[StarCluster] weird errors

[Kai Li]

Hi,

My 20 nodes' cluster is running very well for 5 days. But after that I got
these following errors when I try to ssh node001 from master after the
cluster running for several days. So weird... Can anybody give me some
advice to solve this?


@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
b9:e0:61:b5:38:f9:25:8b:85:c5:3a:cf:82:e7:df:e7.
Please contact your system administrator.
Add correct host key in /home/kli/.ssh/known_hosts to get rid of this
message.
Offending RSA key in /home/kli/.ssh/known_hosts:273
  remove with: ssh-keygen -f "/home/kli/.ssh/known_hosts" -R node001
RSA host key for node001 has changed and you have requested strict checking.
Host key verification failed.

Regards,


Kai
