Description
-------
By default all network disks are in RAW format. Gluster works fine with
QCOW2 which has some advantages.
Disks are by default in QCOW2 format. It is possible to run into
a mismatch, where the disk is in QCOW2 format, but QEMU gets started
with format=raw. This causes the virtual machines to lockup on boot.
Failures to start a virtual machine can be verified by checking the log
of the virtual machine, and compare the output of 'qemu-img info'.
In /var/log/libvirt/qemu/<VM>.log find the URL for the drive:
-drive file=gluster+tcp://...,format=raw,..
Compare this with the 'qemu-img info' output of the same file, mounted
under /mnt/<pool-uuid>/<img-uuid>:
# qemu-img info /mnt/<pool-uuid>/<img-uuid>
...
file format: qcow2
...
This change makes passes the format when creating a disk located on RBD
(RAW only) and Gluster (QCOW2).
