Hi Guys,
I have a Fedora 21 machine on which I configured the 250Gb drive in the
following way:
hobgoblin:~:{619}lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 232.9G 0 disk
├─sda1 8:1 0 500M 0 part /boot
└─sda2 8:2 0 232.4G 0 part
├─fedora-swap 253:0 0 15.7G 0 lvm [SWAP]
├─fedora-root 253:1 0 50G 0 lvm /
└─fedora-home 253:2 0 166.7G 0 lvm /home
sr0 11:0 1 1024M 0 rom
sr1 11:1 1 1024M 0 rom
hobgoblin:~:{620}df
Filesystem Size Used Avail Use% Mounted on
devtmpfs 16G 0 16G 0% /dev
tmpfs 16G 122M 16G 1% /dev/shm
tmpfs 16G 1.5M 16G 1% /run
tmpfs 16G 0 16G 0% /sys/fs/cgroup
/dev/mapper/fedora-root 50G 38G 9.5G 80% /
tmpfs 16G 460K 16G 1% /tmp
/dev/sda1 477M 177M 271M 40% /boot
/dev/mapper/fedora-home 164G 11G 146G 7% /home
tmpfs 3.2G 28K 3.2G 1% /run/user/2155
I've been using the machine for over a year, and all's well, except that
I'm now continually running out of space on the / volume. The applications
I use install in /opt, and I have to keep many different versions around
for my work, so space is getting very tight. /home has plenty of space
though, so I'd like to reallocate most of it to /.
I've used the OSX disk utility to "pack" a partition's contents into it
more efficiently, and then reduce the size of the partition so I can
reallocate it to another. Using that gui tool, the process is all very
clear and works great.
When I set up the Fedora 21 machine, there was a very nice gui interface
for setting up the partitions and logical volumes. But Fedora 21 doesn't
seem to have an equivalent tool that can be run after installation, now
that system-config-lvm is no longer supported. Command-line lvm looks
simple-ish to use; but what I'm not clear on is whether it can pack a
volume's contents in order to create a clear area of unused space before
resizing the volume.
I can't afford to break this machine, so I'm trying to make sure I know
exactly what I'm doing before I get started.
Thanks, mitch
