@gsamu OK, at least you are up and running again.
Re:
Fine if you ensure they have a serial. qemu sata emulation ensures a serial is assigned. But note that Rockstor tracks devices by their serial so in passing real drives through as virtio you may end up with a different serial so it’s like the entire pool may have been ‘ghosted’ by a look-alike pool member set with all different serials. I’m pretty sure v4 (and later stable v3) can cope with this however as we have recently had improvements in coping with such arrangements.
Essentially as long as the device ‘looks’ the same then all should be good. The vast majority of Rockstor development is done on virtio and sata emulation within qemu. See the following technical wiki entry for our device management:
“Device management in Rockstor”: Device management in Rockstor
Subtitled “Rockstor’s Serial Obsession”
We follow udev and it’s requirements for generation of by-id names.
Hope that helps.
