qcow2 image with >2TB ???

[jagan]

Hi Guys,

Need help, Can't able to add more than 2TB (>2TB) size disk to VM in qcow2 format on WEB GUI.
I am having 4TB disk, connected has Directory model to proxmox host, need to add single 3TB partition to windows VM in qcow2 format.

Since i have experienced worst performance with vmdk format compared to RAW & Qcow2, Pls anyone can help me to add 3TB disk in Qcow2 format.

Thanks in Advance...

i am using proxmox 3.4, In web gui i tried to add 3TB disk in qcow2 format from Directory storage . But i am getting the below error. For RAW format also same error and only VMDK format is accepting.

If you are on PVE 3.4 you are using ext3?
ext3 support max 2TB files.

ext3 limiting the size ? how the VMDK format is allowing to add more than 2TB file.
If i re-attach the disk with ext4, will it accept for both Qcow2 & RAW format.
