That is how I'm looking at it. Saying that, I'm not very familiar with the inner workings of z/VM. All of our 100+ x86 Linux servers have / in LVM and over the past year we've had to completley rebuild a server maybe once. I guess I don't expect the 3am calls like everyone else because I've never had them before w/ Linux on x86. >>> On Thu, Aug 14, 2008 at 11:01 AM, in message <[EMAIL PROTECTED]>, Scott Rohling <[EMAIL PROTECTED]> wrote: <> [EMAIL PROTECTED]> wrote: > >> Is there a list of pro's and con's somewhere? >> > > There may be some list out on the web - but to me there are just a few: > > Pro: > > - Extending root can be done without restarting the guest, by adding a > volume to the VG and doing an ext2online.
