I'm rearranging some NFS mounts - tidying up and decommissioning them.

As part of this, my 'management' server has gained a huge load average, because of nagios kicking off 'stat' on the NFS mounts.

All the processes have gone into state D - uninterruptible sleep.

Is there a way - short of rebooting the box - that I can convince these processes that the mount they're accessing is dead and gone? I know they're irrelevant, but the kernel masks interrupts to these processes.

    if you are in newer kernel version, you can kill this process. – c4f4t0r Mar 09 '15 at 13:33
  • did you remove the mounts from the server (so they don't appear in df -h anymore)? Otherwise you can do that with "umount -fl /volume". If the processes don't die after that, you can indeed kill them. – Jeroen Mar 09 '15 at 13:44
  • Yes, mounts have been removed. Processes were still stuck. – Sobrique Mar 09 '15 at 15:02
