Comment XFS and power drops don't mix. (Score 1) 271
One of the things both mentioned on the gentoo-user email lists and in the XFS FAQ is that if the power drops on a system using XFS, only the *metadata* is journaled, not the data.
This can get bad fast. With a full 30 seconds between disk updates, having the power cut means binary NULLs in any file updated since sync. (http://oss.sgi.com/projects/xfs/faq.html#nulls)
Short version: If you're using XFS, make sure you are careful to have clean power available, unless you don't mind file corruption. If no clean power is handy, stick with the usual journaling filesystems.
