Summary

Stop using LVM in the default partitioning scheme.

Owner

Current status

  • Targeted release: Fedora 41
  • Last updated: December 17, 2008
  • Percentage of completion: 0%

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?
