Using vsftpd under Veritas VCS Application agent

Add a group

haconf -makerw
hagrp -add vsftpd_grp
hagrp -modify vsftpd_grp SystemList Node01 0 Node02 1
hagrp -autoenable vsftpd_grp -sys Node01
hagrp -autoenable vsftpd_grp -sys Node02
hagrp -modify vsftpd_grp OnlineRetryLimit 3
# start group on both nodes
hagrp -modify vsftpd_grp AutoFailOver 0
hagrp -modify vsftpd_grp Parallel 1

Add Resource

hares -add vsftpd_res Application vsftpd_grp
hares -modify vsftpd_res StartProgram "/etc/init.d/vsftpd start"
hares -modify vsftpd_res StopProgram  "/etc/init.d/vsftpd stop"
# if you want to run as root - ignore this line

hares -modify vsftpd_res User a_user_name

# command will be executed as su - a_user_name
hares -modify vsftpd_res UseSUDash 1                  
# Monitor process - whole string as appears in ps -ef output
hares -modify vsftpd_res MonitorProcesses \ 
   "/usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf"
# not tested
hares -modify vsftpd_res MonitorProgram "/etc/init.d/vsftpd status"
# does not write a pid file - ignore it
hares -modify vsftpd_res PidFiles "/var/run/vsftpd.pid"         
hares -modify vsftpd_res Enabled 1
# Make group dependendt on cluster filesystem (or any other group you wish)
hagrp -link vsftpd_grp CFS_Group online local firm
haconf -dump -makero

Bring vsftpd online

hagrp -online vsftpd_grp -sys Node01
hagrp -online vsftpd_grp -sys Node02

Snip from config file

group mq_group (
        SystemList = { Node01 = 0, Node02 = 1 }
        AutoFailOver = 0
        Parallel = 1
        AutoStartList = { Node01, Node02 }

Using bond interface for Veritas VCS LLT link

If you need to use bonded interface (say bond0) in Veritas VCS on linux, you may be getting jeopardy entries in gabconfig -a.


# gabconfig -a  ( on a three node cluster)

You need to change llttab like bellow ( see set-dbg-minlinks 2) and it will go off !

# cat /etc/llttab

set-node

set-cluster 59195

link bond0 bond0 - ether - -

set-verbose 1

set-dbg-minlinks 2

A good working gabconfig will loook like:

# gabconfig -a
