A method to prevent the inadvertent removal of volumes on a storage system is disclosed. In one embodiment, such a method includes receiving a request to remove (e.g., delete, detach, unmask, etc.) a volume on a storage system. In response to receiving the request, the method initiates at least one process to monitor the volume for I/O activity over a specified period of time. In the event the at least one process does not detect I/O activity to the volume during the specified period of time, the method executes the request by removing the volume. In the event the at least one process detects I/O activity to the volume during the specified period of time, the method denies the request to remove the volume. A corresponding system and computer program product are also disclosed.

Accidental-volume-removal prevention

An indication of a problem within the computing environment can be received by a data processing system external to a computing environment. Based on the indication of the problem within the computing environment, the data processing system can select a data log filter. The data log filter can be configured to access, from each of a plurality of data logs, a respective data set comprising log entries that are candidate indicators of the problem. Each of the plurality of data logs can be generated by a respective electronic device that is a member of the computing environment. The data processing system can access the respective data sets from the plurality of data logs using the data log filter, and output each respective data set.

Guided troubleshooting with autofilters

A method for live-migration of an operating system and an application is provided. The operating system runs on a first computer. The application may run on the operating system. The live-migration may be performed to a second computer while the application showing no externally detectable downtime during live-migration of the application. The method may comprise operating a tracking tool that may track and store data modifications to a disk-system of the computer in a tracking file, triggering a shutdown of the first computer while the tracking tool continues to operate in tracking mode and shut down the first computer completely. Then restarting the first computer and sending the data modifications stored prior to the complete shutdown of the first computer to the second computer, which then may be started based on the sent data, followed by starting the application such that from an external perspective no application disruption is detectable.
