Gluster users - Apr 2014 - IP failover in QEMU-Glusterfs native integration using libgfapi?

Dear All,

I am using QEMU 1.7.0 and GlusterFs 4.3.2 and have carried out necessary 
configurations to enable QEMU-Glusterfs native integration (i.e., using 
libgfapi instead of FUSE).

On the server side, I have configured a volume named "image" using two
bricks on two different machines "brk1" and "brk2". And a
qcow2 image
*centos.qcow2* has been imported to Glusterfs.

On the client side (e.g., the KVM host), the configuration "-drive 
file=gluster://*brk1*/image/centos.qcow2" is used when starting a KVM 
VM. The VM boots successfully.
When it's running, I shut down the machine brk1 on purpose and want to 
see whether the KVM VM can automatically switch to use "-drive 
file=gluster://*brk2*/image/centos.qcow2" (i.e., IP failover). 
Unfortunately, the VM crashes.

I am writing to ask whether the feature "IP failover" in
QEMU-Glusterfs
native integration is supported. Thanks so much for your kind help!


Best Regards,
Bob ZHANG

Hi,

I am trying to achieve the same thing.   Why did you have to enable QEMU 
native integration when Glusterfs 4.3.2 already has native QEMU support?

How did you import the qcow2 image and how did you set it up.


Thanks,

Dan
