SMB3 mounted on linux / Debian - qemu-img Failed to get "resize" lock

  • 772

I have a Windows 2016 SMB share mounted on a Debian 10 box. I am using qemu-img to convert an image file the target of which I wish to store on the SMB mount. When I run the command I get this error:

error while converting qcow2: Failed to get "resize" lock

This suggests that either qemu-img is misinterpreting the lock on the mount or that there is something incorrect with the mount itself. I note that qemu-img does not seem to support stdout, which is extremely frustrating!

Are there any tunables I can use to bypass this error?

Thanks!

windows linux debian smbclient

  1. Try downgrading / re-negotiating to SMB 2.xx dialect. There are some issues with 3.xx still.
