Hi,

It's possible to change a thin-provision disk to a preallocated disk?

Storages are ISCSI

Thanks

there was an old thread about it at the time of 4.0/4.1. What it worked and I verified still works in 4.5 is: VM is powered on or off (with pros and cons for both scenarios in case of production machine) create a snapshot of the VM select the snapshot line under snapshots and select clone button in resource allocation section of the new vm screen change allocation policy for the desired disk/s from thin provision to preallocated Then you can decommission old VM and use the cloned one HIH, Gianluca
