Current status

• Targeted release: Fedora 42
• Last updated: December 17, 2008

Detailed Description

LVM provides very little benefit for most Fedora users, at the cost of performance and complexity:

• Certain filesystem features (ext3 barriers) are unavailable when run on top of LVM.
  • This is one of the root causes of the Firefox 3 hangups with fsync()
• Software RAID performance is greatly reduced when layered on LVM.
• LVM partitions are not automatically assembled by the desktop systems.

Benefit to Fedora

New Fedora installs will not use LVM unless specifically requested - experts in storage administration can still set up volumes however they like.

Scope

• Patch anaconda to change the default partition layout:
  • /boot on the first available disk
  • / expands to fill the largest available disk
  • But what do we do with the rest of the disks?
