AFAIS the end is only aligned to not produce gaps between partitions. > In DASD, the typical REQUIRED grain is 48KiB, so no way we can create a > partition whose size is not divisible by that number.

The optimal grain is 3 MiB since it divides by 1 MiB and 48 KiB. > The point is that I'm not so sure whether aligning the end makes that > much sense from the performance POV if a given partition is at the very > end of the partition table. I don't think it is important for performance. In general I would not align the end of the last partition and thus avoid unused space at the end. I personally do not mind that little wasted space but other people might be picky about it (e.g. if other partitioning tools report a tiny piece of unused space). ciao Arvin -- Arvin Schnell, <[email protected]> Senior Software Engineer, Research & Development SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) Maxfeldstraße 5 90409 Nürnberg Germany -- To unsubscribe, e-mail: [email protected] To contact the owner, e-mail: [email protected]
