+++ This bug was initially created as a clone of Bug #1493069 +++ I'm cloning the RHEL-7 BZ, with the same questions for IBM, but in regards to Fedora and the future of Fedora/RHEL. ---------------------------------- Therefore, I would like to hereby ask IBM representatives, what should be correct default values on IBM's s390 (and s390x if needed) architectures for these settigs on Fedora? ---------------------------------- # Kernel sysctl configuration file # # For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and # sysctl.conf(5) for more details. # Controls the use of TCP syncookies net.ipv4.tcp_syncookies = 1 # Do not spend as much process time too early to write out dirty pages vm.dirty_ratio = 40 # Increase the average time a process runs continuously and also improve the # cache utilization and server style workload throughput at minor latency cost kernel.sched_min_granularity_ns = 10000000 kernel.sched_wakeup_granularity_ns = 15000000 kernel.sched_tunable_scaling = 0 kernel.sched_latency_ns = 80000000 # Controls the maximum shared segment size, in bytes kernel.shmmax = 4294967295 # Controls the maximum number of shared memory segments, in pages kernel.shmall = 268435456 ---------------------------------- (https://github.com/fedora-sysv/initscripts/blob/master/sysctl.conf.s390) ---------------------------------- Would IBM be okay with completely removing all of these settings, and using default kernel values? We would like to drop that configuration file in Fedora completely, and use the systemd/kernel default values. (We currently do this for other architectures using Fedora.) Thank you in advance! ---------------------------------- @dhorak: Please, forward this request to IBM. Quick response from IBM is welcomed.
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle. Changing version to '28'.
Let's just remove them, and see if anybody complains.
yes, drop it
Duh, it was already dropped in initscripts-9.78-1.
