how to install ubuntu on lvm?

[leonchik1976]

But you should, I think.

[leonchik1976]

no, i don't anyone esle faced the same problem?

I'm quite sure you just don't know where to find it. When you set up the partitioning during installation you must set up the partitioning manually. Only then you can tell him to use raid, lvm or whatever you need. There are plenty of howtos around in the internet how one can setup lvm and software raid. Just stick to them.

I think you have to use the alternate installer in order to do more advanced types of installs like LVM and software raid

[leonchik1976]

alternative like what?

[coopstah13]

when you go to download ubuntu, there is what is called the "alternate installer" which is a text based installer (no you don't type commands, just no mouse)

Download Ubuntu | Ubuntu

click the link that says "alternative download options..."
it will expand some stuff and on the right side you will see the text-based installer

[leonchik1976]

ok, i'll try. thanks.
but in these days i think it's really weird that lvm not present on main installation

[coopstah13]

I don't think so. I think both LVM and software raid are somewhat more advanced. GUI installer is to be more simple and easy to use for most users, while advanced users would want to use text mode anyway.

can't remember i downloaded something fancy when i installed ubuntu the last time (about 3 months past sometime in the february) and i did not only install lvm, but software raid 5 over 3 physical disks with /boot on a separate raid 1 partition over all 3 disks. lvm however is needed as layer in between the raid and the partition tables. so not only lvm but far more things are possible with the most common ubuntu installer.

also, I'm quite sure there are no multiple installers around as it would just double the work to maintain them.

and finally to mention is that ubuntu is one of the most userfriendly environments. so many fancy things you cannot even get of "the apples" in a one-click user interface. either one wants to use a computer, or one wants to work with a computer. the first kind of type should not hassle with more than a default ubuntu install, which means automatic partitioning, which in turn means no lvm.

get yourself straight and navigate through the installer screen when you set up the partitions. there you'll find all you need. really.
