Hi all, I hoped I could follow up with my post from libvirt-users, and include the details in hopes someone can help. I have an fc18 system and trying to resize an LVM partition with an ext4 filesystem and receiving the following message from virt-resize: # virt-resize -d --expand /dev/sda1 --LV-expand /dev/mapper/prop-home prop-1.img prop-expand.img command line: virt-resize -d --expand /dev/sda1 --LV-expand /dev/mapper/prop-home prop-1.img prop-expand.img Examining prop-1.img ... libguestfs: trace: add_drive "prop-1.img" "readonly:true" libguestfs: trace: add_drive = 0 libguestfs: trace: add_drive "prop-expand.img" "readonly:false" libguestfs: trace: add_drive = 0 libguestfs: trace: launch libguestfs: trace: get_tmpdir libguestfs: trace: get_tmpdir = "/tmp" libguestfs: trace: get_cachedir libguestfs: trace: get_cachedir = "/var/tmp" libguestfs: trace: disk_format "/var/lib/libvirt/images/prop-expand.img" libguestfs: trace: disk_format = "raw" libguestfs: trace: get_cachedir libguestfs: trace: get_cachedir = "/var/tmp" [...] 100% --:-- libguestfs: trace: launch = 0 libguestfs: trace: lvm_set_filter "/dev/sda" libguestfs: trace: lvm_set_filter = -1 (error) Fatal error: exception Guestfs.Error("lvm_set_filter: vgchange: Couldn't find device with uuid zouQ8X-qxqJ-mp6p-pzg3-mi2i-K9YM-A763Kc. Refusing activation of partial LV home. Use --partial to override. Refusing activation of partial LV swap. Use --partial to override. R libguestfs: trace: close libguestfs: trace: internal_autosync libguestfs: trace: internal_autosync = 0 I don't understand this error message. I also see that vgchange doesn't even have a 'partial' option, so I'm not sure how to troubleshoot it. Here is the filesystem layout for this system: # df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 7.9G 0 7.9G 0% /dev tmpfs 7.9G 0 7.9G 0% /dev/shm tmpfs 7.9G 3.9M 7.9G 1% /run tmpfs 7.9G 0 7.9G 0% /sys/fs/cgroup /dev/mapper/prop-root 15G 7.4G 6.3G 55% / tmpfs 7.9G 0 7.9G 0% /tmp /dev/mapper/prop-boot 477M 95M 358M 21% /boot /dev/mapper/prop-home 222G 212G 9.9G 96% /home The image is the 222G /home partition only. The other partitions are on another image. There are a bunch of links regarding other methods for resizing an LVM from within a VM. I don't know which to follow. Can someone make a recommendation of one they know works with current systems? Any ideas how to troubleshoot this would be greatly appreciated. Thanks, Alex
