Is there any reason to use LVM on a personal desktop install of CentOS? It seems to me, for my purposes, that LVM is just a pain in the neck -- although I've always just let CentOS set it up during the install in the past. I would like to be able to use parted to resize partitions when I want to, and also I'd like Vector Linux to be able to read and write data to the CentOS partition. Would I be missing something by not installing LVM, or is this mostly for server purposes anyhow?
LVM adds flexability that regular partitioning can't.
Just to add some more info to the conversation. Yesterday i found out that if you have a modern SSD and are planning on using RHEL6 or CentOS6 then LVM will not support the "TRIM" ATA command thus there will be a significant decrease in the write perfomnace of the drive with time. Linux swap will use it but the only way to enable this feature is if your partitions are native ext4 and you use the "discard" option.
Thus TRIM will not be enabled by a default install except for swap space.
