hi all

have 2 windows servers 2008 r2 enterprise configured nfs storage server in (active/passive) replication cluster.
nfs storage mounted on linux servers.
every time power on environment, find nfs become not responding(from linux servers side) several minutes , responding(the services on nfs servers , running , there isn't errors in event viewer)
attitude keeps repeating while (may hour or two) , after works fine.
happens after power on environment.

ideas might cause this?

additional information:

  • the physical storage sas configured raid 5.
  • powering on sequence:
  1. power on physical storage
  2. power on windows nfs servers
  3. power on linux servers

nfs server not responding great error message, meaning error message isn’t totally ambiguous  nfs client can no longer communicate nfs server.

you may following check:

  1. ping netapp filer ip , dns name or short name.
  2. on netapp filer, try ping nfs client(s).
  3. confirm ip configuration on nfs client , servers correct
  4. confirm correct nfs version enabled
  5. check nfs options on netapp filer correct
