Creating the VMDK files
The VMDKs that will be used by Storage Foundation Cluster File System High Availability (SFCFSHA) can be created either by the vSphere GUI or using the command line. Using the GUI, there is no control for the name of the file used, and they will be stored under the folder belonging to the VM that is creating the files. We would prefer in this case to control those file names, so we will use the command line to create the following configuration:
Table: Virtual disk configuration
Data Store | Virtual Disk on ESXi | VMDK NAME | Virtual device | SCSI Driver | Virtual size (GB) |
---|---|---|---|---|---|
DS1 | Hard disk 2 | cfs0/shared1.vmdk | SCSI 1:0 | Paravirtual | 90 |
DS2 | Hard disk 3 | cfs0/shared2.vmdk | SCSI 1:1 | Paravirtual | 90 |
DS3 | Hard disk 4 | cfs0/shared3.vmdk | SCSI 1:2 | Paravirtual | 90 |
DS4 | Hard disk 5 | cfs0/shared4.vmdk | SCSI 1:3 | Paravirtual | 90 |
DS5 | Hard disk 6 | cfs0/shared5.vmdk | SCSI 1:4 | Paravirtual | 90 |
To create the infrastructure
- Connect to one of the ESXi virtual machines.
- Create a folder called cfs0 (the name of the cluster) in each of the datastores:
mkdir /vmfs/volumes/DS1/cfs0 mkdir /vmfs/volumes/DS2/cfs0 mkdir /vmfs/volumes/DS3/cfs0 mkdir /vmfs/volumes/DS4/cfs0 mkdir /vmfs/volumes/DS5/cfs0
- Create each of the VMDKs that will be used:
vmkfstools -c 90G -d eagerzeroedthick /vmfs/volumes/DS1/cfs0/shared1.vmdk vmkfstools -c 90G -d eagerzeroedthick /vmfs/volumes/DS2/cfs0/shared2.vmdk vmkfstools -c 90G -d eagerzeroedthick /vmfs/volumes/DS3/cfs0/shared3.vmdk vmkfstools -c 90G -d eagerzeroedthick /vmfs/volumes/DS4/cfs0/shared4.vmdk vmkfstools -c 90G -d eagerzeroedthick /vmfs/volumes/DS5/cfs0/shared5.vmdk
