I am trying to create a 2 vm cluster which will be running SLES10.
I followed the 'cluster in a box' procedure:
1 - Created a New vm, just like if it was a standalone server.
2 - Added a disk on SCSI bus 1:0 (original disk was on 0:0)
3 - This automaticaly added a second SCSI controller on the vm
4 - Set the SCSI bus sharing to Virtual
5 - Created a second vm, same as the first one
6 - Added an existing disk on bus 1:0
7 - Set the new controller to virtual as well
8- I then started the first Vm and... crash with the following message:
VMware ESX Server cannot open the virtual disk, "/vmfs/volumes/....../ClusterNode1/ClusterNode1_1.vmdk" for clustering. Please verify that the virtual disk was created using the 'thick' option.
Cannot open the disk '/vmfs/volumes/..../....vmdk' or one of the snapshot disks it depends on.
Reason: thin/TBZ disks cannot be opened in multiwriter mode..
Do I have to create these 'special' disks using the console with 'vmkfstools'?? with the 'thick' option?
I always though ESX was creating Thick disks by default.
Thank you!
I have the same problem reating 2 VMs for MSCS
I'm looking for a solution too
i'll be back if I have any idea
it seems that there are no way from the GUI.
the only working solution i've found is there : http://communities.vmware.com/thread/58188
summary : create the disk from command line using the option -d thick
When creating the Hard Disk in the UI, select the option under Disk Provisioning that states the drive will be used for clustering.
Hi,
we have setup a "cluster across boxes" and successfully created a shared disk as "Virtual RDM" disk. We used the utility vmkfstools with the option -d eagerzeroedthick from the service console.
According to this description: http://www.vmware.com/pdf/vi3_35/esx_3/r35u2/vi3_35_25_u2_mscs.pdf this procedure has even to be followed for a 'cluster in a box'
Hope this info did help,
Josi.
You need disk in a format for cluster (and FT) that is called "EagerZeroed Thick".
