What would be the best course of action to switch my system to lvm? This is what I have:
Filesystem Size Used Avail Use% Mounted on rootfs 9.2G 8.3G 425M 96% / udev 10M 0 10M 0% /dev tmpfs 592M 756K 591M 1% /run /dev/disk/by-uuid/b9a3a0e3-9f3b-401e-8f12-8d123e6e7f3b 9.2G 8.3G 425M 96% / tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 1.5G 536K 1.5G 1% /run/shm /dev/sda7 29G 5.6G 22G 21% /home Plus mount -l sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime) proc on /proc type proc (rw,nosuid,nodev,noexec,relatime) udev on /dev type devtmpfs (rw,relatime,size=10240k,nr_inodes=755582,mode=755) devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000) tmpfs on /run type tmpfs (rw,nosuid,noexec,relatime,size=605680k,mode=755) /dev/disk/by-uuid/b9a3a0e3-9f3b-401e-8f12-8d123e6e7f3b on / type ext4 (rw,relatime,errors=remount-ro,user_xattr,barrier=1,data=ordered) tmpfs on /run/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,size=5120k) tmpfs on /run/shm type tmpfs (rw,nosuid,nodev,noexec,relatime,size=1474720k) /dev/sda7 on /home type ext4 (rw,relatime,user_xattr,barrier=1,data=ordered) rpc_pipefs on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw,relatime) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,nosuid,nodev,noexec,relatime) fusectl on /sys/fs/fuse/connections type fusectl (rw,relatime) And there is also 600 GB of adjacent disk space where /home used to be from squeeze. I already made a tarball with these older /home and saved it to an exterior device. I want to reuse this disk space, with lvm, and migrate existing wheezy installation to it, occupying the whole disk this time and bringing back most of the old data saved in the tarball. Any comments on best way and steps to accomplish this? Thanks.
