All VM's in the NY100 datacenter were created with Thick provisioning. This is beginning to cause space issues, mainly on cresskill, where the Uber VM is providing virtual shared storage for the Towers Cluster. The conversion from Thick to thin can be performed by "Storage vMotion", as one of the option in the wizard is to change the disk provisioning. Cloning would also work.
The clone function was tried first, on Uber2 (iSCSI test Ubuntu). Once cloned, one of the NIC cards would not load properly in Ubuntu, even though both cards were present in the VM's settings. After some of the following commands, the 2nd NIC was up:
modprobe
lshw -C network (showed 1 NIC disabled)
iwconfig (showed the actual selected "eth" numbers for the NICs)
Once the correct eth number was placed in /etc/network/interfaces, Uber2 was back in business.
The storage vMotion method was used going forward.
Cold vMotion of VCS01, red-bank, and Trenton into the Towers1 cluster will be needed in order to allow enough space for Uber to be migrated, since Uber has a 200GB partition for shared storage.
