buckets, and keys. A
1. Storage Space level quota
Administrators should be able to define how much storage space a Volume or
Bucket can use. The following Settings for Storage space quota are currently
supported：
+
a. By default, the quota for volume and bucket is not enabled.
+
b. When volume quota is enabled, the total size of bucket quota cannot exceed
volume.
+
c. Bucket quota can be set separately without enabling Volume quota. The size
of bucket quota is unrestricted at this point.
+
d. Volume quota is not currently supported separately, and volume quota takes
effect only if bucket quota is set. Because ozone only check the usedBytes of
the bucket when we write the key.
+e. If the cluster is upgraded from old version less than 1.1.0, use of quota
on older volumes and buckets is not recommended. Since the old key is not
counted to the bucket's usedBytes, the quota setting is inaccurate at this
point.
Review comment:
Currently, we have not agreed on whether bucket can be enabled for the
old quota. At present, we only put forward the suggestion in the document very
briefly. If the requirement is clear, we can issue Jira and solve it.
