It's OK to have / on LVM. That allows adding more space if required later.<br><br>A typical Fedora/RHEL/CEntOS install will put /boot on a partition and a single partition for a physical volume. That partition is split between / and swap so that swap can float as well if you add more RAM later. / is all one big partition typically but later version of desktop installs make a separate /home.<br>
<br>As you are looking at RAID as well, make the md devices and put LVM on top. The caveat is you want swap on non-RAID as it handles itself sort of raid-like already. (That said, swap on raid is reliable but it gets slow on heavy used systems)<br>

I'm getting ready for the 3rd time installing Centos 6.2 on new server for home. We usually figure we get to install at least twice on a new OS and hardware. <br>
<br>
This time the re-install is to get the drive partitioning and soft RAID right. I didn't have the 2nd drive for the 2nd install. <br>
<br>
Normally our prior Fedora servers have been <br>
<blockquote>
/dev/md1 on / type ext3 (rw)<br>
/dev/md0 on /boot type ext3 (rw)<br>
/dev/md2 on /u type ext3 (rw)<br>
<br>

This time around I was thinking on using LVM, I guess to just get more experience with LVM. However, since you wouldn't want to risk resizing /boot or root filesystem, I see no point in them being in LVM. <br>
<br>
Primary drive is 1.5TB, of which 220GB is occupied by Windows7 boot, which I'd prefer to not disturb. <br>
2nd drive is 1TB. <br>
<br>
So, I'm thinking of a layout like this:<br>
<blockquote>
/dev/md0 on /boot type ext3 (rw) (whatever boot takes)<br>
/dev/md1 on / type ext3 (rw) (about 50GB)<br>
/dev/md2 on VolumeGroup00 (about 1TB)<br>
And logical volumes for /home and /u, which can be resized as needed between /home and /u<br>
/dev/sda? on /u2 (remaining 300GB, not Raid 1, just on the one bigger drive)<br>
</blockquote>
<br>
Is that going to work? Other thoughts? <br><span class="HOEnZb"><font color="#888888">
