=head1 NAME
B<updatenode> - Reruns postsctipts or runs additional scripts on the nodes.
=head1 B<NAME>
=head1 SYNOPSIS
I<updatenode [-h| --help]>
I<updatenode [-v| --version]>
I<updatenode I<noderange> [I<script1>[,I<script2>...]]>
B<updatenode> - Update nodes in an xCAT cluster environment.
=head1 DESCRIPTION
=head1 B<SYNOPSIS>
This command is used for the following:
1 install additional software for stateful nodes.
2 run postscripts defined in the postscripts table for both stateful and stateless nodes.
3 run any script for both stateful and stateless nodes.
B<updatenode> [-h|--help|-v|--version]
=head1 Parameters
B<updatenode> <noderange> [-V|--verbose] [-F|--sync] [-S|--sw]
[-P|--scripts [script1,script2...]]
I<noderange> is a list of nodes and node groups.
B<updatenode> <noderange> [-V|--verbose] [script1,script2...]
I<script1,script2...> a list of script names. The scripts must be copied under /install/postsctipts directory. They can be from the I<postsctipts> table or not.
=head1 OPTIONS
=head1 B<DESCRIPTION>
B<-h | --help> Display usage message.
The updatenode command is run on the xCAT management node and can be used
to perform the following node updates:
1) Distribute and synchronize files.
2) Install or update software on diskfull nodes.
3) Re-run postscripts.
B<-v | --version > Command Version.
The default behavior of updatenode will be to attempt to perform all three
types of updates. If you wish to limit updatenode to one or two specific
actions you can use combinations of the "-S", "-P", and "-F" flags.
=head1 RETURN VALUE
For example, If you just want to synchronize configuration file you could
specify the "-F" flag. If you want to synchronize files and update
software you would specify the "-F" and "-S" flags. See the descriptions
of these flags and examples below.
Note: In a large cluster environment the updating of nodes in an ad hoc
manner can quickly get out of hand, leaving the system administrator with
a very confusing environment to deal with. The updatenode command is
designed to encourage users to handle cluster updates in a manner that
is recorded and easily repeatable. If you are not concerned about the
structure the updatenode command provides you can use other xCAT support
such as xdsh and xdcp to accomplish these update tasks.
=head2 B<To distribute and synchronize files>
The basic process for distributing and synchronizing nodes is:
- Create a synclist file.
- Indicate the location of the synclist file.
- Run the updatenode command to update the nodes.
Files may be distributed and synchronized for both diskless and
diskfull nodes. However, since some filesystems are mounted
read-only on AIX diskless nodes it my not be possible to update all
files on AIX systems. For example, any files under /usr on AIX
diskless nodes cannot be updated.
More details for synchronization file is described "Sync-File HowTo".
Create the synclist file.
The synclist file contains the configuration entries that specify
where the files should be synced to. In the synclist file, each
line is an entry which describes the location of the source files
and the destination location for the files on the target node.
The basic entry format looks like following:
path_of_src_file1 -> path_of_dst_file1
path_of_src_file1 path_of_src_file2 ... ->
path_of_dst_directory
The path_of_src_file* should be the full path of the source file
on the Management Node.
The path_of_dst_file* should be the full path of the destination
file on target node.
The path_of_dst_directory should be the full path of the destina-
tion directory.
Since the synclist file is for common purpose, the target node
need not be configured in it, it will be the noderange input to
updatenode.
The following formats are supported:
1) sync file /etc/file1 to the directory /etc on the node with
the same file name
/etc/file1 -> /etc
2) sync file /etc/file2 to the file /etc/file2 on the node (with
same file name)
/etc/file2 -> /etc/file2
3) sync file /etc/file2 to the file /etc/file3 on the node (with
different file name)
/etc/file2 -> /etc/file3
4) sync the multiple files /etc/file1, /etc/file2, /etc/file3,
... to the directory /tmp/etc (/tmp/etc must be a directory when
multiple files are sync'd at one time). If the diretory does
not exist, xdcp will create it.
/etc/file1 /etc/file2 /etc/file3 -> /tmp/etc
Comment lines are NOT supported in the synlist file.
Indicate the location of the synclist file.
For Linux nodes.
The path of the synclist should be following format:
/install/custom/<inst_type>/<distro>/<profile>.<os>.<arch>.
synclist
<inst_type>: "install", "netboot"
<distro>: "rh", "centos", "fedora", "sles"
<profile>,<os> and <arch> are what you set for the node
For AIX nodes.
Add a full path of the synclist file to the "synclists"
attribute base on the xCAT osimage name used by the node
in the osimage table.
chdef -t osimage -o myosimage synclists=/mydir/syncfile1
Run updatenode to synchronize the files.
updatenode <noderange> -F
=head2 B<To install or update software (only available on Linux Nodes)>
The basic process for updating software on diskfull nodes is:
- Copy the software to a mountable directory.
- Create a record of what software to install.
- Run the updatenode command to update the nodes.
