Upgrade to 2.5.0

[Joe Donner]

Dear all,

does anyone have any recent experience with upgrading amanda 2.4.4p1-0.3E.1 to 2.5.0 (Redhat ES 3)?

Any information on whether there are things to look out for will be much appreciated!

Thanks.

Use this command to find where the old installation directories and files are located:
-bash-3.00$ amadmin x version

Look for and take note of these directory paths in the amanda.conf file:

logdir "/var/lib/amanda/test"
infofile "/var/lib/amanda/test/curinfo"
indexdir "/var/lib/amanda/test/index"
tapelist "/var/lib/amanda/test/tapelist"

Find out where the amanda home directory is located:

-bash-3.00$ cat /etc/passwd | grep amanda
amanda:x:33:6:Amanda user:/var/lib/amanda:/bin/bash

Make a list of all the amanda directories and files that will be affected on the upgrade:

bindir /usr/bin
sbindir /usr/sbin
libexecdir /usr/lib/amanda
AMANDA_DBGDIR /var/log/amanda
CONFIG_DIR /etc/amanda
listed_incr_dir /var/lib/amanda/gnutar-lists
logdir /var/lib/amanda/test
infofile /var/lib/amanda/test/curinfo
indexdir /var/lib/amanda/test/index
tapelist /var/lib/amanda/test/tapelist
tapedev file:/space/vtapes/test/slots
changerfile /var/lib/amanda/test/changerfile
holding disk path /space/amandahold/test

Remove the old user amanda from the passwd and shadow files:

[root@vmservercomm ~]# cat /etc/passwd | grep amanda
amanda:x:501:6::/var/lib/amanda:/bin/bash
[root@vmservercomm ~]# cat /etc/shadow | grep amanda
amanda:!!:13276:0:99999:7:::

Remove the old user amanda from the group disk in /etc/group file:

disk:x:6:root,amanda

Create a temporary directory called /amandamove for amanda files to to copied to while upgrading:

mkdir /amandamove

Tar up the files and dirs containing the logs, curinfo, indexdir and tapelist in to the /amandamove directory:

[root@vmredhatserver tmp]# cd /var/lib/amanda
[root@vmredhatserver amanda]# tar -cvf /amandamove/index_curinfo.tar *

DailySet1/index/
test/
test/amdump.1

test/curinfo/vmredhatclient.zmanda.com/_boot/
test/curinfo/vmredhatclient.zmanda.com/_boot/info
test/tapelist.yesterday
test/changerfile-clean

Tar up the files and dirs containing all the amanda config files in to the /amandamove directory:

[root@vmredhatserver amanda]# cd /etc/amanda
[root@vmredhatserver amanda]# tar -cvf /amandamove/amanda_config.tar *
crontab.sample
DailySet1/
DailySet1/disklist
DailySet1/amanda.conf
test/
test/disklist
test/amanda.conf

Copy the /var/lib/amanda/.amandahosts to /amandamove:

[root@vmredhatserver amanda]# cp /var/lib/amanda/.amandahosts /amandamove

Determine what amanda rpm packages are already installed:

[root@vmredhatserver ppragin]# rpm -q amanda
amanda-2.4.5-2
[root@vmredhatserver ppragin]# rpm -q amanda-server
amanda-server-2.4.5-2
[root@vmredhatserver ppragin]# rpm -q amanda-client
package amanda-client is not installed

Unistall the original Redhat amanda rpm:

[root@vmredhatserver ppragin]# rpm -e amanda-server-2.4.5-2
warning: /etc/xinetd.d/amidxtape saved as /etc/xinetd.d/amidxtape.rpmsave
warning: /etc/xinetd.d/amandaidx saved as /etc/xinetd.d/amandaidx.rpmsave
[root@vmredhatserver ppragin]# rpm -e amanda-2.4.5-2
warning: /var/lib/amanda/.amandahosts saved as /var/lib/amanda/.amandahosts.rpmsave
[root@vmredhatserver ppragin]#

Remove the old amanda xinetd files:

[root@vmredhatserver xinetd.d]# cd /etc/xinetd.d
[root@vmredhatserver xinetd.d]# ls -al | grep am
-rw-r--r-- 1 root root 229 May 10 09:44 amandaidx.rpmsave
-rw-r--r-- 1 root root 232 May 10 09:44 amidxtape.rpmsave
[root@vmredhatserver xinetd.d]# rm amandaidx.rpmsave amidxtape.rpmsave
rm: remove regular file `amandaidx.rpmsave'? y
rm: remove regular file `amidxtape.rpmsave'? y
[root@vmredhatserver xinetd.d]#

Remove the old amanda directories:

[root@vmredhatserver /]# rm -rf /var/lib/amanda
[root@vmredhatserver /]# rm -rf /etc/amanda
[root@vmredhatserver /]# rm -rf /var/log/amanda

Install the amanda enterprise rpm:

[root@vmredhatserver server]# rpm -ih amanda_enterprise-backup_server-2.5.0-1.fc4.i386.rpm

Extract the amanda config files from /amandamove in to /etc/amanda:

[root@vmredhatserver amanda]# cd /etc/amanda
[root@vmredhatserver amanda]# tar -vxf /amandamove/amanda_config.tar
crontab.sample
DailySet1/
DailySet1/disklist
DailySet1/amanda.conf
test/
test/disklist
test/amanda.conf

Extract the amanda logs, curinfo, indexdir and taplist from /amandamove in to /usr/lib/amanda:

[root@vmredhatserver amanda]# cd /var/lib/amanda
[root@vmredhatserver amanda]# tar -vxf /amandamove/index_curinfo.tar

DailySet1/index/

test/amdump.1

test/curinfo/vmredhatclient.zmanda.com/_boot/

test/changerfile-clean

Copy the .amandahost file from /amandamove to the /var/lib/amanda directory:

[root@vmredhatserver amanda]# cp /amandamove/.amandahosts /var/lib/amanda/
cp: overwrite `/var/lib/amanda/.amandahosts'? y

Change onwership on the following amanda directories:

[root@vmredhatserver amanda]# chown -R amandabackup:disk /var/lib/amanda
[root@vmredhatserver amanda]# chown -R amandabackup:disk /etc/amanda
[root@vmredhatserver amanda]# chown -R amandabackup:disk /space

Edit the /var/lib/amanda/.amandahosts file and chnage all the amanda user entries to amandabackup:

vmredhatclient.zmanda.com root
vmredhatclient.zmanda.com amandabackup

Edit the amanda.conf file in /etc/amanda/test/amanda.conf and change the user entry from amanda to amandabackup:

dumpuser "amandabackup"

I wanted to make a small correction. The last post talks about installing the enterprise rpm, but you need to download the last community Amanda 2.5.0p2 Stable Release at http://zmanda.com/downloads.html . The upgrade process wil be the same. Feel free to contact me if you have any more questions.
Thanks

Wow - what a reply! I'm very much impressed :D

Thanks very much. I will run this through a test lab and see how it goes.
