Hi, I'm trying to resize a 15GB LVM root partition on a fedora20 server with a fedora20 guest and I'm having a problem. Is this supported on fedora20? I recall having a similar problem (maybe even exact same problem) all the way back in fedora16 or fedora17, but hoped/thought it would be fixed by now? # virt-df -h test1-011015.img Filesystem Size Used Available Use% test1-011015.img:/dev/prop/boot 476M 109M 338M 23% test1-011015.img:/dev/prop/root 14G 10G 3.3G 72% # truncate -s 50G newimg # virt-resize test1-011015.img newimg --expand /dev/sda1 --LV-expand /dev/prop/root Examining test1-011015.img ... virt-resize: libguestfs error: lvm_set_filter: vgchange -ay: /run/lvm/lvmetad.socket: connect failed: No such file or directory WARNING: Failed to connect to lvmetad: No such file or directory.

Seems like you won't be able to use pure vgchange and do thing by hand anyway. Michal

Is that even possible? Thanks, Alex> > Michal
