How much RAM do you have? The old rule of swap=4*RAM is not valid anymore. swap=RAM is often plenty, you might even run without any swap at all. # Auto configured # # size (1k) usage(%) mountpoint # 128990 39 / # 218670 0 /tmp # 144100 102 /usr # 218670 0 /var I can't believe only 144M were allocated to /usr. Sysinstall is known to have problems when resuming a failed installation. Have you tried starting all over again or resuming a previous install? # - What partition was it running out of space on? # # /usr the 102% was something confusing /usr should at least be 250M (that's what is filled on my system right now, with /usr/src, /usr/ports and /usr/local being different partitions). If you want to compile everything from scratch, go towards 600MB. The >100% is due to 8% being reserved for root, so disks are full at 108%. # - Have you selected to install the ports tree? # i choose the Standard installation # later minimal. Okay, you will be asked for the ports tree after that. It's 30M in /usr/ports but needs a lot of files (i.e. inodes, which are a fixed number per file system). # suggestion: # Teach the installer about minimum requirement. Then grow from there. # I guess the 2G would be big enought to hold the entire CD but the # 1.3G Swapspace brakes the calculation (ca. 780MB ram *2 ). Ah, that's were you got the number from: Swap space is a little tricker, and the rule of "2 * MEM" is simply a best-guess approximation and not necessarily accurate for your intended usage of the system. If you intend to use the system heavily in a server or multi-user application, you may be well advised to increase this size. You may also create swap space on multiple drives for a larger "total" swap and this is, in fact, recommended if you have multiple, fast drives for which such load-balancing can only help overall I/O performance. Well, you have an unusual system: heaps of RAM, tiny disk space. The sysinstall defaults and help text are good for RAM << diskspace. # perhaps you can boot here again and check if the installation # is working. # # An other problem is the whole logic of installing. when the installation # breaks because of lack of space the system tries to install further. # lack of space is a major error and should at least stop and go the main menu. I'm afraid this failure mode is too rare and hard to reproduce on purpose for anyone to investigate. Development of sysinstall is virtually ended in favor of a completely new system, so don't expect to much. It's age shows and it has it's quirks that probably won't get resolved before it is retired. # feel free to ask about more details. i will keep that (broken) state for # the moment. Please reinstall from scratch with less swap (say 256M), that should allocate almost all your extra space to /usr.
