Hello
for ethernet and infiniband I've been searching for suggestions to tune sysctl.
for IB I found this and similar per Mir in main forum:
https://www.ibm.com/support/knowledgecenter/en/linuxonibm/performance/howtos/incarp.htm
"The correct setting of a multi-homed IPoIB host is achieved by using a different PKEY for each IP subnet. In some cases a host could have multiple interfaces on the same IP subnet, and you need to prevent a peer from building an incorrect ARP entry, or neighbor."
I am having an issue on our 10G ethernet ceph cluster , and before scrapping it and changing to IB I thought perhaps there are some sysctl setting which could help.
I saw this in from the IBM article:
Optional: For a global setting, run the following command:
Now I've broken things before by testing settings on a production cluster.
Does anyone have suggested sysctl setting for ethernet network bond?
thanks for reading
