Problem
Filesystem in LVM is full.
Solution
Obtain more disk (physical, virtual, whatever). Install in VM/system.
Use fdisk to partition the new disk (assumed to be sdb in this example). Set the new partition to be of type 8e.
Create a new PV on the new disk partition:
List your volume group:
# vgdisplay
--- Volume group ---
VG Name Volume00
System ID
Format lvm2
[...]
Add the new PV into the volume group:
# vgextend Volume00 /dev/sdb1
List your logical volumes:
# lvdisplay
--- Logical volume ---
LV Path /dev/Volume00/lvroot
LV Name lvroot
VG Name Volume00
[...]
Grow the logical volume that is full:
# lvextend /dev/Volume00/lvroot /dev/sdb1
Resize the filesystem into the new volume size:
# resize2fs /dev/Volume00/lvroot
Done!
