Re: [gentoo-user] How many GB for / partition?

For example, in your setup, how do you make /var larger, if need be? With LVM, it would just be a matter of lvresize -L+512m /dev/Volume00/Var. You also wouldn't waste so much space. Alexander Skwar -- BOFH Excuse #126: it has Intel Inside I do agree with almost all you said (like - for instance - having separate filesystems for the different top-level directories). Indeed, this (using several small filesystems mounted together instead of one large filesystem for /) is a technique that can be applied to speed things up (have a look at http://gentoo-wiki.com/TIP_Speeding_up_portage to see how Portage may profit from the use of small filesystems). Having said that, I would like to suggest that instead of using LVM, the top-poster might be better off by using EVMS (http://evms.sourceforge.net) since EVMS sports different UIs for all kinds of users (CLI, ncurses, X) and automates many tasks like resizing etc. Kind regards Martin Eisenhardt -- Dipl.

I don't quite get, why people still do the old style partitioning. Correct me if I am wrong, but with lvm you do not have control over physical placement of your partitions. Right? No, wrong, I am sorry :-D You might let LVM choose where to put the extends for a newly created logical volume, but you might also tell LVM where to put it. So if you use lvm even for swap, lvm might place it anywhere on disk, on the beginning (first cylinders, highest speed, i.e. ~50 MB/s) or at the end (in my case ~30 MB/s). You can tell LVM to put it wherever you want, see above. Utilities like hdtach (win-world, I do not know something equivalent for linux) show, that read/write speed is not constant over the whole disk (number of sectors on outside cylinders is much higher, than on the inside cylinders). Correct, but then - does the performance of your system really depend on the speed of your swap device? If so, consider upgrading RAM. You will *never* get swap devices so fast that it is really pleasurable to work with them. In some cases it might matter to partition disk wisely, for example when someone is doing tv/video grabbing, he needs maximum transfer speed to avoid frame-dropping, so it might be worth putting /home or /tmp somewhere near beginning of disk (outside cylinders). Similar for swap, plus optimising of head-movement, etc... Again, see above. Regards Martin -- Dipl. Wirtsch.Inf.(Univ.)

Or are you talking about the allocation policy? Like --contiguous y? Well, first of all, you can pass lvcreate a list of physical volumes that are then used to allocate extends for the newly created logical volume. By the order of LV creation, you determine the sequence of LVs on the PVs (or ore correctly, the sequence, in which the extends of one or more PVs are allocated to one or more LVs). Then, you may use lvmove to move a LV to another PV. You may use lvsplit to split a LV into two or more parts and then use lvmove to move these part-LVs around. Thirdly, you can (either by hand or by using a more sophisticated tool like EVMS) alter the mapping of LV extends to PV extends. There are surely even more ways to tell LVM where to store LVs, but these are the ones that come immediately to my mind. Kind regads Martin -- Dipl. Wirtsch.Inf. (Univ.)

I seem to remember that in uk they spell these words with ou and the lazy and/or progressive americans have shortened it down to only o for themselves... IIRC it is just the other way round. The Pilgrim Fathers came from England to Cape Cod (near Boston) and brought with them the English language. At that point in time, color was spelt color - even in the UK.
