We have a simple Samba share available on some systems sat behind a
pair of LVSs. The LVSs are running CentOS4 and the repackaged
Ultramonkey packages out of the CentOS Extras repository...
heartbeat-ldirectord-1.2.3.cvs.20050927-1.centos4
heartbeat-stonith-1.2.3.cvs.20050927-1.centos4
heartbeat-pils-1.2.3.cvs.20050927-1.centos4
heartbeat-1.2.3.cvs.20050927-1.centos4
The ldirectord.cf on the LVSs looks as follows...
# TEST SAMBA THROUGH TO DBVIP
virtual=192.168.24.45:137
real=192.168.25.10:137 masq
service=none
scheduler=rr
persistent=600
protocol=udp
# TEST SAMBA THROUGH TO DBVIP
virtual=192.168.24.45:138
real=192.168.25.10:138 masq
service=none
scheduler=rr
persistent=600
protocol=udp
# TEST SAMBA THROUGH TO DBVIP
virtual=192.168.24.45:139
real=192.168.25.10:139 masq
service=none
scheduler=rr
persistent=600
protocol=tcp
# TEST SAMBA THROUGH TO DBVIP
virtual=192.168.24.45:445
real=192.168.25.10:445 masq
service=none
scheduler=rr
persistent=600
protocol=tcp
The back-end boxes are FC3 running Ultramonkey packages again, and
DRBD for disk replication.
heartbeat-stonith-1.2.3-2.fr.c.1
heartbeat-pils-1.2.3-2.fr.c.1
heartbeat-1.2.3-2.fr.c.1
Samba startup is handled from /etc/ha.d/haresources by simply
including "smb" as a resource which starts/stops on failover. The
smb.conf's very simple too...
[global]
server string = Samba on %h
hosts allow = 192.168.24.
log file = /var/log/samba/%m.log
max log size = 5000
security = share
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
interfaces = 192.168.25.6/32 192.168.25.10/32
dns proxy = no
[ftp]
comment = Test FTP Homes
browseable = yes
writeable = yes
guest ok = yes
path = /mnt/sharedhomes/
This has been pretty reliable but it's not high volume by any stretch
of the imagination. Nor is it attached to a domain so I'm not sure how
you'll get on with browser mastering etc.
Will.
