[libvirt-users] Resizing ext4 fedora qemu guest

Hi, I have a fedora14 host with a fedora15 guest and I'm trying to resize the /home partition from 200GB to 240GB. I'm relatively new to the virsh/guestfish commands, as well as LVM, although I think I have a reasonable understanding. I have followed the virt-resize directions (http://libguestfs.org/virt-resize.1.html), but it still shows 200GB: # fdisk -l /dev/mapper/vg_custserv-lv_home Disk /dev/mapper/vg_custserv-lv_home: 197.2 GB, 197165842432 bytes 255 heads, 63 sectors/track, 23970 cylinders, total 385089536 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Outside of the guest, I see this: # virt-filesystems --long --parts --lvs -h -a newdisk.img Name Type Size Parent /dev/vg_custserv/lv_home lv 184G /dev/vg_custserv /dev/vg_custserv/lv_root lv 50G /dev/vg_custserv /dev/vg_custserv/lv_swap lv 5.9G /dev/vg_custserv /dev/sda1 partition 500M /dev/sda /dev/sda2 partition 240G /dev/sda The partition is the correct size, but it appears the volume group(?) is not the correct size. fdisk from within the guest also shows the correct size for the device. I've tried resize2fs from within the guest. Does virt-resize understand the ext4 filesystem and how to properly resize it? Is that my problem? I've also tried using guestfish with lvresize-free without success: <fs> lvresize-free /dev/mapper/vg_custserv-lv_home 100 libguestfs: error: lvresize_free: New size (5876 extents) matches existing size (5876 extents) Run `lvresize --help' for more information. I'm really not sure what to do next. Any ideas greatly appreciated. Thanks, Alex
