CentOS Community, It is to my understanding that the /boot partition should never be placed on LVM and should be a physical partition on the hard drives (or on top of a RAID array). Is this an accurate statement? Also please advise if the SWAP filesystem is safe to be placed under LVM, or if this should be a hard partition / hard limit as well. I am unsure if boot issues or any filesystem issues would be caused by placing them on LVM. Please educate me if possible. Thanks in advance for the information!

Is this an accurate statement?/boot on LVM is quite safe as long as it is below 2GB. Hopefully it is.> Also please advise if the SWAP filesystem is safe to be placed under > LVM, or if this should be a hard partition / hard limit as well.Swap on LVM is quite safe; in fact it is desired. -s

Is this an accurate statement?Not necessarily "never" but not if your boot loader is GRUB 0.95. /boot should be on a regular partition or an MD RAID1 partition on storage that is available to the BIOS (single drive or RAID volume on a controller with a boot ROM).
