This week suddenly two virtual machines on our shop stopped because of to little space on the hosts storage. This is because we didn't think of the extra amount of storage that is required when using snapshots on a Exchange server on this host. The host storage is 270GB. Only 200GB is predefined by the virtual machines, but snapshot files are living there own life's besides and are now nearly reaching 70GB,
Can we safely delete all snapshot's from the snapshot manager in ESXi 4.0, and is it correct that data on the snapshot files will be merged with the "original" storage upon deletions?
