Wait a minute! Stop it, boy! (Sorry; Meat Loaf flashback. :-) You're looking at that partition table with fdisk, *which doesn't understand GPT partition tables*; it's amazing it didn't complain louder. You need to check it with parted, or something else that speaks GPT; the rest your these here is invalid, being based on your assumption that there really is a problem... which there probably isn't. If not with parted, how did you create the GPT partition in the first place?

It does. At least the version i got does: ... WARNING: The size of this disk is 3.0 TB (3000592982016 bytes). DOS partition table format can not be used on drives for volumes larger than (2199023255040 bytes) for 512-byte sectors. Use parted(1) and GUID partition table format (GPT). ... And that's not even the most recent version: fdisk -v fdisk (util-linux 2.20.1) But in the OP-Case the kernel appeared to reported the disc as 2TB, which could be seen in the fdisk output. -- Matthias _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs ^ permalink raw reply [flat|nested] 6+ messages in thread

That's the fdisk which you tell me understands GPT tables *telling you it does not*. > And that's not even the most recent version: > fdisk -v > fdisk (util-linux 2.20.1) > > But in the OP-Case the kernel appeared to reported the disc as 2TB, > which could be seen in the fdisk output. fdisk is not guaranteed to be using a long enough variable there to be able to report the drive size correctly. TTBOMK, *nothing* other than parted presently knows how to create and modify GPT partition tables. Except, apparently, for a program with the *singularly* poorly chosen name of "GPT Fdisk": http://sourceforge.net/projects/gptfdisk/ I know, that sounds like a *really good* name. I've been doing tech support for 30 years; trust me, it's about the worst imaginable name. :-} Cheers, -- jra -- Jay R.

As that does *not* appear to be the thing I linked to, we now have two separate packages from two separate teams, unrelated to one another, which people are going to call "GPT fdisk". Thanks for the pointer, Arkadiusz; my googling didn't turn that up the other night. Cheers, -- jra -- Jay R.
