We have a server with about 6x750Gb SATA drives setup on a hardware RAID controller. We created hardware RAID 5 on these 6x750GB HDDs. The effective size after RAID 5 implementation is 3.4TB. This server we want to use it as a data backup server. Here is the problem we are stuck with, when we use fdisk -l, we can see the drive specs and its size as 3.4TB. But when we want to create two different partitions of 1.7TB each, then we get the error "out of range" while specifying cylinders. And if we go for one single partition of 3.4TB, mke2fs returns error when we format the partition for ext3 file system and after some specific duration it exits with a error "Inodes not found... " similar errors. Any help / suggesstions / ideas to get around this problem are highly appreciated. -------------- next part -------------- An HTML attachment was scrubbed...

If you really want to use partitions, use parted and create a gpt disklabel (the standard msdos won't work either). Note that you won't be able to boot from this disk. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
