TABLE 8-1

You can also use the Solstice Domain Manager (or other SNMP-conformant program) to monitor the Media File System (MFS) disks. The SNMP agent for the Sun MediaCenter server, sms-vod, has an SNMP trap, Disk_Failure, that allows for automatic notification when a disk failure occurs. This trap is particularly significant if a disk failure is followed by a reboot of the server. If this occurs, your SNMP manager retains a record of the disk failure, while on the server, notification does not persist across a reboot (see note on page 8-12). You can also create an event request that will report when user-specified thresholds are met or exceeded for certain attributes. See Appendix A for discussion of the attributes of the video server MIB, as well as instructions for enabling trap handling in Domain Manager.

8.2MFS Utilities

This section describes MFS utilities that you can use to display information about

the MFS, create an MFS, or write data to a new data disk in the MFS. lists these utilities.

TABLE 8-1MFS Utilities

Command

Function

 

 

 

mfs

df

Displays disk information for the currently-mounted MFS.

mfs

diskusg

Displays disk usage for a specified MPEG file.

mfs

repair

Writes data onto a new data disk after failure of a data disk.

mkmfs

Creates the MFS. You need to invoke this utility only if you

 

 

reconfigure the data and parity disks that make up an MFS.

 

 

 

If you install Sun MediaCenter software in the default location (/opt/SUNWsms), the path to the MFS command-line utilities is /opt/SUNWsms/bin. The exception to this is mkmfs, which requires a path of /opt/SUNWsms/mfs/bin.

8.2.1mfs df

The MFS’s mfs df utility is analogous to the Unix file system df (1B) utility. mfs df displays the amount of disk space occupied by currently-mounted MFS file system, the amount of used and available space, and how much of the file system’s total capacity has been used. By default, the MFS’s df utility reports space in increments of 64K blocks. With the -koption, mfs df reports space in kilobytes.
