Bug#392764: Can't reproduce on PowerStack, MAC partition issue only?

Sorry, but it looks like I don't have the hardware to track this down, yes, it is a mac partition table issue. There where actually two bugs, one which i fixed, and was long fixed in ubuntu but the fix didn't go back to debian until i investigated, and the other which is not in parted, but in partman, and is still open. It is possible to test this on any hardware, but you would need a second disk if your firmware/bios is not able to boot from mac partition tables, like i believe is the case for PReP boxes. This can also be tested on plain x86 boxes with a second disk. My believe is that since mac partitions used to not have the RAID flag, that partman somewhere has some explicit test for x86 partitions, and sets the RAID flag only in those cases, or something. I will try to reproduce his on pegasos and its amiga partition tables, which are in the same case as the mac partitions. partman actually *ERASES* the raid flag set by hand by parted, which is rather strange, and hints strongly at some problem in partman-md (but also possibly mirrored in partman-lvm, which has a similar flag setup).

That corresponds to Sven's findings. Sorry, but it looks like I don't have the hardware to track this down, According to Sven, it should be possible to create a MAC partition table for testing, even if an MSDOS table is normally used. I have no idea if this is true or what risks that may bring. If you want to give this a go, installing in expert mode will allow you to select the type of partition table when you select a disk in partman. HTH anyway, Yes, thanks for taking the trouble to look into this. pgpzYT9emiTk1.pgp Description: PGP signature
