So it turns out this was even easier than I expected. The home partition was actually built upon LVM so some relatively simple use of LVM allowed me to do exactly what I wanted. However I have some very subtle issue that I don't understand. virt-manager, df and du incorrectly think this: > df Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/centos_mric--srv2-root 52403200 5717192 46686008 11% / devtmpfs 16378220 0 16378220 0% /dev tmpfs 16388924 88 16388836 1% /dev/shm tmpfs 16388924 9224 16379700 1% /run tmpfs 16388924 0 16388924 0% /sys/fs/cgroup /dev/mapper/centos_mric--srv2-home 433378560 32928 433345632 1% /home /dev/sda1 508588 219764 288824 44% /boot /dev/mapper/centos_mric--srv2-vm--images 67858700 16294864 51563836 25% /vm-images > du -k /vm-images 16261904 /vm-images But ls has it correct: > ls -alt /vm-images total 16261908 -rw-------. 1 qemu qemu 51547734016 May 9 15:15 centos7.0-1.qcow2 -rw-------. 1 qemu qemu 12887130112 May 9 15:15 centos7.0.qcow2 drwxr-xr-x. 21 root root 4096 May 9 15:13 .. drwxr-xr-x. 2 root root 52 May 9 13:39 . Any idea how I make this correct? There are no side effects that I see but it is extremely puzzling to me as to why the new partition does not have the correct size. It appears the larger of the two VM images is not getting counted. -- Paul (ganci at nurdog.com) (303)257-5208
