June 2, 20179 yr Alright - I'm stuck and can't figure this out. I have an Ubuntu VM that I'm trying to pass through a 2TB drive to. I have the "Unassigned Devices" plugin installed, I've mounted the drive, and added it to the VM. But where does it go? I don't see it mounted anywhere. My Linux skills are pretty rusty so I could be doing something wrong. XML is below - I"m guessing something needs to be changed in there. This is what the GUI generated. <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='writeback'/> <source file='/mnt/disks/WDC_WD20EFRX_68AX9N0_WD_WMC1T1957452/unifi-ubuntu/vdisk2.img'/> <backingStore/> <target dev='hdd' bus='virtio'/> <alias name='virtio-disk3'/> <address type='pci' domain='0x0000' bus='0x02' slot='0x04' function='0x0'/> </disk> Edited June 2, 20179 yr by El Gabito

June 2, 20179 yr Looks to be presented as device hdd on the VM; see if you can see it by typing this on the command line of the VM: fdisk -l /dev/hdd

June 3, 20179 yr Author Well, now it's just broken. Unraid won't even boot. I have no idea what I did that would've caused that, just messing around with an unassigned drive... *sigh*
June 3, 20179 yr Author 1 minute ago, Squid said: Confirm your boot order in the bios. Thanks, good thought. My first thought was to poke around in BIOS - I just have to hunt down a keyboard and monitor. I rarely physically access it!
June 4, 20179 yr To be honest, its not clear what you are trying to achieve here. Can you explain? From your original post, you say you want to pass a 2TB drive through to the VM, but the XML suggests you are trying to use a image file as a disk for your VM and that image file is what resides on the 2tb disk; these are two different concepts... Are you trying to setup a UniFi controller? If so, you could always just use the docker version; works great when installed from the community apps plugin...

I'm setting up a Unifi Video controller, which I'm not sure there's a container for. But yes, the problem is I can't figure out to pass the raw disk through which is all I want. The paths that show "by-id" I could never get to work. If you have any insight into the correct way to do it, that'd be great. Thanks!
June 5, 20179 yr I'm not at home right now, but try this (from memory, so backup your XML first ) you need to unmount the disk in unassigned-devices plugin first. <disk type='block' device='disk'> <source dev='/dev/disk/by-id/ WDC_WD20EFRX_68AX9N0_WD_WMC1T1957452' /> <target dev='hdd' bus='virtio' /> </disk>
June 5, 20179 yr just had a look on hub.docker.com and it seems there is already a docker image for unifi video. see: https://hub.docker.com/r/pducharme/unifi-video-controller/ should be able to deploy the docker image directly.

Or just always search on the Apps Tab (CA) first.

I edited the XML to reflect this, but I get the following error: Cannot access storage file '/dev/disk/by-id/WDC_WD20EFRX-68AX9N0_WD-WMC1T1957452' (as uid:0, gid:100): No such file or directory Any thoughts?
September 23, 20178 yr Author Nevermind - I THINK I have this working! I found this post which led me to this command to get the id: ls /dev/disk/by-id I was getting the previously mentioned drive label from the GUI, when I run this command it is prefixed by "ata-" Once I corrected that, it seems to be working! Thanks for sending me down the right track.
December 16, 20178 yr Author Bumping this again - it worked Sept 23, the day I posted, then stopped working. Somehow the device is becoming unmounted. When I edit fstab to try to auto-mount it at boot, it causes the VM to not boot and I have to remove it. Do I have something wrong with my syntax here? /dev/sda1 /data ext3 defaults 0 2 How can I get it to auto-mount at boot? Is /dev/sda1 wrong maybe? ~$sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL NAME FSTYPE SIZE MOUNTPOINT LABEL sr0 iso9660 829M Ubuntu-Server 16.04.2 LTS amd64 vda 40G ├─vda1 vfat 512M /boot/efi ├─vda2 ext2 488M /boot └─vda3 LVM2_member 19G ├─unifi--ubuntu--vg-root ext4 15G / └─unifi--ubuntu--vg-swap_1 swap 4G [SWAP] vdb 1.8T └─vdb1 xfs 1.8T Should I be using /vdb/vdb1 instead? If it's not clear - I'm sort of a noob when it comes to this stuff... Edited December 16, 20178 yr by El Gabito
December 16, 20178 yr Author I think I figured it out - changed fstab to be what's below - /dev/vdb1 /data xfs defaults 0 2
