Not enough disk space in filesystem for VM image
Hi
I created a 10Gig VM image with virt-install, then used OpenStack Dashboard>Project>Compute>Images>CreateImage to add this image to my Images list.
While the image was uploading, I noticed that my Filesystem /dev/mapper/centos-root usage goes from 57% to 100%
[root@controller-node]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/centos-root 50G 29G 22G 57% /
devtmpfs 32G 0 32G 0% /dev
tmpfs 32G 180K 32G 1% /dev/shm
tmpfs 32G 1.2G 31G 4% /run
tmpfs 32G 0 32G 0% /sys/fs/cgroup
/dev/mapper/centos-home 848G 9.8G 838G 2% /home
Then the VM image failed to complete the uploading process. The OpenStack Dashboard showed the image as "Killed". So I guess my /dev/mapper/centos-root partition is too small. I am assuming that the VM image was created on this partition. So my question is: is there anyway to create the VM image on the other partition /dev/mapper/centos-home which has plenty of room ?
Thank you for your help
