[Bug 1554451] Re: unable to create preallocated image with gluster network protocol

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to another 
system. For this we need to know which bugs are still valid and which could be 
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state 
back to "New" within the next 60 days, otherwise this report will be marked as 
"Expired". Or mark it as "Fix Released" if the problem has been solved with a 
newer version of QEMU already. Thank you and sorry for the inconvenience.

Title:
  unable to create preallocated image with gluster network protocol

Status in QEMU:
  Incomplete

Bug description:
  Unable to create preallocated image with gluster protocol

  Version: qemu-img-0.12.1.2-2.479.el6.x86_64
  Platform: RHEL 6
  I have tried creating preallocated image as follows :

  qemu-img create -f qcow2 -o preallocation=full
  gluster://localhost/vol1/vm1.img 10G

  I see error a follows :
  [root@ ]# qemu-img create -f qcow2 -o preallocation=full 
gluster://localhost/rep3vol/vm1.img 5G
  Formatting 'gluster://dhcp37-61.lab.eng.blr.redhat.com/rep3vol/newvm3.img', 
fmt=qcow2 size=3221225472 encryption=off cluster_size=65536 preallocation='full'
  Unknown option 'preallocation'

  I could inspect the image using qemu-img info, but still its not
  preallocated,

  [root@ ]# qemu-img info newvm3.img 
  image: newvm3.img
  file format: qcow2
  virtual size: 3.0G (3221225472 bytes)
  disk size: 588K
  cluster_size: 65536
