Issue Description
In the test of the convergence of RH2280 and SSD hard disk, there are 5 disks configured with RAID0 in the RH2280 with capacity of each disk is 500G and a SSD hard disk with capacity of 128G. The OS Linux is installed in the 5 disks of RAID0 and the SSD is used to load the file system format of ext3 to the system. When we do the partition, it occurs some error. The warning:“The system can’t do the partition without GPT partition
Handling Process
When the total capacity is greater than 2T, the usual partition tool doesn’t work anymore. We should use the GPT partition tool. In Linux, we use “parted” and in FreeBSD, we use “GPT”. Here is the operation in Linux.
If the device is /dev/sdb
parted /dev/sdb
parted> mklable gpt
parted> print
parted> mkpart print
Root Cause
The total capacity of 5 SATA disks with 500G each and a SSD disk with 128G is greater than 2T. The partition can’t be done with the Linux partition tool.
