Failover with VMWare Server - /var/vm isn't the right size..

VMware use hda5 instade of hda6 for the VM's

Firstly, I'll try to make my question as clearly as possible, despite my poor English and thanks for making the great howto's! After strictly follow this and this howto, saves VMware Server (2.0 Release Candidate 1) the VM's on hda5 as I set hda6. And I see nowhere (with fdisk-l or df -h) /dev/drbd0...

Here what I've done:
Befor the installation of VMware, I have created a new directory as in the aforementioned how to was described by:
Code:
mkdir /var/vm
To save the VM's on that location. During the installation of VMware Server I also changed the Datastore default in /var/vm. (So from here it is obvious that the VM's to be saved on hda5.)
But because DRBD is set at hda6 (see drbd.conf) and I enter
Code:
mount-t ext3 /dev/drbd0 /var/vm
what the location changes from /var/vm on hda5 to /var/vm on hda6, right?

My partition scheme is as follows:
/dev/hda1 | 0.01 GB | boot (primary, ext3, bootable flag: on)
/dev/hda5 | 3.80 GB | / (logical, ext3)
/dev/hda6 | 25.4 GB | unmounted (logical, ext3, will contain the /var/vm directory)
/dev/hda7 | 1.00 GB | swap (logical, swap)

But hda6 should be well formatted with ext3 or just created?

The output from fdisk -l shows:
Code:
Disk /dev/hda: 30.7 GB, 30750031872 bytes
255 heads, 63 sectors/track, 3738 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/hda1              92M   12M   75M  14% /boot
My drbd.conf:
Code:

  incon-degr-cmd "echo '!DRBD! pri on incon-degr' | wall ; sleep 60 ; halt -f";
  startup {

I hope you can help me because I really do not know where I should start right now..

81 views and no answer? Come on I really need your help

falko · Aug 6, 2008

I haven't tried the VMware replication howto, but have you tried to contact the author?

Bart van Kleef · Aug 6, 2008

Thank you for your reply Falko, I'll follow your suggestion right now!

Greetings from The Netherlands!

Hi Bart,

It seems that your DRBD device is not started. Did you start DRBD ? You should not be able to see /dev/hda6. Please let me know at what point of the tutorial you are, as I think you have skipped some steps.

Grtz from Belgica

Bart van Kleef · Aug 11, 2008

Thank you for taking your time thanis, and others who reading this reply right now! I've followed your how to (step for step) again and again with a new installation on both servers. But whatever I do after a reboot of the two servers drbd0 isn't mounted. Not even when I run /etc/init.d/drbd stop/start/restart.
When I try to mount it again (mount -t ext3 /dev/drbd0 /var/vm) I get the following: mount: block device /dev/drbd0 is write-protected, mounting read-only mount: /dev/drbd0 already mounted or /var/vm busy
I have no idea what I'm doing wrong, I hope you do!!

Friendly greetings,

Bart van Kleef

thanis · Aug 12, 2008

Bart, your main issue is the not starting of the DRBD volume. What error do you get when running /etc/init.d/drbd start ? Can you post your drbd.conf for both servers ?

thanks,
Thanis

Bart van Kleef · Aug 12, 2008

Thanis, thanks again!

The rare thing is, I get no error when I run "/etc/init.d/drbd start"

Code:

sproetjuh:~# /etc/init.d/drbd stop

Hi Bart,

I'm guessing you skipped a part of the howto

Please review this:
Code:
Now we define "server1" as the primary/master server:

On "sproetjuh":

drbdsetup /dev/drbd0 primary --do-what-I-say
mkfs.ext3 /dev/drbd0

Wait a while to have the "ext3" filesystem created on /dev/drbd0 and then:

drbdadm connect all
If you don't get errors, you should be able to continue the howto (e.g. mount the /var/vm etc ...). If you do get errors using any of these commands, please post it here !

Grtz,
Thanis

Bart van Kleef · Aug 12, 2008

Thanis,

No that's not the point where I went wrong.

If I can believe google secondary/secondary is normal. Heartbeat makes one primary.

