The mfs diskusg utility is useful in conjunction with mfs df. You can compare the output of mfs diskusg, the amount of space a file would consume, with the output of mfs df, which tells you the space available.
The following is an example of the use of diskusg:
server% mfs diskusg size=1280000000 rate=4000000 format=MPEGTS
20480
In the example above, you obtain the number of 64K blocks consumed by a 1.28 GB file, encoded at 4 Mb/sec., and encapsulated in MPEGTS format. This is the number of data blocks, not parity blocks. Using the
server% mfs diskusg
Redundancy set size 4 zones 2 size 1280000000 Psize 188 Data drives 24 Parity Drives 6 Data blks 5120 Parity blks 1280

8.2.3mfs repair
The mfs repair utility reconstructs data for a failed disk using available parity information, writing this reconstructed data to a new disk. It can also perform consistency checks on the MFS, including reclaiming unused blocks, and can be used to explicitly fail a disk.
You can use mfs repair while the Sun MediaCenter server is running and delivering video streams, or when the server is halted.
