With all due respect, the fact that one of us can't imagine the need for some technology doesn't say much, one way or another, about whether a general use case exists. In general, I find this attitude amusing, but you may have a point W.R.T. LVM. Some people have high skill and comfort levels working with LVM, and find all sorts of helpful uses for it. (Me, for instance.) But I work with more experienced UNIX/Linux admins who start cussing and moaning whenever they need to interact with it, and if you offer to help, the answer is often something along the lines of "You can help by getting rid of LVM!" I see similar sentiments on the mailing lists, too--some people really dislike it. I wonder whether it might be a solution in search of a problem. I can rattle off a list of LVM applications that have helped me, in the past (live backups w/ snapshotting, transparent expansion across new disks), but that never seems to convince the anti-LVM crowd. When we get into lunch-hour debates about the merits and flaws, the usual responses are along the lines of "But you wouldn't *need* to do any of those things, if you'd designed your system correctly." I think you made a similar point, in your emails. But the flexibility is great, and I can think of dozens of situations where LVM's features saved me hours and days of time, or an inconvenient reboot, or just simplified some disk operation for me. I think the difference is that I know LVM *really* well, so I'm never frustrated by having to remember how the hell some obscure command option is supposed to work, or how to recover a VG with a missing PV when a RAID disk fails. But just to bring this back to the topic: From the day that Fedora re-unites /boot and / on a single LVM volume, I will henceforce script a YUM pre-upgrade hook that automatically takes a "before" snapshot of the entire system, for idiot-proof rollback if anything gets out of line. That will be a hell of a neat trick. -Ryan -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
