Our QA department found a moderate issue this morning. It appears out server build automation software didn't quite work properly with the partitioning info we gave it, and failed back to an antiquated standard build (8GB /, 10GB /var, 8GB /opt, and 4gb swap). The disk is a 300GB raid 10, which should be fully utiized. So, I am trying to scale everything out in a sane way. Extending swap was easy, and it was extended to 24GB. I want to extend /var to 20GB, and /opt to 10GB (no additional software is being installed, these are logging servers). Then / must be extended to use the remaining disk space.
So, the heart of my question - is this something that can be done online? Or do I have to log into ash and do it from there? I know that ext3 (supposedly) supports hot online resizing, but I don't know about lvm2. Any advice would be appreciated. Thanks!
Edit: I will have OOB access to these servers shortly, I was just hoping not to have to have our already overworked QA department run a bunch of cabling to get it for me if I don't have to.