But you're right when I run on sproetjuh:

Code:

drbdsetup /dev/drbd0 primary --do-what-I-say
mkfs.ext3 /dev/drbd0

mount -t ext3 /dev/drbd0 /var/vm

Is drbd0 showed in the output of df -h!

But after a reboot the status of drbd is again secondary/secondary and drbd0 is gone in df -h..

So I guess its hearbeat, here are my configs:

Code:

sproetjuh:~# cat /etc/ha.d/ha.cf
logfile /var/log/ha-log
logfacility     local0
keepalive 1
deadtime 10

node    kimmetjuh
ping [COLOR="Lime"]10.1.1.15[/COLOR]  ## Enter an IP address that is pingable from the ETH0 network !!
respawn hacluster /usr/lib/heartbeat/ipfail

Code:

kimmetjuh:~# cat /etc/ha.d/ha.cf
logfile /var/log/ha-log
logfacility     local0
keepalive 1
deadtime 10

auto_failback off

node    kimmetjuh
ping [COLOR="Lime"]10.1.1.13[/COLOR]  ## Enter an IP address that is pingable from the ETH0 network !!
respawn hacluster /usr/lib/heartbeat/ipfail

Code:

sproetjuh:~# cat /etc/ha.d/authkeys

Code:

kimmetjuh:~# cat /etc/ha.d/authkeys

Code:

Code:

Thanks a lot for all your time! You're my hero

thanis · Aug 12, 2008

Ah, now I see. You used IP address 192.168.1.13 in your haresources, while it is already configured on sproetjhuh. You should use a different free IP address as your virtual IP address for the failover. So you need at least 3 address, 1 for sproetjuh, 1 for kimmetjuh and 1 as the virtual IP. The virtual IP is what you use to connect to the active node.

Grtz,
Thanis

Bart van Kleef · Aug 12, 2008

Ahh, thanks a lot! I changed it in 192.168.1.10 on both nodes. This IP should also be added /etc/hosts because I get still after a reboot secondary/secondary? If yes, something like:
Code:
127.0.0.1       localhost.localdomain   localhost
192.168.1.10    virtual.home            sproetjuh
192.168.1.13    sproetjuh.home          sproetjuh
192.168.1.15    kimmetjuh.home          kimmetjuh
Grtz,

Bart van Kleef

thanis · Aug 12, 2008

No it should not be added to your hosts file, (definitely NOT), but please do the following commands again and post the output here:
1. On kimmetjuh: /etc/init.d/heartbeat stop
2. On sproetjuh: /etc/init.d/heartbeat restart
3. On sproetjuh: tail /var/log/ha-log

I also suggest remove the "vmstart" in your haresources file for testing purposes, as that will probably not work anyway and might actually be the problem

Thanks Thanis

Bart van Kleef · Aug 12, 2008

So here is the output of "tail /var/log/ha-log":

Code:

Thanks,

PS Still I got no eth0:0..

thanis · Aug 12, 2008

Woops, seems I missed something while reading your configs. Your ha.cf is not correct:
Your config:
Code:
kimmetjuh:~# cat /etc/ha.d/ha.cf
logfile /var/log/ha-log
logfacility     local0
keepalive 1
deadtime 10
warntime 10
udpport 694
bcast   eth1
auto_failback off
node    sproetjuh  ## make sure both names are accessible - check /etc/hosts
node    kimmetjuh
ping 10.1.1.13  ## Enter an IP address that is pingable from the ETH0 network !!
respawn hacluster /usr/lib/heartbeat/ipfail
At the ping 10.1.1.13 statement I specifically say that this should be pingable from the ETH0 network, however ... eth0 on both nodes is in the 192.168.1.0 network, so the ping "10.1.1.13" should read 192.168.1.1 (or something else, preferably your internet gateway?). If this is set to a non-pingable host, as it is now, heartbeat thinks the network is down ==> ergo, no services are started because both nodes are down!

Grtz,
Thanis

Bart van Kleef · Aug 12, 2008

This is so stupid! It explains everything.. I let you know if this works!

Thank you so much!

sebastienp · Aug 16, 2008

Hi Bart,

Just a question now that everything looks up and running by your side :

- Does the failover works for you ?

That means, do you get yours VMs running and accessible on the second node when disconnecting the primary node ?

