strange raid 1 drive problem please help
| Posted by need4bw, 03-15-2012, 12:48 PM |
| My server came with software raid 1 it has 2x2tb drives
I want to get rid of all raid. So i was told to reinstall centos 5 64 bit with cpanel
Before i reinstalled i was told to select install without raid and that i would have to format and install the 2nd drive through whm after.
However every time i try this, the second drive when i mount it is only showing 21 gigs of free space??
What is happening with this. Is it no formatting and still has the old partitions on it?
Home2 is showing only 21 gigs of space? it should be showing 1.8tb or more??
I am confused over this how do i just get the server to enable home2 to have 1.8tb of space?
i am seeing this in fdisk -l

seeing some auto raid detection on sdb??
in df -f

/dev/root 20G 3.6G 15G 20% /var/named/chroot/var/run/dbus
/dev/sdb1 20G 173M 19G 1% /home2
what is happening? and how to get that auto raid detection off?
can i expand home2 to 1.8tb to match drive one with ssh?
thanks for any guidance.

| You need to remove the raid information from the drive seems.

| No you should not need KVM
make sure all partitions are unmounted
and remove them with the fdisk /dev/sdb command
and reformat
