Not all entries in SYSCTL being implemented

[louielouie]

New mb, cpu & hd deserves new Linux distro and my sysctl.conf was copied directly from my Mandriva 2010.2 distro and now two entries do not get updated on boot but I can "sysctl -p sysctl.conf" and they will be updated:

vm.swappiness = 100

vm.dirty_ratio = 35
vm.dirty_background_ratio = 20

net.core.rmem_default = 8388608
net.core.rmem_max = 8388608
net.core.wmem_default = 8388608
net.core.wmem_max = 8388608
net.ipv4.tcp_rmem = 4096 87830 8388608
net.ipv4.tcp_wmem = 4096 87830 8388608
net.ipv4.ipfrag_low_thresh = 262144
net.ipv4.ipfrag_high_thresh = 393216

Those two settings really help XFS or JFS (during benchmarking for database) so I was wondering if this has been noticed before and is there something I can do to fix it? I didn't find anything useful searching on 'sysctl'.

I checked Mageia 2 which does not seem to have the feature and I checked the sysctl.conf for any odd characters with hexedit so I'm kinda confused. Perhaps I'll try a different order...

Why not just put a call for "sysctl -p" in /etc/rc.d/rc.local as a workaround?

[louielouie]

I have for now. I'll jump to Mageia2 later.

Should be reported as bug IMHO: https://wiki.mageia.org/en/How_to_report_a_bug_properly
