Hi, ssh STONITH is not for production use, Dominik mentioned it already but it cannot be said enough.
ssh keys aren't enough, you need "at" daemon to be running also. The way it works is that the intact node puts a "reboot" command into into the failing node's "at scheduler" then few moments later the reboot should begin. ssh-keys is step one atd start is step two on SuSE it should be insserv atd && rcatd start Regards, Ivan On Fri, 2009-01-09 at 14:57 +0530, Mujtaba, Sayed Mohammed wrote: > Hi Dominik, > I have already done that set up for ssh keys and able to login/ssh from > VM1 to VM2 and vice versa but still problem exists and also I tried > stonith xen0 > in place of external/ ssh but no effects... > > Thanks, > -Mujtaba > > > > > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of Dominik Klein > Sent: Friday, January 09, 2009 1:23 PM > To: General Linux-HA mailing list > Subject: Re: [Linux-HA] STONITH > > Mujtaba, Sayed Mohammed wrote: > > > > Hi , > > I am using heartbeat STONITH (external ssh ) for fencing nodes in > case > > of application failover .
