Hi again,
I've made a fast translation into english of my howto.
Here is it
How to setup a Samba based cluster over RedHat EL3 with DRBD, HeartBeat and
Samba
- Install OS with default options plus development tools and kernel
development tools, setting then the server name.
- Modify /etc/inittab to set runlevel 3 (id:3:initdefault:)
- Download drbd-7.0.11.tar.gz from www.drbd.org to /root
- cd /usr/src/linux-2.4
- make mrproper
- cp /boot/config-2.4.21-20.Elsmp .config
- make –s oldconfig_nonint; make –s oldconfig_nonint
- make dep
- make include/linux/version.h
- cd /usr/src
- tar –xvzf /root/drbd-0.7.11.tar.gz
- cd drbd-0.7.11/drbd
- make clean all
- cd ../scripts
- make install
- edit /etc/drbd.conf to define mirrored resources
resource "r0" {
protocol C;
incon-degr-cmd "echo '!DRBD! pri on incon-degr' | wall ; sleep 60 ; halt
-f";
startup {
wfc-timeout 0; ## Infinite!
degr-wfc-timeout 120; ## 2 minutes.
}
disk {
on-io-error detach;
}
net {
}
syncer {
rate 50M;
group 1; # sync concurrently with r0
}
on pixie {
device /dev/drbd0;
disk /dev/hda6;
address 192.168.52.125:7789;
meta-disk internal;
}
on dixie {
device /dev/drbd0;
disk /dev/sda6;
address 192.168.52.126:7789;
meta-disk internal;
}
- cd ../drbd
- edit /etc/fstab to add new resources with option noauto
- chmod 744 drbd.o
- cp drbd.o /lib/modules/2.4.21-20.Elsmp/kernel/drivers/block
- edit /lib/modules/2.4.21-20.Elsmp/modules.dep and add reference to th
prevously copied driver module (drbd.o)
- cd /usr/src/drbd-0.7.11
- make tools
- make install-tools
- mknod /dev/drbd0 b 147 0 (repeat for each needed device)
- cd /etc/rc3.d
- ln –s ../init.d/drbd S93drbd
- ln –s ../init.d/drbd K93drbd
- Dowload hearbeat-pils, heartbeat-stonith y heartbeat, and install
them on this order
- Setup Samba
o cd /etc
o editar krb5.conf
§ default_realm = DOMAIN.NAME
§ [realms]
§ DOMAIN.NAME = {
§ kdc = server.domain.name:88
§ admin_server = server.domain.name:749
§ default_domain = domain.name
§ }
o editar nsswitch.conf
§ passwd files winbind
§ group files winbind
o editar samba/smb.conf
§ [global]
§ workgroup = WORKGROUPNAME
§ realm = DOMAIN.NAME
§ netbios name = NodeName
§ netbios aliases = ClusterName
§ winbind separator = /
§ idmap uid = 10000-20000
§ idmap gid = 10000-20000
§ winbind enum groups = yes
§ winbind enum users = yes
§ template homedir = /home/FOLDERNAME/%U
§ template shell = /bin/bash
§ server string = Server description
§ security = ADS
§ interfaces = cluster_ip_address/24
§ password server = server.domain.name
§ [SHARENAME]
§ comment = Description
§ path = /home/FOLDERNAME
§ writeable = yes
§ valid users = WORKGROUPNAME/Administrator
o create the shared folder (/home/FOLDERNAME)
o sync
o sync
o reboot
o kinit administrator at DOMAIN.NAME
o net ads join –U Adminstrator%administrator_password
o chown central/administrator /home/FOLDERNAME
- Setup heartbeat
o cd /etc/ha.d
o vi authkeys
§ auth 1
§ 1 crc
o vi ha.cf
§ node Node_A_Name
§ node Node_b_Name
§ deadtime 5
§ ucast eth0 (interface used by heartbeat) xx.xx.xx.xx (other node ip
address)
§ auto_failbak off
o vi haresources
§ servername_a ip.address/masklen drbddisk::r0 \
§ Filesystem::/dev/drbd0::/home::ext3::acl,usrquota,grpquota \
§ drbddisk::r1 \
§ Filesystem::/dev/drbd1::/home2::ext3::acl,usrquota,grpquota \
§ smb \
§ winbind
o chmod 600 /etc/ha.d/authkeys
- Replicate Samba UID Mapping
o On active node:
§ /etc/init.d/winbind stop
§ /etc/init.d/smb stop
§ mkdir /home/cachesamba
§ mv /var/cache/samba/* /home/cachesamba
§ ln –s /home/cachesamba /var/cache/samba
§ /etc/init.d/winbind start
§ /etc/init.d/smb start
o On passive node
§ rm –rf /var/cache/samba
§ ln –s /home/cachesamba /var/cache/samba

Stupid question: Do you have to compile and use the kernel? or is it just
the module that is compiled?

Hi Espen,
I've had the samp problem but I solved it adding a reference to the module
drbd.o into the /lib/modules/2.4.21-20.Elsmp/modules.dep file.
good luck
P.S. however I haven't been able to compile it for RedHat ES4 because I've
no kernel sources ¿?¿?¿?¿?¿?¿

Newbee question: After compiling on RH 3.0 ES modprobe do not find the
module. Any suggestions?
