That would be quicker to get started though. :) @latoga: while that is easier, that micro cloud deployment isn’t built on ubuntu 11.10. That would be quicker to get started though. :)

It's a preconfigured VM (1 GB RAM/8 GB Disk) with entire Cloud Foundry supported tools already installed.

]]> Comment on LVM and vmware linux guests. Just do it already. by nate http://conrey.org/2011/05/18/lvm-and-vmware-linux-guests-just-do-it/#comment-37 nate Thu, 19 May 2011 04:08:54 +0000 http://www.conrey.org/?p=1329#comment-37 good article! I for one have always used LVM on linux, but typically only on RDM volumes (e.g. databases - I use RDM so I can use SAN-based snapshots). One thing to keep in mind when using LVM in vmware, last I checked the vmware tools were unable to shrink the volume from inside the guest. For me, my standard is 10GB for linux installs, a full OS deploy takes about 2.3GB (basically everything and the kitchen sink for a server), 512MB of swap, Logs might take another gig or two at the most for most systems. Anything beyond that I always add another disk on an as-needed basis, and usually use LVM on them unless I'm really sure I won't need to expand it in the future(rare but it happens). Then I have a HA NFS cluster (commercial appliance-based not homemade) for other file needs(e.g. log archiving etc). Only in the most rare cases did disk usage on the average system exceed say 5GB (across ~300 VMs). Combine that strategy with thin provisioning..... I've never had an issue resizing a file system online at least with RHEL 5 kernels and up, older kernels the driver didn't support it (it would just error out saying to unmount the file system). Note that online resize is a very I/O intensive operation so if your system is sensitive to latency you should run it off peak hours, Every time I have seen it it has pegged the I/O while the resize is running. I first started using LVM in ESX as an easy way to identify volumes that were being imported into the system over iSCSI (directly to the guest, not through the hypervisor). I have quite a few scripts that do all sorts of snapshots, full volume cloning etc through the SAN and copy volumes around to different physical and virtual machines for various purposes (usually involves databases). sample output from such a process: http://yehat.aphroland.org/~aphro/san/mysql-backup-prod-backup-2_20080319_070501.log good article!
