When creating a virtual disk for your Vm you will carve a virtual disk file (VMDK) that will be equal to the size of the disk you create - so creating a virtual disk of 40GB will create a VMDK file that is 40 GB in size. create a 1TB ZFS partition using 4 physical volumes)ģ) I'm assuming that even though I created a VM under ESXi for OpenSolaris to use only 40GB it is actually reading the physical volume and using 140GB - am I correct or am I wrong? I guess as someone new to ESXi my questions are:ġ) If the disks are formatted under VMFS, wouldn't a file-system like Solaris' or OpenSolaris' ZFS be obsolete?Ģ) If you wanted to create a pool of disks in ZFS, would that be possible considering you're using physical volumes formatted under VMFS? (i.e. (combined, they all total about 140GB which is the remaining space of my datastore1) For more information, see Performing a rescan of the storage on an ESX/ESXi host (1003988). I installed OpenSolaris and noticed that I have a few partitions of 22GB each. To create a new VMFS volume from the ESX/ESXi host command line: Rescan the storage subsystem to ensure that the host is updated with the latest storage information. (The total available space on datastore1 is around 140GB (other VMs take up the rest)). I created a new VM and gave it 40GB of a 250GB datastore (known as datastore1 in ESXi). VMFS is used to store the virtual machine disk image, snapshots.

Featured Sponsor VMFS is designed & optimized file system for the optimum performance of the virtual machines in virtual environment. I bring this up because of something odd that I noticed in a version of OpenSolaris on ESXi. VMFS is a high-performance clustered file system used by the VMware vSphere.
