[libvirt-users] failure creating a snapshot volume within a lvm-based pool
Hi I have defined a logical pool and a volume within it # virsh vol-create-as images_lvm myvol 2G Vol myvol created # virsh vol-list images_lvm Name Path ----------------------------------------- myvol /dev/libvirt_images_vg/myvol if I try to create another volume using the previous one as backing-vol, the creation fails with what looks like an incorrect commandline for lvcreate: # virsh vol-create-as images_lvm myvol-instance 2G --backing-vol myvol error: Failed to create vol myvol-instance error: internal error Child process (/usr/sbin/lvcreate --name myvol-instance -L 2097152K -s=/dev/libvirt_images_vg/myvol) unexpected exit status 3: /usr/sbin/lvcreate: invalid option -- '=' Error during parsing of command line. Exactly the same happens if I specify a qcow2 format (the doc however says that The logical volume pool does not use the volume format type element). is this a known bug? I'm running Fedora 18 # virsh version Compiled against library: libvirt 0.10.2 Using library: libvirt 0.10.2 Using API: QEMU 0.10.2 Running hypervisor: QEMU 1.2.2 -------------------------------------------------- regards, Edoardo Comar WebSphere Application Service Platform for Networks (ASPN) ecomar@uk.ibm.com Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.

Hi,
if I try to create another volume using the previous one as backing-vol, the creation fails with what looks like an incorrect commandline for lvcreate:
# virsh vol-create-as images_lvm myvol-instance 2G --backing-vol myvol error: Failed to create vol myvol-instance error: internal error Child process (/usr/sbin/lvcreate --name myvol-instance -L 2097152K -s=/dev/libvirt_images_vg/myvol) unexpected exit status 3: /usr/sbin/lvcreate: invalid option -- '=' Error during parsing of command line.
this has been fixed in 1.0.2 by commit ffee627a: http://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=ffee627a

Yes, volume format has no effect on logical pools. Jan
Thanks I have opened https://bugzilla.redhat.com/show_bug.cgi?id=955371 as would be nice to get the fix in the packages of the distro -------------------------------------------------- regards, Edoardo Comar WebSphere Application Service Platform for Networks (ASPN) From: Ján Tomko <jtomko@redhat.com> To: Edoardo Comar/UK/IBM@IBMGB, Cc: libvirt-users@redhat.com Date: 22/04/2013 19:02 Subject: Re: [libvirt-users] failure creating a snapshot volume within a lvm-based pool On 04/22/2013 07:40 PM, Edoardo Comar wrote:
