Description Cordoning drives makes them unschedulable. Volume Manager does not schedule volumes on drives that have been cordoned. Use kubectl directpv uncordon to make cordoned drives accessible for scheduling again. Syntax kubectl directpv cordon [DRIVE ...] [flags] Parameters kubectl directpv cordon requires a way to define the drive(s) to cordon. The command does not require any specific parameter. All parameters are optional, as long as you include a way to select one or more drives in the command.

Updating Custom Installations Custom installations do not support client-side upgrade functionality. Use kubectl directpv migrate to migrate the old resources to a new installation. Pod Security Policies Kubernetes deprecated the PodSecurityPolicy feature in v1.21, then removed it entirely in v1.25. Use Pod Security Admission as a replacement, as recommended in the Kubernetes documentation.

Description Use this command to discover the block devices present in the cluster. The command outputs a yaml file listing the available drives. After generating the yaml, modify the file to select the drive(s) you wish to use with Volume Manager. Ensure that any drives that should not be erased by Volume Manager have not been selected in the yaml file.

A macro for defining `#[cfg]` match-like statements.

This macro handles automatic differentiation. Automatic Differentiation macro which allows generating a new function to compute the derivative of a given function. It may only be applied to a function. The expected usage syntax is `#[autodiff(NAME, MODE, INPUT_ACTIVITIES, OUTPUT_ACTIVITY)]` where: NAME is a string that represents a valid function name. MODE is any of Forward, Reverse, ForwardFirst, ReverseFirst. INPUT_ACTIVITIES consists of one valid activity for each input parameter. OUTPUT_ACTIVITY must not be set if we implicitly return nothing (or explicitly return `-> ()`). Otherwise it must be set to one of the allowed activities.

Bitwise and with the current value, returning the previous value. `T` must be an integer or pointer type. If `T` is a pointer type, the provenance of `src` is ignored: both the return value and the new value stored at `*dst` will have the provenance of the old value stored there.

Stores a value if the current value is the same as the `old` value. `T` must be an integer or pointer type.
