vmkfstools - Extension of a Clustered (shared) VMDK
Implementation plan
1.Disable monitoring
2.Stop Applicationon servers if needed.
3.Disable DRS on Vmware cluster ( To avoid any migration )
4.Shutdown servers f.e ( server1 , server2, server3, server4_disk_owner )
5.Clone server4_disk_owner before disx extention.
6.SSH to esx related with vm's
7.Run command vmkfstools --extendvirtualdisk 2048G /vmfs/volumes/5adyya766-e21d5177-4kdb-7cd30ae2b398/server4_disk_owner/server4_disk_owner.vmdk -d eagerzeroedthick
8.Start vm's in oposite order (server4_disk_owner, server3, server2, server1 )
9.Edit disk to check if new space was alocate to 2048G
10.Login to server server4_disk_owner and extend disk on OS level using dispart (for Windows only :)
Command:
-diskpart
-list disk
-select disk
-list volume
-select volume
-extend
10.Start application on servers if needed.
