Hello,

Although I haven't received any feedback, but I would like to share what I have just completed on the server.

Request from DBA: to grow /opt/oracle in a 4-node Veritas Cluster.

My question: how do I grow vxfs file system in a VCS environment since it's not using Veritas Cluster Filesystem, I can't grow the file system in master node and see it grow in all 4 nodes.

What I was thinking:

(1) is /opt/oracle under VCS control?

=> I went to check Veritas Cluster configuration file in /etc/VRTSvcs/conf/config/main.cf , noticed there has no mount point /opt/oracle defined, which means this file system is not under VCS control.

(2) To make sure, I login to all 4 nodes and noticed /opt/oracle is created in different disk groups

(3) Try to make sure again, I checked the size of /opt/oracle on all 4 nodes, noticed they are in different size

Therefore, I concluded serverb:/opt/oracle is "stand-alone" in serverb, I should be able just use simple "vxresize" to grow the file system.

Note:

1. vxdiskadm -> to initiate the 2 new SAN disks into serverbdg on serverb
2. vxresize -F vxfs -g serverbdg optoracle +XXg newdisk1 newdisk2

vxinstall

vxinstall(1M)															     vxinstall(1M)

NAME

       vxinstall - menu-driven Veritas Volume Manager initial configuration procedure

SYNOPSIS

       vxinstall

DESCRIPTION

       The  vxinstall utility provides a menu driven interface to configure Veritas Volume Manager (VxVM).  If you install the Veritas Volume Man-
       ager software package using the operating system's package administration commands, you can run vxinstall to configure VxVM for initial use
       on your system.

       Note: If you use the Veritas software installation scripts, do not run this utility.

OPERATIONS

       Licensing
	    vxinstall  first asks if you want to view the Veritas licenses already installed on the system.  Answering "yes" is equivalent to exe-
	    cuting the vxlicrep command (see vxlicrep(1)).

	    You are then asked if you want to add licenses for other Veritas products.	Answering "yes" is equivalent  to  running  the  vxlicinst
	    command (see vxlicinst(1)).  and entering a license key.

       Enclosure-Based Naming
	    You  can choose whether you want to use disk access names that are based on the device names assigned by the operating system, or that
	    are based on names that you assign to enclosures.

       System-Wide Default Disk Group
	    You can enter the name for the default disk group (defaultdg).  This is an alias for the disk group name that should be assumed if the
	    -g	option is not specified to a command, or if the VXVM_DEFAULTDG environment variable is undefined.  By default, defaultdg is set to
	    nodg (that is, no disk group).

NOTES

       From release 4.0 of VxVM, it is no longer necessary to run vxinstall to configure the rootdg disk group.  Disks	and  disk  groups  may	be
       added  to  VxVM	by  running  commands such as vxdiskadm(1M) or by using the graphical user interface without first running vxinstall.  The
       operation of VxVM does not require any disk groups to have been configured, and a disk group named rootdg does not need to  be  present	on
       the system.  Any disk group may be configured as the default disk group that is to be used with VxVM commands.  Any disk group named rootdg
       has no special significance to VxVM. See the vxdg(1M) manual page for further details.
