I am running Ubuntu Server 12.04 under vmware.
It's running on a datastore with capacity of 265gb
The VM is on a Thick Provisioned Eager Zeroed disk of 250gb
Leaving 15gb for snapshots etc.
I used default LVM partition setup on installation using all available space creating 'fileserver.vmdk'
i am creating an iSCSI target server LUN
and when attempting to create 200gb file with the following command
dd if=/dev/zero of=/storage/lun1.img bs=1024k count=200000
whilst scanning the datastore for changes I noticed that
a new vmdk file (fileserver-000002.vmdk) is produced until the datastore is filled, I get an out of space error in vSphere client and the vm hangs.
I then need to restore from snapshot or reinstall guest OS.
Forgive my noobiness but I assumed the resulting file would be created within the original virtual disk file fileserver.vmdk.
Why is a second virtual disk created?
Where am I going wrong??
