We are using VSphere 4.1
Today, we found the backup software cannot be completed.
As usual, we go back to the VM and remove the snapshot generated by the backup software and there is only one snapshot.
Normally, it takes about 2-3 hours as the snapshot size is over 30 GB.
The VM contain the SQL Server which VCenter is using.
Later, we need restart the VM as the VM take 100% CPU Usage.
At that time, the snapshot is still under removing.
After the VM is restarted, we restarted the VCenter Server as well.
Then, we found the remove snapshot task disappear.
When we try to create a new snapshot, it shows "Another Task is already in Progress."
Follow the instruction in "Restarting the management agents on an ESX or ESXi Server", we restart the Management Agents of the related host.
Then, we try to create a new snapshot and shows error "A general system error occurred: Unable to save the snapshot file."
In the Snapshot Manager, it shows "Consolidate help - 1".
Then, we try to remove all snapshot and shows error "The task was cancelled by users".
Now, the VM is stuck at the snapshot stage.
how can we do?
