from a failed Iomega 
storcenter ix2 NAS that was in the process of recovering de raid1, just 
pluging the disks to a regular PC.
