Hi all.
I have HP microserver n54l with 3x3TB WD CaviarGreen HDD. Could somebody help me with partitioning this HDDs?
I need to know how to make correct create GPT and correct format disks before build RAID5?
So, I did some actions, but I'm not sure, that's correct.
First of all, I deleted all partiotions from HDDs through gdisk utility, and created a new empty GPT. After that I created RAID5 in WebGUI.
Now I checked my disks and see this:
Code
gdisk -l /dev/sdc
GPT fdisk (gdisk) version 0.8.1
Caution! After loading partitions, the CRC doesn't check out!
Warning! Main partition table CRC mismatch! Loaded backup partition table
instead of main partition table!
Warning! One or more CRCs don't match. You should repair the disk!
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: damaged
****************************************************************************
Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk
verification and recovery are STRONGLY recommended.

Is it normal?
