http://bugzilla.opensuse.org/show_bug.cgi?id=999776 Bug ID: 999776 Summary: System Install does not warn that memory is too low to perform Leap install. Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.2 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Installation Assignee: yast2-maintainers@suse.de Reporter: carlos.e.r@opensuse.org QA Contact: jsrain@suse.com Found By: --- Blocker: --- I have run several tests of installation of Leap 42.2 beta, build 164 (both Net and full DVD) under vmware player, with different memory sizes, to find out what happened and what would be the minimum amount of memory needed (in 128 MiB steps). The installation failed or crashed in different manners. There was no warning of low memory nor suggestion to add a swap partition early during install. The values I found were: ** The minimum for the NET installer is 896MiB RAM, probably somewhat less. [...] ** The minimum for the full DVD install is 768MiB Or if you want to be conservative, 1 GiB. Apparently the release notes mention 1GiB, but then the installation system does not warn, yet it could: you could adjust the values:
MemLimit Amount of free memory in kB below which linuxrc will ask the user to set up a swap partition. MemLoadImage Amount of free memory in kB below which linuxrc will not copy the root image into RAM. MemYaST Amount of free memory in kB below which linuxrc will start YaST in text mode. MinMemory Amount of memory in kB below which linuxrc will refuse to start. Defaults to 0.
I performed an installation with 512 GiB of RAM, just by creating a swap partition and enabling it while YaST was trying to start. The optimal procedure in low memory would be to boot with "startshell=1" as booot parameter, which gets to a text console; there use fdisk, mkswap and swapon, and finally, type "exit" to start the installer, in graphical mode. It runs quite snappy :-) -- You are receiving this mail because: You are on the CC list for the bug.
