Avoiding the Network Stage SCP Hang

NOTE:  This fix is for InfiniDisc/OSVault versions prior to 4.1.12

If you notice that a stage of a file back from network storage is not completing, this might be due to an SSL/SSH protocol issue where the network socket does not close correctly.  The problem has been traced to a standard I/O issue in the DMAPI daemon.     The SSH/SCP program that is invoked is run from an init.d script, rather than a user terminal session.  That causes certain network problems in the programs.

The fix for this is relatively simple, just ensure that the DMAPI daemon is started with its standard I/O redirected to /dev/null.  To do this, edit the /etc/init.d/dmapid file and change the dmapid start line as follows:

Change

/usr/local/bin/dmapid /cache  &

to

  /usr/local/bin/dmapid /cache >/dev/null </dev/null 2>&1 
&
