AFAIK, if LVM uses 4 disks and one of them fails, the hole file system is lost. With the usual system only the file system on the faulty disk is lost.
That's quite oversimplified, but it's more or less correct, as with RAID 0 (striping).
On the other hand, you get the disk space of the combined physical disks, and you can dynamically create and resize logical volumes (= partitions for your filesystems), given that you're also using a filesystem on top of those that you can resize dynamically (reiserfs or XFS can do that even while partitions are mounted).
I've been running quite often into users asking for help because they don't have enough disk space left, but they have that other or new disk... can't that be used.. etc... (and yes, I'm a long-time LVM user ;))

given modern disks are large, is it possible to have LVM strictly assigned at one disk, or separate LVM to each disk? sharing a partition between several disks don't seems so nice to me (when not strictly necessary), but when a drive fails, anyway all it's content is lost so... we could have to good and not the bad? jdd -- http://www.dodin.net http://dodin.org/galerie_photo_web/expo/index.html http://lucien.dodin.net http://fr.susewiki.org/index.php?title=Gérer_ses_photos --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory-unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory-help@opensuse.org
