Useful “How to” from Pivotal.io – Increase root partition size VMware
Running out of room on your root VCSA (VMware Vcenter Appliance) VM? Virtual center update’s failing? One of the things I’ve noticed is – as your supplying the ISO to your VCenter to perform an update – the first thing the UI does is copy the ISO to the root folder. If your tight on space you make have an issue, or the update may fail. My new rule of thumb is, if you don’t have 4GB of space free on root, you need to extend. Check this out.. Good walk through:
