Display kernel coredump status

Availability: This command is available to cluster administrators at the admin privilege level.

Description

The system node coredump status command displays status information about core dumps. The command output depends on the parameters specified with the command. If a core dump is in the process of being saved into a core file, the command also displays its name, the total number of blocks that are to be saved, and the current number of blocks that are already saved.

You can specify additional parameters to display only information that matches those parameters. For example, to display coredump status information about the local node, run the command with the parameter -node local .

Parameters

{ [-fields <fieldname>,…​]

If you specify the -fields <fieldname>, …​ parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.

| [-disks ]

If you specify this parameter, the command displays the following information:

  • Node name

  • Total number of disks

  • Number of spare disks

  • Number of disks used

  • Number of disks with partial cores

| [-spraycore ]

If you specify this parameter, the command displays the following information:

  • Node name

  • Whether spray cores are supported

  • Number of spray-core disks

  • Number of spray-core blocks

  • Number of disks needed for spray core

  • Estimated number of blocks needed for spray core

| [-instance ] }

If you specify the -instance parameter, the command displays detailed information about all fields.

[-node {<nodename>|local}] - Node

If you specify this parameter, the command displays the following information:

  • Node name

  • State of the core-dump process

  • Space available on the internal file system

  • Name of the core being saved, if applicable

  • Total number of blocks in the core being saved, if applicable

  • Number of blocks currently saved, if applicable

  • Type of core dump

  • Number of unsaved complete cores on the node

  • Number of unsaved partial cores on the node

  • Whether spray cores are supported on the node

  • Whether any spare disks are available on the node

  • Number of disks that have cores

  • Number of unsaved cores

  • Number of disks that have partial cores

  • Number of partial cores

  • Number of unused spray-core disks

  • Number of spray-core blocks

  • Number of disks available for core dumps

  • Estimated number of blocks needed for spray core

  • Number of disks needed for spray core

[-state <text>] - State

If you specify this parameter, the command displays information only about the nodes that are in the specified core dump state. Possible values include: nocore, idle, init, saving, and waitdump.

[-space-available {<integer>[KB|MB|GB|TB|PB]}] - Space Available On Internal Filesystem

If you specify this parameter, the command displays information only about the nodes that have the specified amount of available space, in bytes, on their internal file systems.

[-corename <text>] - Name of Core Being Saved

If you specify this parameter, the command displays information only about the node that is currently saving the specified core file name.

[-total-blocks <integer>] - Total Number of Blocks in Core Being Saved

If you specify this parameter, the command displays information only about the nodes that have the specified number of blocks in the core dump being saved.

[-blocks-saved <integer>] - Number of Blocks saved

If you specify this parameter, the command displays information only about the nodes that have the specified number of blocks saved.

[-type <text>] - Type of Core Dump

If you specify this parameter, the command displays information only about the nodes that have the specified core dump type. Possible values include zipped, sprayed, and spare.

[-spraycore-supported {true|false}] - Spray Core Supported on Node

If you specify this parameter, the command displays information only about the nodes that do or do not support the spray method of dumping core.

[-spares-available {true|false}] - Spare Disk(s) Available on Node

If you specify this parameter, the command displays information only about the nodes that do or do not have spare disks available.

[-disks-used <integer>] - Number of Disks with Cores

If you specify this parameter, the command displays information only about the nodes that have the specified number of disks that contain core dumps.

[-unsaved-cores <integer>] - Number of Unsaved Complete Cores

If you specify this parameter, the command displays information only about the nodes that have the specified number of complete core dumps that are not yet saved into a core file.

[-partial-disks <integer>] - Number of Disks with Partial Cores

If you specify this parameter, the command displays information only about the nodes that have the specified number of disks with partial core dumps.

[-partial-cores <integer>] - Number of Unsaved Partial Cores

If you specify this parameter, the command displays information only about the nodes that have the specified number of partial core dumps that are not yet saved into a core file.

[-spraycore-disks <integer>] - Number of Unused Spray Core Disks

If you specify this parameter, the command displays information only about the nodes that have the specified number of spray-core blocks.

[-numdisks <integer>] - Total Number of Disks Available for Core Dump

If you specify this parameter, the command displays information only about the nodes that have the specified total number of disks available for core dump.

[-blocks-needed <integer>] - Estimated Number of Blocks Needed for Spray Core

If you specify this parameter, the command displays information only about the nodes that have the specified number of estimated blocks needed for the spray method of dumping core.

[-disks-needed <integer>] - Number of Disks Needed for Spray Core

If you specify this parameter, the command displays information only about the nodes that have the specified number of disks needed for the spray method of dumping core.

[-space-needed {<integer>[KB|MB|GB|TB|PB]}] - Space Needed to Save All Unsaved Cores

If you specify this parameter, the command displays information only about the nodes that require the specified amount of disk space to save all unsaved core dumps.

[-min-free {<integer>[KB|MB|GB|TB|PB]}] - Minimum Free Bytes on Root Filesystem

If you specify this parameter, the command displays information only about the nodes that need to have the specified number of bytes available on the root filesystem after a core dump is saved.
