vmkfstools --growfs returning Error: No such file or directory

Hi all,

i am trying to grow a datastore. I follwed this guide:  VMware KB:    Growing a local datastore from the command line in vSphere ESXi 4.x and 5.x

Everything went fine up to the last step. I checked after and the end sector had been correctly changed for the datastore partition. Also verified the partition was at the end of the table with the free space after it.

When I try the last command "vmkfstools --growfs" it always comes back with "Error No such file or directory":

vmkfstools --growfs "/vmfs/devices/disks/t10.ATA_____Samsung_SSD_850_EVO_500GB_______________S21JNX

AG598701W_____:3" "/vmfs/devices/disks/t10.ATA_____Samsung_SSD_850_EVO_500GB_______________S21JNXAG598701W_____:3"

Not found

Error: No such file or directory

Any ideas?

Thanks,

Toni
