The thing to remember tho, the drive failed. That is why you had the problem. That isn't the fault of LVM. That is a defective drive. From what I've read, you can have a drive fail, remove that drive and lose the data from it but keep what is on other drives. If you have all your files on a single drive with no LVM and that drives fails suddenly, what is different? The important part, monitoring your drives and at the first sign of problems, replace the drive. That is true whether you use LVM or not. Right? I might add, long before I started using LVM, I've had drives to fail and either had to backup real quick or lose data. While LVM can cause a problem, I suspect it is rare if managed properly. For me, and many others, it adds many benefits to managing data. Just recently, my home partition was starting to fill up. It was made up of two 3TB drives. I replaced one of the 3TB drives with a 6TB drive. Because I use LVM, it was painless and easy. If I hadn't been using LVM, like in the past, it would have been much harder to do. I might add, I would have had to replace with larger drives, which also cost a good bit more. Even from my simple setup, LVM adds more benefits to managing data and drives than it does risk. The biggest thing, placing blame where it lies. Blaming LVM for a drive dying is placing the blame on something that wasn't the root of the problem. The dying drive was the problem, using LVM or not. Back to Firefox, I recently did a emerge -e world with no change. It still does it on occasion. So, it's not some weird quirk where something needs to be rebuilt after a upgrade. Still a annoying problem. Thinking on that firefox-bin package next. :/ Dale :-) :-)
