##### Parameter 1: id

#### id

Type: integer

##### Parameter 2: options

#### options

Type: object Default: {}

Query options customize the results returned by a query method. More complete documentation with examples are covered in the "Query methods" section of the TrueNAS API documentation.

No Additional Properties

##

#### Extra

Type: object Default: {}

Extra options are defined on a per-endpoint basis and are described in the documentation for the associated query method.

##

#### Order By

Type: array of string Default: []

An array of field names describing the manner in which query results should be ordered. The field names may also have one of more of the following special prefixes: `-` (reverse sort direction), `nulls_first:` (place any null values at the head of the results list), `nulls_last:` (place any null values at the tail of the results list).

No Additional Items

##### Each item of this array must be:

Type: string
Example:

    [
        "size",
        "-devname",
        "nulls_first:-expiretime"
    ]

##

#### Select

Type: array Default: []

An array of field names specifying the exact fields to include in the query return. The dot character `.` may be used to explicitly select only subkeys of the query result.

##

#### Count

Type: boolean Default: false

Return a numeric value representing the number of items that match the specified `query-filters`.

##

#### Get

Type: boolean Default: false

Return the JSON object of the first result matching the specified `query-filters`. The query fails if there specified `query-filters` return no results.

##

#### Offset

Type: integer Default: 0

This specifies the beginning offset of the results array. When combined with the `limit` query-option it may be used to implement pagination of large results arrays. WARNING: some query methods provide volatile results and the onus is on the developer to understand whether pagination is appropriate for a particular query API method.

##

#### Limit

Type: integer Default: 0

This specifies the maximum number of results matching the specified `query-filters` to return. When combined wtih the `offset` query-option it may be used to implement pagination of large results arrays.

WARNING: Some query methods provide volatile results and the onus is on the developer to understand whether pagination is appropriate for a particular query API method.

##

#### Force Sql Filters

Type: boolean Default: false

Force use of SQL for result filtering to reduce response time. May not work for all methods.

#### KerberosRealmEntry

##

#### Id

Type: integer

Unique identifier for the Kerberos realm configuration.

##

#### Primary Kdc

Default: null

The master Kerberos domain controller for this realm. TrueNAS uses this as a fallback if it cannot get credentials because of an invalid password. This can help in environments where the domain uses a hub-and-spoke topology. Use this setting to reduce credential errors after TrueNAS automatically changes its machine password.

## Any of

Type: string

Must be at least `1` characters long

Type: null

##

#### Kdc

Type: array of string Default: []

List of kerberos domain controllers. If the list is empty then the kerberos libraries will use DNS to look up KDCs. In some situations this is undesirable as kerberos libraries are, for intance, not active directory site aware and so may be suboptimal.

##### Each item of this array must be:

Type: string

Must be at least `1` characters long

##

#### Admin Server

Type: array of string Default: []

List of kerberos admin servers. If the list is empty then the kerberos libraries will use DNS to look them up.
