Single-user does not guarantee any on-disk consistency with what is in memory. If you want to guarantee a consistent image, then you must take it all the way down *and log off* to force the Linux kernel to write everything to disk and have a guaranteed clean disk image. TPC has no way to know what is still pending being flushed, and it cannot create a consistent image without that knowledge. There is no support for notifying the disk controllers from VM or Linux of what is still waiting, and there are no VM or Linux utilities to convey that information. Requirement time, I'd say. It's long past time that IBM supported all the functions for their disks from all the operating systems. -- db ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
