Prints the maximum possible size for an array without actually creating an array. -n, --name Identifies an array with a user-supplied name. The name can be up to 30 characters, but only 17 of those characters display in the BIOS. -p, --priority Sets the background initialization task priority from 1 to 10, with 10 being the highest priority. For redundant array types only. -led, --leave-existing-data Leaves the existing data on the disks untouched after the array is created. This option can be used to try to recover user data when an array has been accidentally deleted or the configuration information is lost but the data is still intact. Unless you immediately recreate the array after deleting it and no other tasks have been performed, the likelihood of recovering data with this method is very low. -d, --disk A required qualifier used with the --create option to specify the disk or disks to be included in the array. -sa, --scan-array Specifies that a background array scan should be continuously run whenever the array is idle (Default is off). -z, --zero Zero the array in the foreground. This method is faster than doing a background consistency verifies if the array is a redundant type. For non redundant types the zero option can be used to verify all blocks in the array can be accessed. EXAMPLES Example: Create a RAID5 set of the maximum possible size using all disks. rcadm -C --raid5 --disk * Example: Create a RAID1 set of the maximum possible size, with a spare disk and without a background initialization task. rcadm -C --raid1 --spare-disk 3 --disk 1 2 --no-sync Example: Print the maximum size a RAID5 array could be using all disks without actually creating the array. rcadm -C --raid5 --disk * --max-size 38
