13. Grow the /cms file system by entering the following command:

If the operation should fail, do the following:

a.Restore the original md.tab file by entering the following command:

# cp /etc/opt/SUNWmd/md.tab.mirror /etc/opt/SUNWmd/md.tab

b.Look up the error message in Chapter 4, “Troubleshooting.”

14.Enter the following command:

#metastat

Examine the output to make certain the disk drives you just added are part of the configuration.

15.Enter the following command:

# df -k /cms

The system responds by displaying file system information for /cms.

For example:

Filesystem	kbytes	used	avail	capacity	Mounted on
/dev/md/dsk/d21	xxxxxxxx	9	yyyyyy	0%	/cms

Check the response. Look for the “avail” figure for /cms (shown as “yyyyyy” in the example above). That figure should be roughly twice the figure recorded in Step 5.
