Hello,
I am deploying linked clone desktops for Viewplanner 3.0.1 tests and I have issues, which are related to view and linked clones.
Linked clone pool is automated pool with floating assignment.
Golden image needs to have two disks, first is 16GB disk which is system C: drive and second one is 1GB disk (drive E:) which holds test data.
Issues that I am experiencing are either:
1) when I set data disk as independent, it is not cloned and added to the linked clone VMs
2) when I set data disk as dependent then it is added to the linked clone VMs, but it is also a linked clone which causes following error "Error: Heap seSparse could not be grown by 12288 bytes for allocation of 12288 bytes" if you have more than 100 VMs per host.
I suspect that this is related to the following known issue
After you upgrade to vSphere 5.5, a heap size error can occur if you use space-efficient virtual disks and you have more than 200 linked-clone virtual machines per ESXi host. For example: Error: Heap seSparse could not be grown by 12288 bytes for allocation of 12288 bytes
Workaround: Reduce the number of linked-clone virtual machines that use space-efficient virtual disks to less than 200 per ESXi host.
I think that since your VM has 2 linked clone disk (system disk C: and data disk E:) that it actually count as 2 linked clone VMs each with single disk. So instead of 200 linked clone VMs you are limited to just 100.
Virtual hardware of the Goldenimage is vmx-09 and I didn't set up anything regarding seSparse disks at least not that I would know.
Is there any way to create linked clone pool with floating assignment and that each VM would have full copy of additional data disk ?
Best regards
