Re: root low space
The only problem I still have is to first backup home and root on another computer along my network. Obvious as it might be to most users, I found that dd if=/dev/vg1/root | ssh 192.168.#.## dd of=/home/chiendarret/tmp/vg1-root works fine with SystemRescueCD within my LAN. It is (also obviously) liable to file compression. francesco On Mon, May 26, 2014 at 8:04 AM, Francesco Pietra chiendar...@gmail.com wrote: I forgot to add that, either from the linux console, or a terminal from startx, fdisk -l shows correctly /dev/md0 /dev/md1, both with their /dev/mapper/vg1-root and all other /mapper/vg1 Also, all needed codes , resize2f lvreduce lvexternal are on the path.

Hi Francesco, backup only the affected volumes (2 in your case, being vg1-root and vg1-home).

If not, resize vg1-home (reduce size) and afterwards increase vg1-root. But be careful first resize the filesystem (resize2fs) and afterwards the logical volume (lvreduce), otherwise you might loose data.

Re: root low space
Hi Fransesco, what does 'vgs' say is there free space? If not, resize vg1-home (reduce size) and afterwards increase vg1-root. But be careful first resize the filesystem (resize2fs) and afterwards the logical volume (lvreduce), otherwise you might loose data.