On Linux systems
To install additional software for Linux diskfull nodes,
First, copy the extra rpms you are going to add on to
/install/post/otherpkgs/<os>/<arch>/* directory where <os> and
<arch> are defined in the <nodetype> table.
Second, add rpm names (without version number) into
/install/custom/install/<ostype>/profile.otherpkgs.pkglist
where <profile> is defined in the <nodetype> table. <ostype>
is the operating system name without the version number.
The following os types are recognized by xCAT.
centos
fedora
rh
sles
windows
Third, type:
updatenode <noderange> -S
=head2 B<To re-run postscripts>
The scripts must be copied to the /install/postscripts
directory on the xCAT management node. (Make sure they are
executable.)
To run scripts on a node you must either specify them on the
command line or you must add them to the "postscripts" attribute
for the node.
To set the postscripts attribute of the node (or group)
definition you can use the xCAT chdef command. Set the value to
be a comma separated list of the scripts that you want to be
executed on the nodes. The order of the scripts in the list
determines the order in which they will be run. You could also set
the postscripts value by directly editing the xCAT "postscripts"
database table using the xCAT tabedit command.
Scripts may be run on both diskless and diskfull nodes.
To re-run all the customization scripts that have been designated
for the nodes, (in the "postscripts" attribute), type:
updatenode <noderange> -P
To re-run the "syslog" script for the nodes, type:
updatenode <noderange> -P syslog
To re-run a list of scripts, type:
updatenode <noderange> -P script1,script2
The flag '-P' is omitted when only postscripts parameters are
specified.
Note: script1,script2 may or may not be designated as a scripts to
automatically run on the node. However, if you want script1 and
script2 get invoked next time the nodes are deployed then make sure
to add them to the "postscripts" values for the nodes.
=head1 B<PARAMETERS>
<noderange> A set of comma delimited xCAT node names
and/or group names. See the xCAT "noderange"
man page for details on additional supported
formats.
<script1,script2...> A comma-separated list of script names.
The scripts must be executable and copied
to the /install/postscripts directory.
=head1 B<OPTIONS>
-F|--sync Specifies the file synchronization should be
performed on the nodes. rsync and ssh must
be installed and configured on the nodes.
-h|--help Display usage message.
-P|--sw Specifies that node software should be updated.
-S|--scripts Specifies that postscripts should be run on the nodes.
-v|--version Command Version.
-V|--verbose Verbose mode.
=head1 B<RETURN VALUE>
0 The command completed successfully.
1 An error has occurred.
=head1 EXAMPLES
1. To install additional software for Linux stateful nodes, first copy the extra rpms you are going to add on to
=head1 B<EXAMPLES>
/install/post/otherpkgs/<os>/<arch>/*
1) To perform all updatenode features for the Linux nodes in the group
"compute".
updatenode compute
directory where <os> and <arch> are defined in the I<nodetype> table.
The command will: run any scripts listed in the nodes "postscripts"
attribute, install or update any software indicated in the
/install/custom/install/<ostype>/profile.otherpkgs.pkglist (refer to the
B<To install or update software part>), synchronize any files indicated by
the synclist files specified in the osimage "synclists" attribute.
Second, add rpm names (without version number) into
2) To perform a software update and file synchronization only on the node
"clstrn01".
updatenode clstrn01 -F -P
/install/custom/install/<ostype>/profile.otherpkgs.pkglist
3) To re-run the postscripts which indicated in the postscripts attribute on
the node "clstrn01".
updatenode clstrn01 -P
where <profile> is defined in the I<nodetype> table. <ostype> is the operating system name without the version number. The following os types are recognized by xCAT.
4) To re-run the postscripts script1 and script2 on the node "clstrn01".
Copy these scripts to the /install/postscripts first.
updatenode clstrn01 -P script1,script2
Since flag '-P' is omitted when only postscripts parameters are specified,
the following command line are equivalent.
updatenode clstrn01 script1,script2
centos
fedora
rh
sles
windows
5) To synchronize the files on the node "clstrn01". Prepare the synclist file.
For AIX node, set the full path of synclist in the osimage table synclists
attribute. For Linux node, put the synclist file into the location:
/install/custom/<inst_type>/<distro>/<profile>.<os>.<arch>.synclist
updatenode clstrn01 -F
Third, type:
updatenode <noderange> otherpkgs
2. To re-run all the postscripts for the nodes, type
updatenode <noderange>
3. To re-run the syslog postscripts for the nodes, type
updatenode <noderange> syslog
4. To run a list of scripts, make sure the scripts are copied to /install/postscripts directory, then type
updatenode <noderange> script1,script2
Note: script1,script2 may or may not be defined in the postscripts table. However if you want script1 and script2 get invoked next time the nodes are deployed, add them into the postscripts table.
6) To perform the software update on the Linux node "clstrn01". Copy the extra
rpm into the /install/post/otherpkgs/<os>/<arch>/* and add the rpm names into
the /install/custom/install/<ostype>/profile.otherpkgs.pkglist
updatenode clstrn01 -S
