Accessing the Omneon MediaGrid Table 5. Mount Options This should automatically load the Linux FSD. 2. Type the following if the Linux FSD is not automatically loaded: modprobe omfs Additional Mount Options Using Linux The following file system mounting options are available using the Linux FSD. IMPORTANT: With the exception of the “readahead” option, do not modify any of the values in this table without first contacting Technical Support. Option Description username=xyz Specify the required user name. You are prompted for a user name if it is not specified. password=abc Specify the required password. You are prompted for a password if it is not specified. domain=abc Specify the Windows domain name. filelimit=m Specify the maximum number of concurrently open files. Used to prevent the system from running out of memory. m=0 yields no limit. The default is 16. readahead=n Specify the number of slices to cache with ReadAhead caching. Supported numbers are n>=0. The default is 3. • For n>=1, n many slices are cached. • For n=0, 256k bytes of data are cached. Some degree of caching is required to maintain acceptable system performance. nocrconread Disable CRC check on read. mode Enable file permissions. This displays the proper file permissions when listing files and directories. It also enables the ability to set permissions using standard Linux commands (e.g., chmod). Enabling this option decreases the speed at which files and directories are listed. exportfs Allows a mounted file system to be shared using NFS. lock=abc Specify the lock type. The following types are supported: • none = locking is off • adv (default) = advisory locking • mand = mandatory locking readpri=abc Specify read data priority. The following types are supported: • bg (lowest priority) = background • low = low • nr (default) = normal • rt = real • sys (highest priority) = system 164 Installation and Configuration Guide
