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()
- This is one of the root causes of the Firefox 3 hangups with
- 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? - Maybe we should use LVM only for system with more than one disk?
