Re: [PATCH] fix source name attribute for gluster volumes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

I got this error when i made few subdirectories in gluster volume, and changed <dir path /> in  libvirt pool xml accordingly.
Here is command line and debug output in attached file:
 python /usr/share/virt-manager/virt-install  --name=vm3vv --disk vol=gluster-pool/vm3vv.qcow2,bus=ide,cache=none --ram=1024 --vcpus=1 --cdrom=/var/glusterfs/vm_images_and_config/iso/msvs3_12.2.iso --debug --network=bridge:br0,model=virtio --noautoconsole >> virtinstall.log 2>&1

gluster-pool.xml is pool definition from /etc/libvirt/storage

Thanks for the patch. Can you describe how to reproduce this issue? If via
virt-install, please provide the full command line and debug output, since I'd
like to add a test case that covers this

Thanks,
Cole
