Issues related to updating the VMware vCenter Server Appliance

The vCenter Server Appliance update fails to install the update to 5.0 U1 and the log file /opt/vmware/var/log/vami/updatecli.log displays the following error message:
"ERROR: Not enough space on disk to migrate embedded database."
The solution to this problem is this:

• Create a new virtual disk with size 20GB and attach it to the vCenter Server Appliance.
• Log in to the vCenter Server Appliance's console and format the new disk as follows:
• At the command line, type, "echo "- - -" > /sys/class/scsi_host/host0/scan".
• Type, "parted -s /dev/sdc mklabel msdos".
• Type, "parted -s /dev/sdc mkpartfs primary ext2 0 22G".
• Mount the new partition under /storage/db/export:
• Type, "mkdir -p /storage/db/export".
• Type, "mount /dev/sdc1 /storage/db/export".
• Repeat the update process. 

You can remove the new disk after the update process finishes successfully and the vCenter Server Appliance is shut down.
