lockd recovery failure

lockd recovery failure

[mehta kiran]

Hi , 
    I have RHEL 4.0 beta2 installed on my machines.
    NFS server run on these machines.
    NFS client runs on machine with sles9 sp1 beta3 
    installed.

    I want to achieve NFS lock failover on cluster
    For this , i have a floating ip which floats
    on cluster machines

    rpc.statd is runnnig with commandline option -n
    i:e rpc.statd -n  <virtual ip>

    But when NFS server fails over to other
    machine  , client gets SM_NOTIFY message but
    it does not reclaim locks.

    In var/log/message following is the message 

    statd :NOTIFY called
    lockd: nlm_host_rebooted(base ip of server)

    So the reason for lock recovery is that
    notification is given to client using base ip
    of server and not the ip specified with -n 
    option.

    However , when I have above mentioned redhat
    machines and RHEL 3 Update2 client everthing
    works well(sm_notify recevied with ip in 
    -n option)
    Also , if I use sles9 sp1 beta3 server and
    sles9 sp1 beta3 client everthing works

    So , I am not able to figure out the 
    component which has problem.
    Is it sles9 sp1 beta3 client or RHEL 4.0
    Beta2 NFS server

thanks,
  kiran

The lock recovery in the 2.6 does work.... I've recently sent out 
server, client and statd
patches that should take care of the problem.... These patches will in 
the RHEL4 RC
release.
