xxredxpandaxx Posted January 15, 2017 Share Posted January 15, 2017 I have a couple old drives (pre fail disks) laying around and I wanted to use those for some non critical vms. Can I have the disk not assigned to my array or cache array and still use it somehow? Sent from my iPad using Tapatalk Quote Link to comment
1812 Posted January 15, 2017 Share Posted January 15, 2017 Yes, just change the primary vDisk location to the drive you want it on. Quote Link to comment

JorgeB Posted January 15, 2017 Share Posted January 15, 2017 Assign the disk to the cache slot or leave it unassigned and use the unassigned devices plugin. Quote Link to comment

SpaceInvaderOne Posted January 16, 2017 Share Posted January 16, 2017 You can either put vdisks on the unassigned drive or pass through the whole disk as a block device for exclusive use by a vm Quote Link to comment
darianf Posted January 16, 2017 Share Posted January 16, 2017 You can either put vdisks on the unassigned drive or pass through the whole disk as a block device for exclusive use by a vm If full disk is to be used by the VM, which is the preferred method? or what are the advantages of one method against the other? (performance, stability, etc..) Does it matter if it's ssd or standard HDD? Thanks -d Quote Link to comment

You are removing one layer of virtualization. I also prefer to pass the whole raw disk and partition it in the VM OS but you can also just pass through a partition. So you could have multiple partitions passed to multiple VM's but with a drop in performance. The fastest a side from passing a sata controller, would be adding whole SSD. The performance difference between SSD and HDD would be the same as any other computer. Quote Link to comment
darianf Posted January 16, 2017 Share Posted January 16, 2017 thanks for the good explanation dmacias. i think now it really makes sense to buy the ultra cheap small ssd, like 120 GB, and pass them entirely Quote Link to comment
JonathanM Posted January 16, 2017 Share Posted January 16, 2017 thanks for the good explanation dmacias. i think now it really makes sense to buy the ultra cheap small ssd, like 120 GB, and pass them entirely Depends on how close you are to your server limits. Since Unraid counts all attached devices for the license, you could find yourself needing to upgrade either hardware or software to add more drives, where if you have one large SSD, it only takes one SATA port to host multiple VM's.

darianf Posted January 16, 2017 Share Posted January 16, 2017 is it my [wrong?] understading that unassigned devices do not count against the license limit, since they are not part of the array... somebody can clarify please? Quote Link to comment

jang430 Posted March 4, 2020 Share Posted March 4, 2020 What if I only want to assign a portion of the SSD (unassigned devices)? Will create several different VMs on it. How do I do this? During creation of VM, what drive to I assign to it? I've pre-cleared my SSD already. Quote Link to comment

UD mounts are under /mnt/disks/[mount name]. Mount name can be found (and changed) on the UD screen on the Main page. Don't preclear SSD. Poor thing just wasted write cycles. 1 Quote Link to comment
