Hi together,
i am trying to setup a Vmware Server failover installation (on centOS 5) but
noticed some problems.
My configuration:
Drbd:
---
resource drbd0 {
protocol C;
syncer {
rate 50M;
}
on kempen.v121.dus1.th {
device /dev/drbd0;
disk /dev/sda10;
address 10.10.121.81:8766;
meta-disk internal;
}
on sandiego.v121.fra3.th {
device /dev/drbd0;
disk /dev/sda10;
address 10.10.121.82:8766;
meta-disk internal;
}
}
resource drbd1 {
protocol C;
syncer {
rate 50M;
}
on kempen.v121.dus1.th {
device /dev/drbd1;
disk /dev/sda11;
address 10.10.121.81:8776;
meta-disk internal;
}
on sandiego.v121.fra3.th {
device /dev/drbd1;
disk /dev/sda11;
address 10.10.121.82:8776;
meta-disk internal;
}
}

Heartbeat:
haresources:
---
kempen.v121.dus1.th drbddisk::drbd0 Filesystem::/dev/drbd0::/kempen::ext3
sandiego.v121.fra3.th drbddisk::drbd1 Filesystem::/dev/drbd1::/sandiego::ext3
---
Heartbeat and drbd are working without Problems (both newest stable Version).
Then i installed VMware Server on both Servers (also the newest stabel Version).
On "kempen.v121.dus1.th" the directory where the vmwaredisks are located is
configured to /kempen (drbd0)
On "sandiego.v121.fra3.th" the directory where the vmwaredisks are located is
configured to /sandiego (drbd1)
The other parameters are default (except user and webports)
I installed windows 2000 in a VM located on "kempen.v121.dus1.th" (i called it
vmtest.v121.dus1.th)

This worked fine.
On "sandiego.v121.fra3.th" i configured a second "Datastore" (over the VMWare
Webinterface) which i called "kempen" and which points to /kempen
Then i tried to do a failover.
I stopped heartbeat on "kempen.v121.dus1.th". drbd0 failed to
"sandiego.v121.fra3.th" and is mounted on /kempen

[r...@sandiego /]# df -h

The VM files are now located on "sandiego.v121.fra3.th" instead of
"kempen.v121.fra3.th":

[r...@sandiego /]# ls -al /kempen/vmtest.v121.dus1.th/

Then i tried to register and start the VM:
---
Register:
[r...@sandiego /]# vmrun -T server -h https://localhost/sdk -u root -p test
register "[kempen] vmtest.v121.dus1.th/vmtest.v121.dus1.th.vmx"
[r...@sandiego /]#
Start:
[r...@sandiego /]# vmrun -T server -h https://localhost/sdk -u root -p test123
start "[kempen] vmtest.v121.dus1.th/vmtest.v121.dus1.th.vmx"
In the webinterface of sandiego VMware asks me if i moved or copied the VM.
I answered: moved / copied (both does not work - why he asks me this?)
On the shell i see:
Error: Unknown error
---
When in now have a look into "/var/log/vmware/hostd.log"
I get this error:
---
center: Cannot open the disk
'/kempen/vmtest.v121.dus1.th/vmtest.v121.dus1.th.vmdk' or one of the snapshot
disks it depends on.
Reason: Failed to lock the file.
---
I then noticed that i have to delete the *.lck files
Is there a better way to do the failover or should i just delete all *.lck
files after failover and before start?
And is there a way to prevend this "did you move oder copy this vm" questions?
Thanks in Advanced!
Mit freundlichen Grüßen / best regards
Sebastian
