| <p>目前,我们知道Ozone允许用户创建Volume,Bucket和Key。一个Volume通常包含几个Bucket,每个Bucket也包含一定数量的Key。显然,它应该允许用户定义配额(例如,在一个Volume下可以创建多少个Bucket或一个Bucket可以使用多少空间),这是存储系统的常见要求。</p> |
| <h2 id="目前支持的">目前支持的</h2> |
| <ol> |
| <li>Storage space级别配额</li> |
| </ol> |
| <p>管理员应该能够定义一个Volume或Bucket可以使用多少存储空间。目前支持以下storage space quota的设置:</p> |
| <p>a. 默认情况下volume和bucket的quota不启用。</p> |
| <p>b. 当volume quota启用时,bucket quota的总大小不能超过volume。</p> |
| <p>c. 可以在不启用volume quota的情况下单独给bucket设置quota。此时bucket quota的大小是不受限制的。</p> |
| <p>d. 目前不支持单独设置volume quota,只有在设置了bucket quota的情况下volume quota才会生效。因为ozone在写入key时只检查bucket的usedBytes。</p> |
| <p>e. 如果集群从小于1.1.0的旧版本升级而来,则不建议在旧volume和bucket(可以通过查看volume或者bucket的info确认,如果quota值是-2,那么这个volume或者bucket就是旧的)上使用配额。由于旧的key没有计算到bucket的usedBytes中,所以此时配额设置是不准确的。</p> |
| <p>f. 如果volume quota被启用,那么bucket quota将不能被清除。</p> |
| <ol start="2"> |
| <li>命名空间配额</li> |
| </ol> |
| <p>管理员应当能够定义一个Volume或Bucket可以使用多少命名空间。目前支持命名空间的配额设置为:</p> |
| <p>a. 默认情况下volume和bucket的命名空间配额不启用(即无限配额)。</p> |
| <p>b. 当volume命名空间配额启用时,该volume的bucket数目不能超过此配额。</p> |
| <p>c. 当bucket的命名空间配额启用时,该bucket的key数目不能超过此配额。</p> |
| <p>d. Linked bucket不消耗命名空间配额。</p> |
| <p>e. 如果集群从小于1.1.0的旧版本升级而来,则不建议在旧volume和bucket(可以通过查看volume或者bucket的info确认,如果quota值是-2,那么这个volume或者bucket就是旧的)上使用配额。由于旧的key没有计算到bucket的命名空间配额中,所以此时配额设置是不准确的。</p> |
