Hmm... Sounds good. Thanks for pointing out a reference. > So i was thinking this value could work. I've find some example where they > you have to put huge value like 10000000 to use all available space left. One thing I don't like is that the last partition is always as large as possible. When using lvm I would rather limit the size and keep the rest in reserve. Using a /dummy placeholder is the only way I have found to do that so far. > I've tried so many things to make it works that i can't really remember why > i try to create an extended partition explicitly for lvm Without keeping very careful notes in a lab notebook it is easy to have all of the attempts blur together. > > Since having a separate /usr isn't supported anymore I didn't include > > it.

So i assume it was correct as long as i use an initrd. If you have a separate /usr currently everything will still work fine. But there has been so much <del>flames</del> discussion about it that I wouldn't recommend setting up new systems that way. I am not going to write more here about /usr since there is already a huge amount of discussion available elsewhere. > I'm not really comfortable mixing mysql data or others stuff like that > (which are in /var/lib/mysql by default and can grow a lot) with my logs > files even with logrotate. But it's only my opinion. Oh, /var/lib/$FOO. In that case why not make a partition specifically for /var/lib/mysql or other /var/lib/$FOO things? That is what I do. I always allocate as specific lv specifically for large disk uses like mysql or apt-cacher-ng or or kvm whatever. > > Then after the creation later I unmount /dummy and lvremove the > > partition putting that disk space back into the free list.

If I had my choice instead of partman I would shell out to an external script that I would write to handle the partitioning and file system creation. I keep thinking there must be a way to do that. It would then make a lot of this much easier. (Easier for me anyway.) > So i finally ended up with this recipe : I think you duplicated that paste. But regardless I am happy to read that you solved your problem. Good deal! Bob
