The space guarantee setting determines how much space is reserved in the aggregate for the volume. A space guarantee of “none” means that no space is reserved for the volume, and the volume can use any available space in the aggregate. This approach to space management is called thin provisioning. This setting would prevent the hosting aggregates from showing a decrease in available space when creating new volumes, as long as the aggregate is not overcommitted. References :- How volume guarantees work with FlexVol volumes, How you set space guarantees for new or existing volumes, What is the impact of changing volume space-guarantee from “volume” to “none”?

 To make the destination NAS volume writable, you need to break the SnapMirror relationship using the snapmirror break command from the destination cluster, and then use the volume mount command to mount the NAS volume in the NFS namespace. Breaking the SnapMirror relationship will make the destination volume read/write and allow clients to access the latest Snapshot copy. Mounting the volume in the NFS namespace will make the volume visible to the clients and enable them to access the data. The other options are not correct because:

• Deleting the SnapMirror relationship from the destination cluster will not make the destination volume writable, but rather remove the relationship configuration and history. This will prevent future resynchronization or updates of the relationship.
• Breaking the SnapMirror relationship using the snapmirror break command from the source cluster will not work, because the source cluster is unavailable due to networking issues. The command must be run from the destination cluster. References :- Break the SnapMirror relationship, Mount a volume in the namespace

 To find the highest latency seen on restore, you need to look at the output of the table that shows the latency measurements for different operations and sizes. The highest latency is 10021 ms, which is the maximum latency for the GET operation with 8KB size. This means that when the users recover files with the Windows Previous Versions tab, they are reading data from the cloud tier that has been tiered using the snapshot-only policy, which causes high latency and slow restores.

• The other latencies are not correct, as they are lower than 10021 ms. The maximum latency for the PUT operation with 4MB size is 10500 ms, but this is not related to the restore operation, as it is writing data to the cloud tier. The maximum latency for the GET operation with 4KB size is 9591 ms, which is slightly lower than 10021 ms. The maximum latency for the GET operation with 32KB size is 7889 ms, which is much lower than 10021 ms. The maximum latency for the GET operation with 256KB size is 7838 ms, which is also much lower than 10021 ms. References :- FabricPool overview, FabricPool requirements, FabricPool best practices, High READ Latency from the fabric pool aggregate.
