gnt-job(8) Ganeti | Version 3.0.0

Name

gnt-job - Job commands

Synopsis

gnt-job {command} [arguments...]

DESCRIPTION

The gnt-job is used for examining and manipulating the job queue.

COMMANDS

ARCHIVE

archive {job-id...}

This command can be used to archive job by their IDs. Only jobs that have finished execution (i.e either success, error or canceled jobs).

AUTOARCHIVE

autoarchive {age | all}

Archive jobs by their age. This command can archive jobs older than age seconds, or alternatively all finished jobs can be archived if the string all is passed.

CANCEL

cancel
{[--force] [--kill] {--pending | --queued | --waiting} |
 *job-id* ...}

Cancel the job(s) identified by the given job id. Only jobs that have not yet started to run can be canceled; that is, jobs in either the queued or waiting state. To skip a confirmation, pass --force. --queued and waiting can be used to cancel all jobs in the respective state, --pending includes both.

If the --kill option is given, jobs will be killed, even if in running state, using SIGKILL in the latter case. This is dangerous, as the job will not have the chance to do any clean up; so it will most likely leave any objects it touched in an inconsistent state.

CHANGE-PRIORITY

change-priority --priority {low | normal | high}
{[--force] {--pending | --queued | --waiting} | job-id...}

Changes the priority of one or multiple pending jobs. Jobs currently running have only the priority of remaining opcodes changed. --priority must be specified. --queued and waiting can be used to re-prioritize all jobs in the respective state, --pending includes both. To skip a confirmation, pass --force.

INFO

info {job-id...}

Show detailed information about the given job id(s). If no job id is given, all jobs are examined (warning, this is a lot of information).

LIST

list [--no-headers] [--separator=*SEPARATOR*]
[-o [+]FIELD,...] [--filter] [job-id...]

Lists the jobs and their status. By default, the job id, job status, and a small job description is listed, but additional parameters can be selected.

The --no-headers option will skip the initial header line. The --separator option takes an argument which denotes what will be used between the output fields. Both these options are to help scripting.

The -o option takes a comma-separated list of output fields. The available fields and their meaning are:

archived

Whether job is archived

end_ts

Timestamp of job end (tuple containing seconds and microseconds)

id

Job ID

opend

List of opcode execution end timestamps

opexec

List of opcode execution start timestamps (after acquiring locks)

oplog

List of opcode output logs

oppriority

List of opcode priorities

opresult

List of opcodes results

ops

List of all opcodes

opstart

List of opcode start timestamps (before acquiring locks)

opstatus

List of opcodes status

priority

Current job priority (19 to -20)

received_ts

Timestamp of when job was received (tuple containing seconds and microseconds)

start_ts

Timestamp of job start (tuple containing seconds and microseconds)

status

Job status

summary

List of per-opcode summaries

If the value of the option starts with the character +, the new fields will be added to the default list. This allows one to quickly see the default list plus a few other fields, instead of retyping the entire list of fields.

To include archived jobs in the list the --archived option can be used.

The following options can be used to show only specific jobs:

--pending

Show only jobs pending execution.

--running

Show jobs currently running only.

--error

Show failed jobs only.

--finished

Show finished jobs only.

If exactly one argument is given and it appears to be a query filter (see ganeti(7)), the query result is filtered accordingly. For ambiguous cases (e.g. a single field name as a filter) the --filter (-F) option forces the argument to be treated as a filter.

LIST-FIELDS

list-fields [field...]

Lists available fields for jobs.

WAIT

wait {job-id}

Wait for the job by the given job-id to finish; do not produce any output.

WATCH

watch {job-id}

This command follows the output of the job by the given job-id and prints it.

REPORTING BUGS

Report bugs to the project's issue tracker or contact the developers using the Ganeti mailing list.
