I was trying to figure out why our new sl6-64 hosts appeared to have broken nfs locking when migrating from a working el5 (centos) setup when I found a Debian bug report that appears to cover the behavior. The el5 hosts have no trouble with ip literals in the mounts. Whereas a sl6-64 host with all updates: May 25 21:12:15 a rpc.statd[5850]: No canonical hostname found for 172.16.255.14 May 25 21:12:15 a rpc.statd[5850]: STAT_FAIL to a for SM_MON of 172.16.255.14 May 25 21:12:15 a kernel: lockd: cannot monitor 172.16.255.14 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=579397 Should I submit this upstream? -- Kelsey Cummings - [log in to unmask] sonic.net, inc.
