Hi - I have couple of older drives that I want to pass through to my Win 8.1 KVM and use these for backups. I noticed that for a large number of smaller files (like pictures) it was better to have them in a local VM drive for quicker access and Lightroom likes it as well. This also serves as a backup for the critical media content for which I'd like multiple backups.

 

Is it possible to mount the drives using SNAP that are passed through to Win8.1 KVM? If I could do this, running rsync to get backups from /mnt/user would be easier. I passed through the drives using the xml code (below), formatted them in Win8.1 as ntfs. I noticed couple of issues:

 

a. One of the drives shows up as ntfs in SNAP and other shows with an older reiserfs format.

b. I copied few files to these two drives in both unraid terminal window and in Windows. The files copied through terminal do not show up in Windows and vice-versa for both the drives.

 

This makes me think I cannot access the drives in unraid if they are passed through. Is this behavior expected and what other easier options there may be to do rsync of files between HDD passthrough and /mnt/share?

 

xml code for HDD passthrough:

	<disk type='block' device='disk'>
    <driver name='qemu' type='raw'/>
	<source dev='/dev/disk/by-id/ata-WDC_WD15EADS-00S2B0_WD-WCAVY1215789' />
	<target dev='vdb' bus='virtio' />
</disk>

I think what your asking is if you can mount a drive in unRAID and in windows. If that's the question then no. Mounting a partition in two different operating systems will cause corruption. The only way is with a cluster file system or networking. If it was linux you could do 9p file sharing.

Thanks dmacias, I figured as much. As you guessed, the files in the disk got corrupted, no big deal as I was just checking with samples files. I am using Windows, so I am out on 9p sharing. It would have been nice if M$ included the 9p sharing ability in Win 8.1.
