Provisioned and Total disk space

[andvm]

Hi,

Is there any command that can be run against a datastore (not limited to vSAN) to find out the total space provisioned and free space?

This would be extremely useful when having a mix of VMs (think/thick).

Thanks

Hello andvm​,

# df -h

which column shows the provisioned total please? (I can have 234.5GB free left but that does not mean its not over provisioned)

[root@localhost:~] df -h

Hello andvm​,

Provisioned would be 'Used' - whether this space has all been reserved or is in use depends on the max disk size, data used in-guest and Thin/Thickness of the disks (OSR=0 or OSR=100), e.g. .vswp Objects will be Thick by default, .vmdk (and their snapshots) Thin if using Default vSAN Storage Policy or any without Object Space Reservation = 100.

You can see Thick/thin proportion of data better via RVC with vsan.disk_stats <PathToCluster/Host>  (Reserved column)

Ok Bob, in meantime I found the below which seems to print nicely what I need:
