I've installed Fedora's root (/), boot and swap folders on my SSD (sdb). Now I want to decrease root's size and change swap to my HDD (sda), but system-config-lvm won't let me do it. Why? What am I doing wrong? Also, how do I change swap to my HDD?
Thanks.
To decrease size of a partition, you need that partition to be unmounted. Therefore, to decrease the size of / partition you need to boot your system with either a live media or installation disk (using system-config-lvm needs a live media). Also, I don't remember if system-config-lvm will also resize file-systems (in addition to logical partitions). If not, you MUST shrink your / filesystem before resizing / logical partition.
Resizing a filesystem is potentially destructive, make sure you have good backups. Creating backups is also something you should do before updating to a newer release of Fedora - since system-config-lvm isn't available in the latest Fedora, I'm guessing that's something @r00t should do too.
If system-config-lvm was not available, or if using installation disk to do the resize (which doesn't include system-config-lvm), @r00t should use lvreduce from command line. It is answered somewhere else in Ask Fedora with some details about resizing filesystem and LVM logical disk separately using command line.
What if we create live usb bootable with gparted? Will it decrease LVM partition there?
