|Today I ran into a VMware problem. When using shared virtual disks between two (or more) VM's and you want to increase the size of a shared disk, the VM's will not boot anymore. You get an error message which starts like this:
Vmware ESX server cannot open the virtual disk "vmfs/volumes/.../vm1/vm1_2.vmdk" for clustering
I made a workaround to solve that problem. You will find that in the Howto: Error on boot of VM: ESX server cannot open the virtual disk for clustering.
