Deallocate some extents on encrypted root device in order to increase free physvolume
I just install Debian 8.1. I allocated for lvm volume group almost all disk (300 GiB ) to encrypted partition and a little bit for boot. I want to make smaller 50GiB encrypted physical volume and install different xen OS to the free space.
Is it possible to do it without data loss? How? ============ System info: /dev/dm-1 ext4 / /dev/sda1 ext2 /boot Files in /dev/mapper : control hostname--vg-root hostname--vg-swap_1 sda5_crypt |
I think I used this Ubuntu how-to when I wanted to test this recently.
I think I used gparted to do the partition resizing rather than fdisk. I did this on a system I could afford to lose, but everything went fine. |
