I accept your remark and thanks. I am planning to use the server mainly for MySQL and need some space for Apache. This is why I have more than 100GB for /var. I may need more spcae for MySQL databaes in the future and this is why I want to to with LVM Thanks again Yaovi --- En date de : Jeu 2.7.09, Filipe Brandenburger <filbranden at gmail.com> a écrit : De: Filipe Brandenburger <filbranden at gmail.com> Objet: Re: [CentOS] Partitionning for future.

It really depends on what you are trying to do. You did not use LVM for /tmp and fixed it to ~500MB, but I can't tell you if that is going to be enough for you or not, only you can tell that based on the applications you are planning to run on this machine. If you are not sure, I would at least suggest that you also create /tmp on LVM, that way you can grow it if you really have the need for more. Yes, it is OK to have /tmp and a tmpfs for /dev/shm, they are different from each other and each of them needed for different purposes. Personally, I think you should only create so many partitions for your system if you really know what you are doing. While there are advantages to having separate partitions (different I/O requirements for particular applications, limit damage caused by an application filling up the disk, in which case the root filesystem might not be affected) it brings more complexity and more management requirements. While LVM alleviates some of the problem, it does create its own as well. If you are not sure of what you are trying to accomplish and cannot come up with specific requirements of what you need, I would recommend you to create only a /boot partition (physical partition) and a / partition on LVM and that's all. It will probably not be the ideal setup, but good enough for most cases, and it will be the one that will require the least management efforts.
