Fedora and LVM

Since it seems that "lvextend --resizefs" generally works for common FSs, it's certainly worth a try, but the lack of documentation and HOWTOs mentioning this option doesn't fill me with confidence.

While you are here: I think that the LV size should be larger than the FS size by 2 x the LVM physical extent (PE) size. Is that correct?

The LVM HOWTO at tldp hasn't been updated for several years.

No. Where did that idea come from? LVM doesn't reserve any space *inside* the LVs it creates! The filesystem can use the entire LV if it wants to.
