I have a cluster that has been operational for some time and functioning flawlessly until a recent yum update. The last unflawed working kernel was 2.6.9-55.0.12.ELsmp. The current kernel is 2.6.9-67ELsmp. The problem appears to be some type of infinite recovery loop of sorts. It runs find for a few minutes, then the service restarts itself. What I am seeing in /var/log/messages is: Jan 3 11:17:47 engrfs1 clurgmgrd: [5614]: <err> nfsclient:skynet_disted is missing! Jan 3 11:17:47 engrfs1 clurgmgrd[5614]: <notice> status on nfsclient:skynet_disted returned 1 (generic error) Jan 3 11:17:47 engrfs1 bash: [27695]: <info> Removing export: 129.119.113.108:/mnt/disted Jan 3 11:17:47 engrfs1 bash: [27695]: <info> Adding export: 129.119.113.108:/mnt/disted (rw) It does this for every client definition on the service. After it gets to the last one, it then restarts the serivce: Jan 3 11:16:25 engrfs1 clurgmgrd[5614]: <notice> Stopping service disted_export Jan 3 11:16:26 engrfs1 clurgmgrd: [5614]: <info> Removing IPv4 address 129.119.113.180 from et h0 Jan 3 11:16:36 engrfs1 clurgmgrd[5614]: <notice> Service disted_export is recovering Jan 3 11:16:36 engrfs1 clurgmgrd[5614]: <notice> Recovering failed service disted_export Then adds the exports and starts services again: Jan 3 11:16:36 engrfs1 clurgmgrd: [5614]: <info> Adding export: 129.119.113.108:/mnt/disted (r w) Jan 3 11:16:36 engrfs1 clurgmgrd: [5614]: <info> Adding IPv4 address 129.119.113.180 to eth0 Jan 3 11:16:37 engrfs1 clurgmgrd[5614]: <notice> Service disted_export started And then starts over at the beginning again continuously. This is a production system and this behaviour is causing the clients to hang (of course) during the restart. Thanks much for your help! Sincerely, Doug Tucker
