Hello again, Been an interesting day. I'm attempting to use parted to create a partition on a 28TB volume which consists of 16x2TB drives configuired in a Raid 5 + spare, so total unformatted size is 28TB to the OS.. However upon entering parted, and making a gpt label, print reports back as follows; Model: Areca ARC-1680-VOL#000 (scsi) Disk /dev/sdc: 2199GB Sector Size (logical/physical): 512B/512B Partition Table: gpt Why is the disk reporting ~2TB? Should I be using another partitioning tool for such a large volume? - aurf
What filesystem are you planning to use, I am hoping for XFS in such a large volume.>>> <aurfalien at gmail.com> 1/11/2011 4:41 PM >>>Hello again, Been an interesting day.

The rebuild times are probably going to be days, and the chance of a second spindle failure in that time is high enough to make it dangerous. Use RAID-6 at least. Steve
