LVM

df -h shows filesystem information

Also helpful: system-config-lvm ¹⁾

Remember to look for e.g. samba shares of regarding drives before changing the partition layout. I had a share pointing to a windows drive, which will be vaporized.

Adding free disc space to lvm:

1. Delete useless windows partition (don't forget to backup data!) in case there is no free disc space
2. use cfdisk /dev/hdb to create a partition, the type has to be 8e to mark it as LVM controlled
3. umount /dev/hdb1 (assuming you are dealing with hdb1)
4. pvcreate /dev/hdb1 → now there is a physical volume
5. vgextend lvm_vg1 /dev/hdb1 → extend volume group named lvm_vg1 to physical device /dev/hdb1
6. pvmove /dev/hda4 /dev/hdb1 → move contents of /dev/hda4 to /dev/hdb1
7. Entferne Datenträger aus Datenträgergruppe - using system-config-lvm tool
8. pvremove /dev/hda4
