When you create a default tree quota on a FlexVol volume, corresponding derived tree quotas are automatically created for every qtree in that volume.
These derived tree quotas have the same limits as the default tree quota. If no additional quotas exist, the limits have the following effects:
The existence of a default tree quota on a volume continues to affect all new qtrees that are added to the volume. Each time a new qtree is created, a derived tree quota is also created.
Like all derived quotas, derived tree quotas display the following behaviors:
----Disk---- ----Files----- Quota Volume Tree Type ID Used Limit Used Limit Specifier ------- -------- ------ ------- ----- ----- ------ ------ --------- vol1 proj1 tree 1 0B 10GB 1 - proj1 vol1 tree * 0B 20GB 0 - * vol1 proj2 tree 2 0B 20GB 1 - proj2 vol1 proj3 tree 3 0B 20GB 1 - proj3 ...The first line shows the original explicit quota on the proj1 qtree. This quota remains unchanged.
The second line shows the new default tree quota on the volume. The asterisk (*) Quota Specifier indicates it is a default quota. This quota is a result of the quota rule that you created.
The last two lines show new derived tree quotas for the proj2 and proj3 qtrees. Data ONTAP automatically created these quotas as a result of the default tree quota on the volume. These derived tree quotas have the same 20-GB disk limit as the default tree quota on the volume. Data ONTAP did not create a derived tree quota for the proj1 qtree because the proj1 qtree already had an explicit quota.
