- - Failover with VMWare Server - /var/vm isn't the right size.. (http://www.howtoforge.com/forums/showthread.php?t=25763)

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... :confused:

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

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

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

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

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 :)
Groeten uit Antwerpen.

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

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

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 start

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

Code:

Cordial greetings and thanks for your help,

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

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

warntime 10

udpport 694

bcast   eth1

auto_failback off

node    sproetjuh  ## make sure both names are accessible - check /etc/hosts

node    kimmetjuh

ping 10.1.1.15  ## 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

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

Code:

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

auth 3

3 md5 failover  ## this is just a string, enter what you want ! auth 3 md5 uses md5 encryption

Code:

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

auth 3

3 md5 failover  ## this is just a string, enter what you want ! auth 3 md5 uses md5 encryption

Code:

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

sproetjuh 192.168.1.13 drbddisk::vm1 Filesystem::/dev/drbd0::/var/vm::ext3 vmstart

Code:
