Since the new parted worked ok (older one didn't), we were happy until we tried a reboot. During the device initialization and after it the system only recognises the 6 or 7 partitions which start before the 2000Gb limit:

Thank you for the suggestion, we'll research it. Haven't tried any other partitioning schemes before :) A couple of short yes-no questions, if I may: 1) Are the GPT tables a feature of Itanium platforms, or can they be used on usual 32-bit (Xeon) servers with Linux inside? 2) Is it possible to convert the partitioning schemes "on-the-fly", or should we backup one array, repartition it and format the new partitions, and restore the data? I believe this is a safer way in any case, but several terabytes are not so easy and quick to back up :) And a longer question: 3) Are there any other features I should know of before relying on GPT? Device naming? Addressing? Driver updates? Boot-up issues? I'll use Google to find more FAQs now... ;) -- Best regards, Jim Klimov mailto:klimov@2ka.mipt.ru
