I agree that the crashkernel size has especially an impact on smaller system. And right now the size is with 128MB obviously mainly optimized for smaller system, but does not really take the needs of bigger ones into account. However, this is done in a better way on other platforms, where we have a setting that is based on ranges, which provides more flexibility, I think.
So I would suggest to introduce such a staged, range-based approach for s390x too, like "crashkernel=384M-1G:128M,1G-3G:256M,3G-:512M" The crashkernel setting is of course configurable, but hitting slightly better values by default would improve the user experience and reduce the need for manual adjustments - instead of having to adjust it 'all the time' (which of course a bit overdrawn). And btw. I would estimate that an avg. s390x system has nowadys about 4GB RAM; and with the new installer I guess we even have a slightly higher minimal req. for RAM anyway (and not much people will install with a higher RAM footprint and reduce it post-install - and I'm also not sure if it's possible to install on a system with only 384MB RAM these days ...). So could such a range-based setting become a valid compromise? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877533 Title: [20.10 FEAT] Increase the crashkernel setting if the root volume is luks2-encrypted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1877533/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
