Hello, An LVM System Datastore has been added to the system (iscsi lun presented to kvm nodes). While instantiating VM from the template the following error has appeared: `one.vm.deploy result FAILURE [one.vm.deploy] Image Datastore does not support transfer mode: fs_lvm` Configured Image datastore (NFS shared): `DATASTORE TEMPLATE` `ALLOW_ORPHANS="NO"` `CLONE_TARGET="SYSTEM"` `CLONE_TARGET_SSH="SYSTEM"` `DISK_TYPE="FILE"` `DISK_TYPE_SSH="FILE"` `DRIVER="qcow2"` `DS_MAD="fs"` `LN_TARGET="NONE"` `LN_TARGET_SSH="SYSTEM"` `RESTRICTED_DIRS="/"` `SAFE_DIRS="/var/tmp"` `TM_MAD="qcow2"` `TM_MAD_SYSTEM="shared"` `TYPE="IMAGE_DS"` Configured System datastore (LVM): `DATASTORE TEMPLATE` `ALLOW_ORPHANS="NO"` `BRIDGE_LIST="one-kvm-node-01 one-kvm-node-02"` `CLUSTER="100"` `DISK_TYPE="FILE"` `DS_MIGRATE="YES"` `RESTRICTED_DIRS="/"` `SAFE_DIRS="/var/tmp"` `SHARED="YES"` `TM_MAD="fs_lvm"` `TYPE="SYSTEM_DS"` Could you help to solve this issue? * * * KVM Nodes OS: Centos kernel: 3.10.0-957.21.3.el7.x86\_64 Opennebula: 5.8.1 ---

Hello @gray380 Do you need to change your TM\_MAD in your image datastore to **fs\_lvm** , visit [this](http://docs.opennebula.org/5.8/deployment/open_cloud_storage_setup/lvm_drivers.html#create-an-image-datastore) for more information. ---

Hello @ahuertas, Do I have to change image ds type despite that in reality it is NFS shared? ---

You can have both, so just change TM\_MAD or TM\_MAD\_SYSTEM, so, you can have lvm and shared at once. ---

Okay, I’ve change Image DS’s TM\_MAD from qcow2 to fs\_lvm and faced the other error: > Mon Aug 5 15:25:47 2019 [Z0][VMM][I]: error: internal error: process exited while connecting to monitor: nly=on -device ide-cd,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -chardev socket,id=charchannel0,fd=28,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=org.qemu.guest\_agent.0 -vnc 0.0.0.0:239 -device cirrus-vga,id=video0,bus=pci.0,addr=0x2 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 -sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,resourcecontrol=deny -msg timestamp=on > Mon Aug 5 15:25:47 2019 [Z0][VMM][I]: 2019-08-05T12:25:47.661101Z qemu-kvm: -drive file=/var/lib/one//datastores/119/239/disk.0,format=qcow2,if=none,id=drive-virtio-disk0,cache=none: Image is not in qcow2 format Seems that opennebula works only in the following combinations: LVM Image DS → LVM System DS Shared qcow2 Image → Shared System DS in other words mixing not supported. ---

Yes, the image datastore you are using.
