I have an issue with a relatively new xCAT-maintained cluster of redhat nodes.
We use xCAT and the associated DHCP functionality for system provisioning and
upgrades, but all of our nodes normally have static IP addresses. At long
intervals, we are finding that the ifcfg-eth* are being overwritten, causing us
to go in and add IPADDR and NETMASK lines to ifcfg-eth* files that no longer
have them, and restart the network service. At the same time, for example,
ifcfg-eth*.xcat files are created.
I suspect that dhcp is doing this, but would like to confirm before I try to
remediate.
RHEL 6.4
xCAT: Version 2.7.6 (svn r14451, built Tue Nov 27 21:57:27 EST 2012)
