nointr blocks signals during the io itself. Prevents short ios.
AFAIK, Oracle requires a similar mount option with NFS too.

Btw, why Oracle like nointr? Our analyze shows that 'intr' can be used
instead in all cases andf is much safer. (at least for the NFS)
For NFS., intr means that mount is hard (application never got IO failure
but just try IO forever - it's discussional too but we can agree with this
approach)
BUT if can be killed or interrupted. So that if IO is frozen and other
application sends shutdown signal (such as kill -9) then application will be
killed.
Without intr, if your NFS server died, you wil not be able to shutdown your
server without power reset (or reboot -n -f in some cases).

Ensure you have mounted the volume storing the
ocr and the voting diskfile with the "nointr,datavolume"
mount options.
