The Disk field specifies the maximum amount of disk space that the quota target can use. The value in this field represents a hard limit that cannot be exceeded.
The following list describes the rules for specifying a value in this field:
- You cannot leave the Disk field blank.
The value that follows the Type field is always assigned to the Disk field; thus, for example, Data ONTAP regards the following two quotas file entries as equivalent:
#Quota Target type disk files
/export tree 75K
/export tree 75K
- K means 1,024 bytes, M means 2 to the 20th power or 1024 * 1024 bytes, and G means 2 to the 30th power or 1024 * 1024 * 1024 bytes.
Note: The Disk field is not case-sensitive. Therefore, you can use K, k, M, m, G, or g.
- The maximum value you can enter in the Disk field is one of the following values (approximately equivalent to 1,023 PB):
- 1,073,741,823G
- 1,099,511,627,775M
- 1,125,899,906,842,620K
Note: If you omit the K, M, or G, Data ONTAP assumes a default value of K. The value cannot be specified in decimal notation.
- The value in the Disk field should be a multiple of 4 KB.
If it is not, the Disk field can appear incorrect in quota reports. This happens because the Disk field is always rounded up to the nearest multiple of 4 KB to match disk space limits, which are translated into 4-KB disk blocks.
- Your quota limit can be larger than the amount of disk space available in the volume.
In this case, a warning message is printed to the console when quotas are initialized.
- To apply a tracking quota (which tracks disk usage without imposing a limit), type a hyphen (-).
