In general running a single os with lvm (ie: 1: boot partition, 2: LVM then put /, swap and maybe /home in the LVM) is fine and quite a few people like it.
I'm still like just putting it straight on the disk (ie: 1 boot (or root), 2: swap, 3:/ 4:/home (if you want it). LVM allows for more flexibility if you dont want to drop everything into one partition or if your pretty sure you dont want to move partitions around in the future on the disk that your using. For instance, with LVM, I can shrink the / volume and increase the /home volume live, but without it, you have to do that offline (with a live cd) for the / partition. I think that LVM makes troubleshooting a disk harder if you do not fully understand it because of the additional layer of complexity but its used a lot of places and it adds quite a bit of flexability, so its worth learning. That being said, on all of my arch boxes I dont use LVM on /,swap,/boot because I dont change the layout (I leave mine 1: 500M /boot 2: 1-2x memory SWAP, 3 FREE /). LVM and crypto(dm_crypt) are two different things, unless I am overlooking something, and would not be comparable. Generally luks is pretty easy to do on say the /home partition, where you would more then likely keep all of your stuff. You would be able to use that with LVM or straight partitions. Here are some helpful links: luks (crypto): https://wiki.archlinux.org/index.php/System_Encryption_with_LUKS LVM: https://wiki.archlinux.org/index.php/LVM Arch install guide: https://wiki.archlinux.org/index.php/Official_Installation_Guide Hope that helps a bit, Dan On Sat, Jun 30, 2012 at 12:54 PM, brett michaels <[email protected]> wrote: > I've been reading and rereading the tutorials at archlinux.org in order to > do the install properly along with being able to customize the system. > This is a virgin 2Tb 7200 rpm HD that the system will be installed to and > there are no plans to share it with any other OS. > Are any special alterations needed to support LVM? > When I tried installing Centos alongside Mint on sdc, GParted said that LVM > was not supported(anaconda insisted on creating it). > Are there any advantages to LVM? > Why would anyone want to run LVM over dm_crypt? > I've been thinking of using GParted to manually partition the drive with > this setup: > > / (20Gb) btrfs > /boot (200Mb) ext2 > /var (20Gb) Reiser > /tmp..
