DONE!

Gparted + vKVM iso start solved my problem.

Code:
[root@ns2xxx77 ~]# fdisk -l

I think my last chance: (Any prediction for ETA? It has been nearly 45 mins already...)

Actually that is the interesting thing. There is no option like that. Options:
- default partionning
- last partionning choise
- custom partionning (no raid or first disk choice)

Each option shows 40 GB disk space. As always, I am not able to get response to my ticket.

Hello,

I have made my hard raid configuration with MegaCli64:
2 x 40 GB SSD - Raid 0
2 x 3 TB SATA - Raid 0

Code:
root@rescue:~# fdisk -l

Disk /dev/sdb: 5999.9 GB, 5999998009344 bytes
255 heads, 63 sectors/track, 729458 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1      267349  2147480811   83  Linux

Disk /dev/sda: 77.9 GB, 77999374336 bytes
255 heads, 63 sectors/track, 9482 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000bb13a

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      101376+  83  Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2              13        3533    28273664   83  Linux
/dev/sda3            3533        5100    12581888   82  Linux swap / Solaris
root@rescue:~#
As it can be seen there is no problem with that. However, manager shows my disk space as 40 GB. So I have to setup OS on 40 GB space instead of 77~GB

I have tried to install stock CentOS (pxe). It didn't work. I think its because ethernet driver was not recognized.

I have tried to extend my /dev/sda2 partition. However:

Code:
root@rescue:~# e2fsck -fC /dev/sda2
 e2fsck: /lib/libblkid.so.1: no version information
 available (required by e2fsck)
 e2fsck: /lib/libuuid.so.1: no version information
 available (required by e2fsck)
 
 
 
 fsck 1.41.3 (12-Oct-2008)
 fsck.ext3: /lib/libblkid.so.1: no version information
 available (required by fsck.ext3)
 fsck.ext3: /lib/libuuid.so.1: no version information
 available (required by fsck.ext3)
 e2fsck 1.41.9 (22-Aug-2009)
 /: clean, 38370/1769472 files, 309472/7068416 blocks
I have also KVM Over IP. I have tried to install with virtual media (ISO). Server didn't boot from related media. The KVM screen also stucks when I entered the BIOS for boot order.

I have tried all options for three times. Because tech team has not replied my incident ticket for 3 hours.

The question is: Is there any other way to solve this problem? (Another way to extend extf3 or install CentOS on my hard raid 0 SSD with full space)
