Restarting failed Avamar grid installation

Question

Hi!

I am trying to install brand new Avamar grid. It consists of 3 DS and 1 Utility. Dpnnetutil worked OK. The I started avqinstall. All went well, but at some point it fails. Now I am trying to run it again, but get: 2011/02/25-15:02:35 avqinstall: ERROR: to continue would wipe out existing backup data - perhaps you meant to apply a server software upgrade instead of a first-time installation?

Now the question is: how to revert Avamar grid to the state before installation so I can restart avqinstall? Or how to tell avqinstall to ignore/delete existing data?

hello,

> ERROR: gsan is running: do shutdown first, stopped at /usr/local/avamar/bin/dpn.pm line 3147.

Please load admin keys (described below), and use mapall command and kill all gsan ... and re-run comand

# mapall "killall gsan"

To run a command as user admin, load the admin SSH keys:
# su – admin
# ssh-agent bash
# ssh-add ~/.ssh/admin_key
Supply the admin key passphrase when prompted.

regards,

SOLUTION

ERROR:
n/a

SYMPTOM:
Customer wishes to remove all data from an Avamar system and start again

CAUSE:
n/a

RESOLUTION:

1) Shutdown the Avamar software
- dpnctl stop

2) Remove all data. It is VERY important that these EXACT commands be followed. Removing any additional data will make it very tough to recover without re-kickstarting.

- Log in as dpn
- Load dpn?s keys (ssh-agent bash; ssh-add ~/.ssh/dpnid)
- export SYSPROBEUSER=root
- mapall --noerror --parallel ?rm -rf /data0?/cur*?
- mapall --noerror --parallel ?rm -rf /data0?/cp*?
- mapall --noerror --parallel ?rm -rf /data0?/hfscheck*?
- mapall --noerror --parallel ?rm -rf /data0?/QA*?

3) Confirm all directories are empty
- mapall df -h
- ensure all partitions on every node are at ~33MB, with the exception of /data01. /data01 should be closer to 100MB

Once these steps have been done, the system has been wiped clean.

If you want to start the software back up you need to re-install Avamar using the avw_install process again. When running avw_install you absolutely *must* pay attention to any problems it throws up and solve them before moving onto the next step.

**NOTE** If you wish to wipe the Avamar system on a regular basis it is useful to create a 'blank' checkpoint. This will allow you to go back to an empty starting point each time you roll back to it.

This is Avamar 5.0 and there is no avw_install, but avqinstall. Tried doing that and running avqinstall, but no luck. I am ready to do kickstarting - whatever that means. How do you do that?

This is what I am getting:

[avqinstall v5.0.0-38]

This is where gsan startup fails:

2011/02/25-19:16:53 - - - - - - - - - - - - BEGIN

Identity added: /home/admin/.ssh/dpnid (/home/admin/.ssh/dpnid)

Using /usr/local/avamar/var/probe.xml

xxx-avamar => xxxxx

Checking 0.0 for running gsan processes

Thanks. Now after I re-run avqinstall --noconnectemc --nounpack --norequire_clean_system I get hardware error. Checking for prime completion. Please wait. 2011/02/25-20:51:55.64124 {0.0} [log-messages:107]  ERROR: <0001> HARDWARE: Feb 24 17:56:17 localhost Server Administrator: Storage Service EventID: 2248  The controller battery is executing a Learn cycle.:  Battery 0 Controller 0 Looks like this might have been a problem from very start.
