Expand LVM guest filesystem VMware
December 30, 2009 – 12:07 am by Hannes Van de VelFirst, increase the size of the virtual disk (VMDK) by 10GB for example
vmware-vdiskmanager -x 10GB /path/machineName.vmdk
(vCenter users can increase disk sizes easier via the Settings dialog of the VM)
# fdisk /dev/sda n Command action e extended p primary partition (1-4) p Partition nr 3
Take defaults as from here
First cylinder (1045-2610, default 1045): Using default value 1045 Last cylinder or +size or +sizeM or +sizeK (1045-2610, default 2610): Using default value 2610
Change a partition’s system id

Partition number (1-4): 3 Hex code (type L to list codes): 8e Changed system type of partition 3 to 8e (Linux LVM)