I don't understand why it's not working for me...
So any help/clue/info is appreciated !

Thank you for your feedback,
Regards,
S.

Bart van Kleef · Aug 18, 2008

Sorry for my late reply but I got some other things to do..

Thanis, thanks you so much! Everything works great now!

Sebastien, yes for so far I know. I've seen you're other replies too.
My heartbeat version is 1.2.5 (http://packages.debian.org/etch/heartbeat), DRBD v0.7.21 (http://packages.debian.org/etch/drbd0.7-module-source, http://packages.debian.org/etch/drbd0.7-utils). And VMware server:
VMware Infrastructure Web AccessVersion 2.0.0 Build 101583, VMware Server Version 2.0.0 Build 101586 (http://download3.vmware.com/software/vmserver/VMware-server-2.0.0-101586.i386.tar.gz)
And everything is installed on Debian Etch netinstall (http://cdimage.debian.org/debian-cd/4.0_r4a/i386/iso-cd/debian-40r4a-i386-netinst.iso)

If you got some more questions let me know!

Greets,

Bart van Kleef · Aug 18, 2008

Sorry for my late response!
Thanis the most of you're howto works fine, once again thank you so much!

Sebastien, for so far as I know, only one big problem. When I add vmstart to /etc/ha.d/haresources both nodes are in the secondary state:
Code:
version: 0.7.21 (api:79/proto:74)
SVN Revision: 2326 build by root@sproetjuh, 2008-08-13 11:34:17
 0: cs:Connected st:Secondary/Secondary ld:Consistent
    ns:8 nr:0 dw:8 dr:33 al:0 bm:257 lo:0 pe:0 ua:0 ap:0
When I remove the vmstart line in /etc/ha.d/haresources and reboot the two nodes and login into VMware Infrastructure Web Access all of the virtual machines are "unknown (inaccessible)" and the size of /var/vm is only 4.4GB (hda5). When I create a new virtual machine it shows the correct size of drbd0 (hda6) . Then I remove the unknown machines from the inventory and I add them again to the inventory and everything works fine . All this happening because I think VMware Server 2 starts earlier than DRBD? And if that's true vmstart could not find the machines at /var/vm because it looks on hda5? And that's the reason the both nodes go into secondary/secondary mode? Or my /etc/ha.d/resource.d/vmstart isn't correct:
Code:
#!/bin/bash
case "$1" in
start)
/usr/bin/vmware-cmd -s register "/var/vm/alfresco/alfresco.vmx" 2>/dev/null
/usr/bin/vmware-cmd "/var/vm/alfresco/alfresco.vmx" start 2>/dev/null
;;
stop)
/usr/bin/vmware-cmd "/var/vm/alfresco/alfresco.vmx" stop trysoft 2> /dev/null
;;
status)
if `/usr/bin/vmware-cmd "/var/vm/alfresco/alfresco.vmx" getstate 2>/dev/null | grep -q "getstate() = on"`
then
echo "running"
else
echo "stopped"
fi
;;
*)
echo "Usage: `basename $0` '[COLOR="SeaGreen"]virtual machine file[/COLOR]' {start|stop|status}"
echo "Where "[COLOR="SeaGreen"]virtual machine file[/COLOR]" is like /var/vm/alfresco/alfresco.vmx"
;;
esac
exit 0
For as far as I know, this is just what does not work for me.

Here some information where you asked for in another thread:
Heartbeat v1.2.5
DRBD utils v0.7.2.1
DRBD module source v0.7.2.1
VMware Server v2.0.0 Build 101586 and VMware Infrastructure Web Access v2.0.0 Build 101583

If you have some other questions just let me know!

Creating a snapshot of a virtual machine with Workstation on a Windows host
   vmrun -T ws snapshot "c:\my VMs\myVM.vmx" mySnapshot


Reverting to a snapshot with Workstation on a Windows host
   vmrun -T ws revertToSnapshot "c:\my VMs\myVM.vmx" mySnapshot


Deleting a snapshot with Workstation on a Windows host
   vmrun -T ws deleteSnapshot "c:\my VMs\myVM.vmx" mySnapshot

So it's not surprising that vmstart does't work.
