Hello, World, I'd asked this on dW last week but got no reactions: I am unsure on the viability of this approach: In a given file system, there are two internal storage pools and one external (GHI/HPSS). Certain files are created in one internal pool and are to be migrated to the other internal pool about one day after file closure. In addition, all files are to be (pre-)migrated to the external pool within one hour after closure. Hence: typically, blocks of a file being already pre-migrated to external (but not purged on the initial internal pool) are to be moved from one internal pool to the other. A slight indication that there might be some issue with such an approach I've found in a dW post some years back: https://www.ibm.com/developerworks/community/forums/html/topic?id=77777777-0000-0000-0000-000014797943&ps=25
However, time has passed and this might work now or might not. Is there some knowledge about that in the community? If it would not be a reasonable way, we would do the internal migration before the external one, but that imposes a timely dependance we'd not have otherwise.
