Thanks for the response. I'll admit that I'm learning LVM as I go here. I _really_ liked the feature where LVM will mirror a LV..........provided you have THREE physical volumes. Yeah, that's real handy for a two drive SATA server. What happens when one of those PV bites the dust? <BR>
<BR>
<BR>
Now, I've already messed with logging in as root, unmounting /home and /u, and resizing both. <BR>
<BR>
However, I had to unmount them in order for the native LVM to be willing to do that. which makes perfect sense. <BR>
<BR>
How is it that you can resize / without booting to a rescue disk? And if you have to boot to a CD/Usb to resize root, well, is there any advantage to having / on LVM, or would it be safer to have / a regular non-lvm filesystem, so that the thing is more likely to survive a variety of events? <BR>

Maybe I'm doing it wrong, but I have found having /boot on a non-LVM partition and everything else managed by LVM to be quite useful. In fact, I had to resize a root partition on a server I was setting up just today (well, yesterday at this point) because I forgot to appease the great Oracle client with way too much swap space (I gave 512MB and it wanted twice RAM [60GB of swap?! Ridiculous]). It's also handy when you need to add a new drive into the mix for more free space. <BR>
<BR>
But I'm really just getting used to LVM myself.<BR>
