I don't know if either Centos or Ubuntu can do in-place version upgrades, but if not, they should certainly run from release to unsupported status. My current server installation is a new one, but previously it ran through several Debian stable version upgrades and many years, and a couple of changes of hardware. There is such a thing as software rot, and it certainly affects applications, but the OS of Debian stable should run pretty much forever. > > I am new to the debian users group, because I found out that a user > group existed much later.

No software carries any kind of warranty, not even the famous Windows, but the warranty should certainly cover the hardware if it isn't physically abused. Software warranty service is pretty much limited to reinstalling Windows with loss of all data and applications, which any user can do themselves. > The third reason is I simply do not > at the moment have the time to backup the existing hard drive before > installing a new operating system on it, and also that should it > become unusable or stop functioning (I had debian installed on a usb > 64 gb of size that stopped booting).. Ah, USB sticks *do* stop working or lose bits without warning. Well, so do spinning hard drives, but not usually in less than about five years, often much longer. > > Yes I did figure out that it was lvm2 package that was needed, and > lvs is actually one of the internal commands for lvm2 as well so it > could be run from the console lvm2 prodives.

To be honest, I've had it installed for many years, and only occasionally used it. Drives are now large enough that I don't outgrow them in the lifetime of the hardware. In addition to adding and removing drives, LVM does allow online backups, if you've left enough unused space. Read about snapshots. -- Joe
