NAME¶

opauploadall

(Linux) Copies one or more files from a group of hosts to this system. Since the file name is the same on each host, a separate directory on this system is created for each host and the file is copied to it. This is a convenient way to upload log files or configuration files for review. This tool can also be used in conjunction with opadownloadall to upload a host specific configuration file, edit it for each host, and download the new version to all the hosts.

NOTE: To copy files from this host to hosts in the cluster, use opascpall or opadownloadall. user@ style syntax cannot be used when specifying filenames.

Syntax¶

opauploadall [-rp] [-f hostfile] [-d upload_dir] [-h 'hosts'] [-u user] source_file ... dest_file

Options¶

--help

Produces full help text.

-p

Performs copy in parallel on all hosts.

-r

Performs recursive upload of directories.

-f hostfile

Specifies the file with hosts in cluster.
Default is /etc/opa/hosts file.

-h hosts

Specifies the list of hosts to upload from.

-u user

Specifies the user to perform copy to. Default is current user code.

-d upload_dir

Specifies the directory to upload to. Default is uploads. If not specified, the environment variable UPLOADS_DIR is used. If that is not exported, the default, /uploads, is used.

source_file

Specifies the name of files to copy to this system, relative to the current directory. Multiple files may be listed.

dest_file

Specifies the name of the file or directory on this system to copy to. It is relative to upload_dir/HOSTNAME .A local directory within upload_dir/ is created for each hostname.

Each uploaded file is copied to upload_dir/HOSTNAME/dest_file within the local system.

If more than one source file is specified or dest_file has a trailing / , a dest_file directory will be created.

Example¶

# upload two files from 2 hosts

opauploadall -h 'arwen elrond' capture.tgz /etc/init.d/ipoib.cfg.

# upload two files from all hosts

opauploadall -p capture.tgz /etc/init.d/ipoib.cfg.
