I am a development manager in an IS shop and am responsible for a SAS application that is running on an HPA UNIX box. We recently did the following and experienced data corruption that caused the application to be down for 1 week. We have yet to get to root cause. I would like to understand if it is a low risk to move data around and add space during working hours or should the server be taken off-line when performing these types of routines?
Work that was done: a physical volume move was done to be able to add storage to the array filesystem. I am told that this needed to be done because of physical limitations within the volume group that contained the array filesystem, and the limitations occured because the array filesystem was never expected to become so large.
Tests were performed on the box w/o errors. Nothing has been found from an application perspective.
