已过传输的卷是否支持大型卷和文件？
适用场景
- ONTAP 9.12.1P2+
- 支持大卷
- 大文件支持
- 支持大型LUN
- 过渡后的卷
问题解答
是
- ONTAP 9.12.1P2及更高版本 支持300 TB灵活卷和FlexGroup成员。支持的最大文件/LUN大小也从16 TB增加到128 TB。
- 如果某个卷先前已从7-模式系统过渡、则 该卷还支持最大卷大小300 TB和文件/LUN大小128 TB。
- 对于已转换的卷，卷级别设置"filesys-size-fixed"将设置为"true "。 将此设置修改为"false"可增加卷大小。
sj-clus-01::> volume modify -volume datavol -filesys-size-fixed false
Volume modify successful on volume datavol of Vserver svm1.

- 升级ONTAP 9.12.1P2或更高版本后、可以使用volume Modify调整大于100 TB的卷大小和/或自动支持大于16 TB的文件和LUN。
sj-clus-01::>
sj-clus-01::> volume modify -volume datavol -size 200t
Warning: Either the specified volume size or maximum autosize is larger than 100 TB or you are setting is-large-size-enabled flag to true. This will result in the volume supporting larger size limits. The new limit on the size of the volume will be 300TB. The limit on the size of a file or LUN will be 128TB. If this volume will become the source of a SnapMirror relationship, creation of SnapMirror or FlexCache relationships is only supported with volumes that reside in clusters with an effective cluster version of 9.12.1 or later, because of incompatible size limits. Revert of the cluster to an earlier version is not supported when a volume supports larger size limits. All volumes must be 100 TB or less, have all files be 16TB or less, and have larger size limit support disabled prior to revert.

sj-clus-01::*> volume conversion start -volume datavol -foreground true
Warning: * After the volume is converted to a FlexGroup, it will not be possible to change it back to a flexible volume.
* Converting flexible volume "datavol" in Vserver "svm1" to a FlexGroup will cause the state of all Snapshot copies from the volume to be set to "pre-conversion". Pre-conversion Snapshot copies cannot be restored.
* The volume is nearly out of available space. Converting this volume to a FlexGroup might lead to "No space left on device" errors.
* Converting the volume to a FlexGroup will not add additional resources for capacity. After converting, use the "volume expand" command to add resources.
