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

Hi,
I have 2 hosts with Veritas VxVM and VxFS (5.0 MP3_RP2). I need to use the application filesystem's luns from these 2 hosts and mount it on another 2 hosts that are running Solaris 9 09/05 and SVM.
Is there resources online or has someone tried this? (0 Replies)

NAME
vxse - Storage Expert rules
SYNOPSIS
/opt/VRTS/vxse/vxvm/vxse_rule [-g diskgroup] [-d defaults_file] [-v] check
/opt/VRTS/vxse/vxvm/vxse_rule [-g diskgroup] [-d defaults_file] [-v] info
/opt/VRTS/vxse/vxvm/vxse_rule [-g diskgroup] [-d defaults_file] [-v] list
/opt/VRTS/vxse/vxvm/vxse_rule [-g diskgroup] [-d defaults_file] [-v] run [attribute=value...]
DESCRIPTION
Storage Expert consists of a set of simple commands that collects VxVM configuration data and compares it with "best practice." Storage
Expert then produces a summary report that shows which objects do not meet these criteria and makes recommendations for VxVM configuration
improvements.
These user-configurable tools help you as an administrator to verify and validate systems and non-optimal configurations in both small and
large VxVM installations.
Storage Expert components include a set of rule scripts and a rules engine. The rules engine runs the scripts and produces ASCII output,
which is organized and archived by Storage Expert's report generator. This output contains information about areas of VxVM configuration
that do not meet the set criteria. By default, output is sent to the screen, but you can redirect it to a file using standard UNIX redi-
rection.
KEYWORDS
check Lists the default values used by a rule's attributes.
info Describes what a rule does.
list Lists the attributes of a rule that can be set.
run Runs a rule. If one or more attribute-value pairs are specified, these override the values set in the defaults file.
OPTIONS
-d defaults_file
Specifies an alternate default attribute-values file to the standard file, /etc/default/vxse.
-g diskgroup
Specifies the disk group to be examined instead of the default disk group (see vxdg(1M)).
-v Specifies verbose output format.
EXAMPLES
Note: The executable rule files are located in the directory, /opt/VRTS/vxse/vxvm. These examples assume that this directory has been
added to the PATH variable.
Discover what the vxse_stripes2 rule does:
vxse_stripes2 info
Display the attributes that are available for the vxse_drl1 rule:
vxse_drl1 list
Display the default values of the attributes for the vxse_stripes2 rule:
vxse_stripes2 check
Run the vxse_volplex rule on the mydg disk group:
vxse_volplex -g mydg run
Run the vxse_drl2 rule on the mydg disk group with the value of the large_mirror_size attribute set to 30MB:
vxse_drl2 -g mydg run large_mirror_size=30m
Run the vxse_srl2 rule using the default attribute values that are set in the file mydefaultsfile:
vxse_drl2 -d mydefaultsfile -g mydg run
FILES
/etc/default/vxse Standard attribute values file for vxse rules.
/opt/VRTS/vxse/vxvm Directory containing executable rules.
NOTES
See the "Using Veritas Storage Expert" chapter in the Veritas Volume Manager Administrator's Guide for a description of the rules and their
attributes.
