Export ZVOL from Truenas Scale

[netspear.io]

Hey, I'm trying to export a zvol from truenas scale to a project. but I'm having trouble doing so. I wanted to export it as a raw file. Does anyone know how?

dd if=/dev/zvol/pool/zvol_name of=/path/to/file.raw seems like it ought to do the trick.

You can also use qemu-img if you want to convert it to another image type.

Awesome! Thanks!!

So I tried that and I keep getting this error:

dd: writing to 'VMDrive.raw': No space left on device

I have 128gb of Memory and 1.5tb of space. more than enough. but this is the error I keep getting.

How big is the zvol and what format do you want the output in? Sample command (not tested) qemu-img -o qcow2 /dev/zvol/tank/somezvol somefile.qcow2, not sure what you are trying to get out of it.

What did you pick for /path/to/file.raw? Is there enough space in that exact location?

The ZVOL is 120gb Volume, and i have one that's 256gb Volume.

same folder, but it has more than enough room

What do you mean by "same folder"? if there is enough room, you don't get a "no space left on device" error. Plain and simple.
