In the LVM-HOWTO, which may be out-of-date by now, talks about the difficulty of upgrading from LV1 to LV2 if one has used an LV for /. What are the prospects for future difficulties when LV3 comes along?
I've upgraded from LVM1 to LVM2 with / on a LV. Without any problem.
Obviously, I don't know how LV works internally. If the root filesystem get corrupted, how do I fix it from a recovery shell (e.g. the install USB) if its on an LV? If this is trivial, then is the thing to do to make all of the disk a PV then have LVs for everything?
It is probably a confidence problem.A corrupted root file system is not better than a corrupted root over LVM.
