  • EMS logs:
    node01: kernel: nblade.nfs4sequenceinvalid:NOTICE]: NFS client (IP: 10.10.10.100) sent sequence# 104017726, but server expected sequence# 103564588. Server error: BAD_SEQID.
    Note: This message is generic, further analysis is required.
     

  1. Enable sktrace:
    ::*> debug sktrace tracepoint modify -node * -module Nfs4LockErr -level * -enabled true
  2. Collect sktrace logs via full ASUP or collect manually (see Additional Information)
  3. Find sktrace.log entry to confirm: nfs_jukebox is set
