Well, I think this is one of the big examples of what we can do with LVM: http://www.greyoak.com/lvmdrive.html
This is one of the top reasons that I use LVM on my home builds. I generally build with an SSD as the OS disk and a large SATA drive as my /home. When I need a bigger disk, which happens occasionally, I can either add or move up to a larger disk. I tend to just move up to a larger disk as I prefer a single disk to multiple disks for both reliability, reduced noise, and reduced power usage. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
So we can generally say that LVM offers no real drawbacks in terms of flexibility, but it seems like we are mostly talking about homebrew setups.
What about in a high iops situation? Is there any evidence/testing out there that might show that there is some overhead of LVM that might impact total throughput?
