Logical Volume Manager Considerations

> Logical Volume Manager Considerations

> Nytro XD does not support Logical Volume Manager (LVM). Nytro XD detects any attempt to add an LVM virtual disks either as a cache device or a VD, and fails the operation with a suitable error.Nytro XD also detects the presence of the LVM virtual disks on VDs, and restricts the user from configuring them with appropriate error messages and warnings. Specifically, Nytro XD detects the LVMs in these cases:

> • | un-partitioned VD under LVM control

> • | one or more partitions of VD under LVM control

> In either case, the corresponding VD cannot be configured in Nytro XD.

> For cache devices, Nytro XD detects the presence of the LVM virtual disks on the Nytro WarpDrive. However, it lets you forcefully add the corresponding Nytro WarpDrive as a cache device with the -force option (see Adding the Cache Devices). If the -force option is not used, Nytro XD restricts you from adding the cache device.
