Verifying NFS Share is Exported by ContentBridge
To verify that each ContentBridge has exported the NFS share correctly:
1. Type the following command using the client Linux machine:
showmount –e (ContentBridge IP address or host name)
You should see the following output (“cb1.mediagrid.com” is an example host name):
Export list for cb1.mediagrid.com:
/mnt/omfs/mds/csloh/omfs/fs0 0.0.0.0/0.0.0.0
/mnt/omfs/mds/omneon/omfs/fs0 0.0.0.0/0.0.0.0
The output from the command “showmount -e cb1.mediagrid.com” lists
/mnt/omfs/mds/omneon/omfs/fs0 as one of the NFS shares available from the ContentBridge.
To mount the NFS share:
Type the following using the Linux client machine:
mount –t nfs cb1.mediagrid.com:
/mnt/omfs/mds/omneon/omfs/fs0 /mnt
Opening Network Ports to Enable Client Access
Specific network ports must be open to enable client access to Omneon MediaGrid. This is
particularly important if any security measures, including firewalls, are in place.
Omneon MediaGrid clients must connect to and communicate on TCP ports 10600-10604; UDP port
111 must be open as well. Note that these ports must be open for the entire subnet in which Omneon
MediaGrid is contained.
Contact the customer network administrator for assistance.
Managing Memory Usage by the File System Driver
The amount of memory allocated to memory buffers is controllable. Each client FSD (Linux,
Windows, and Macintosh) allocates memory buffers to optimize performance. This allocation of
memory takes memory away from application use. In general, the memory usage of the FSDs should
be minimized unless an application requires a large number of simultaneous files to be open.
The following parameters are available to control memory usage by each FSD.
• Filelimit (Linux FSD only). This parameter controls the maximum number of simultaneously
open files the Linux FSD supports. The default value is 16. Increase this value as necessary to
support an application’s requirements. Note that increasing this value increases the amount of
memory used by the Linux FSD. Increasing it too much may prevent an application from running
due to memory starvation.
