How to grow vxfs directory but the server is in Veritas Cluster environment?
Hello,
Usually I use "vxresize" to grow vxfs directory in a stand-alone server without any problems, but I am just told to grow vxfs directorys in Veritas Cluster nodes.
Since I never done it before, would like to ask all the experts here to make sure the concept and steps will be fine before I pursue.
Example-1:
2 nodes cluster ( server-a and server-b ) in VCS control
Request: grow /opt/oracle with additional 10GB
What I notice is: the cluster is not using Veritas Cluster File System to mange its file systems =>
Which means, I can't grow file system in master node, then expect slave node will grow too .... I need to grow file systems separately on both cluster nodes --> is this concept correct?
server-a# df -h | grep /opt/oracle
/dev/vx/dsk/serveradg/optoracle 20G 13G 6.7G 66% /opt/oracle
server-b# df -h | grep /opt/oracle
/dev/vx/dsk/serverbdg/optoracle 20G 13G 6.8G 66% /opt/oracle
The reason I want to make sure is that I don't have clear Veritas Cluster knowledge, so I always thought that to grow filesystem in one node, the other nodes in the cluster should see the same change automatically, but while reasing online, I noticed this seems only works if file systems are under Veritas Cluster Filesystem control, so I would like to be careful before I go to run "vxresize" ... to prevent I am not going to mess up the cluster.
Can anyone help to share/confirm that I should still go to each node in the cluster to grow file systems even though those nodes are in the same cluster, but not in Veritas Cluster Filesystem control?
Thank you very much,
SC

vxbootsetup
vxbootsetup(1M) vxbootsetup(1M)
NAME
vxbootsetup - set up system boot information on a Veritas Volume Manager disk
SYNOPSIS
/etc/vx/bin/vxbootsetup [-g diskgroup] [medianame ... ]
DESCRIPTION
The vxbootsetup utility configures physical disks so that they can be used to boot the system. Before vxbootsetup is called to configure a
disk, the required volumes, standvol, rootvol and swapvol (and optionally, dumpvol) must be created on the disk. All of these volumes must
be contiguous with only one subdisk.
The -g option may be used to specify the boot disk group.
If no medianame arguments are specified, all disks that contain usable mirrors of the root, swap, /usr and /var volumes are configured to
be bootable.
If medianame arguments are given, only the disks that are associated with the specified disk names are configured to be bootable.
vxbootsetup requires that:
o The root volume must be named rootvol and must have a usage type of root.
o The swap volume must be named swapvol and must have a usage type of swap.
o The volumes containing /usr and /var (if any) must be named usr and var, respectively.
See the chapter "Recovery from Boot Disk Failure" in the Veritas Volume Manager Troubleshooting Guide for detailed information on how the
system boots and how VxVM impacts the system boot process. The vxmirror, vxrootmir, and vxresize utilities call vxbootsetup automatically.
If you use vxassist, or vxmake and vxplex to create mirrors of the root volume on a disk, you must run vxbootsetup explicitly to make the
disk bootable.
ARGUMENTS
medianame
Specifies the disk name (disk media name) of a VM disk that is to be configured as bootable.
