Re: Now that I have working box, any problems with LVM?

I know, that's a subject that has generated more than it's share of
flamewars in itself }:-)

I myself tend to stay a bit on the conservative side when making these
choices. Up to now I still use ext3, but I am considering ReiserFS for
the new box...

I didn't try yet, but I seem to remember seeing an option for LVM during
the install. I might just try it out. I can always start anew if it
proves to be broken.

Thanks. I suspected as much, but wasn't sure.

Good info there. 

I've decided to go for it, but am still not sure whether I'll add / to
LVM too. Most of the time I make separate partitions for /, /var, /tmp,
/usr, /usr/local and /home (in that order). All the other filesystems
will go in LVM. I figure I'll just start experimenting with / in and out
of LVM and see what "feels" best to me. That way I can get a good feel
for things.

I would appreciate that very much. I'd give me something to build on.
