NAME
arcmigrate - ARC Migration
DESCRIPTION
The arcmigrate command is used for migrating queued jobs from one cluster to another cluster. Currently migration only works between clusters running A-REX.
SYNOPSIS
arcmigrate [options] [jobid ...]
OPTIONS
- -c, --cluster=[-]name
- explicitly select or reject a specific cluster holding queued jobs
- -q, --qluster=[-]name
- explicitly select or reject a specific cluster which queued jobs should/shouldn't be migrated to
- -i, --index=[-]name
- explicitly select or reject an index server
- -j, --joblist=filename
- file where the jobs will be stored
- -a, --all
- all jobs specified in the jobfile will be tried migrated
- -f, --forcemigration
- force migration, ignore kill failure
- -t, --timeout=seconds
- timeout in seconds (default 20)
- -z, --conffile=filename
- configuration file (default ~/.arc/client.conf)
- -d, --debug=debuglevel
- FATAL, ERROR, WARNING, INFO, VERBOSE or DEBUG
- -b, --broker
- selected broker (default Random)
- -v, --version
- print version information
- -?, --help
- print help
ARGUMENTS
- jobid ...
- id of a queued job which should be migrated
EXTENDED DESCRIPTION
The arcmigrate command is used for migrating jobs which are queuing in the batch system. Currently only jobs having status Queuing can be migrated, and the command is only supported for migration between clusters running A-REX.
The --qluster option can be used to force the job to be migrated to a particular cluster, or to reject migration to a particular cluster. The --qluster option can be repeated several times. The name of the cluster should be given in the format
ARC1:protocol://hostname[:port]/path
Examples:
- arcmigrate -q ARC1:https://knowarc1.grid.niif.hu:60000/arex ...
- will migrate a to knowarc1.grid.niif.hu.
- arcmigrate -q -ARC1:https://knowarc1.grid.niif.hu:60000/arex ...
- will migrate a job to some other cluster than knowarc1.grid.niif.hu.
Jobs to be migrated can be specified in serveral ways. Job IDs can be specified as arguments on the command line, clusters holding queued jobs can be specified with the --cluster option, and to migrate all jobs in the jobfile the --all option can be given.
If the job(s) is successfully migrated a jobid(s) is printed to stdout. This jobid uniquely identifies the job while it is being executed.
Information about active jobs, including the old job id of the migrated job, are stored in a local joblist file. By using the --joblist option a customized location for this file can be defined. If this option is used when migrating a job using arcmigrate, the same joblist file must be specified using the --joblist option for all subsequent handling of the job using arcstat(1), arcget(1), etc.
The arcmigrate command locates the available clusters by querying information index servers. Which servers to query can be specified by giving the --index option to the command. The name of the index server should be given in the format
Flavor:protocol://hostname[:port]/path
Example:
- arcmigrate -i ARC0:ldap://index1.nordugrid.org:2135/Mds-Vo-name=NorduGrid,o=grid ...
- use the NorduGrid index at index1.nordugrid.org
- arcmigrate -i -ARC0:ldap://grid.tsl.uu.se:2135/Mds-Vo-name=Sweden,o=grid ...
- do not use the Sweden index at grid.tsl.uu.se
FILES
- ~/.arc/client.conf
- Some options can be given default values by specifying them in the ARC client configuration file. By using the --conffile option a different configuration file can be used than the default.
- ~/.arc/jobs.xml
- This a local list of the user's active jobs. When a job is successfully migrated the old jobid is removed and the new is added to this list. This list is used as the list of all active jobs when the user specifies the --all option to the various NorduGrid ARC user interface commands. By using the --joblist option a different file can be used than the default.
ENVIRONMENT VARIABLES
- X509_USER_PROXY
- The location of the user's grid proxy file. Shouldn't be set unless the proxy is in a non-standard location.
- ARC_LOCATION
- The location where ARC is installed can be specified by this variable. If not specified the install location will be determined from the path to the command being executed, and if this fails a WARNING will be given stating the location which will be used.
- ARC_PLUGIN_PATH
- The location of ARC plugins can be specified by this variable. Multiple locations can be specified by separating them by : (; in Windows). The default location is $ARC_LOCATION/lib/arc (\ in Windows).
