Issue
- NFS mounts do not honor the
intrornointrmount options in RHEL6
Resolution
- The
intrmount option has been deprecated. A snippet from the man (man nfs) page detailing this change can be found below:
The intr / nointr mount option is deprecated after
kernel 2.6.25. Only SIGKILL can interrupt a pending
NFS operation on these kernels, and if specified,
this mount option is ignored to provide backwards
compatibility with older kernels.
- Hung NFS operations may be able to be killed by issuing a SIGKILL interrupt by killing the process inflicting the hung response:
# kill -9 <process>
