----> Make a full backup of your system or atleast of database before performing following actions!!! <----
Add new HDD to your server and then login via ssh. Do
mkdir /mnt/secondhdd
Now follow these instructions:
fdisk -l
You should see something like this:
[root@testbilling ~]# fdisk -l
Disk /dev/disk: hdd space GB, 214748364800 bytes
255 heads, 63 sectors/track, 26108 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/xvda1 * 1 13 104391 83 Linux
/dev/xvda2 14 1044 8281507+ 8e Linux LVM
/dev/xvda3 1045 26108 201326580 83 Linux
Disk /dev/xvdd: 71 MB, 71251968 bytes
255 heads, 63 sectors/track, 8 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Now do:
fdisk /dev/disk , change disk to correct value.
Press n, then p, and choose number, usually you'll need to press 3 here. You must chose from 3 to 4 , because 1 and 2 is already used by other partitions. Then you'll be questioned about other thing, just press ENTER and when you'll see Command (m for help): again, enter write and press ENTER. If everything was fine, fdisk will ask you to reboot the system, reboot it and follow next steps.
Now you'll need to make filesystem for new partition. Do:
mkfs.ext3 /dev/diskandnumber (for example mkfs.ext3 /dev/xvda3). It will take couple of minutes , depending of side of new hdd.
Last task is tell Linux to mount this partition at startup.
open /etc/fstab file with your favorited editor like nano or mcedit, you should see something like this:
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 /dev/VolGroup00/LogVol01 swap swap defaults 0 0
add this line to the most bottom of the file:
/dev/disknumber /mnt/secondhdd ext3 defaults 1 1
Example: /dev/xvda3 /mnt/secondhdd ext3 defaults 1 1
The file should look something like this:
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 /dev/VolGroup00/LogVol01 swap swap defaults 0 0 /dev/disknumber /mnt/secondhdd ext3 defaults 1 1
Thats it, now reboot machine and check if new hdd is mounted:
df -h
you should see something like this:
[root@testbilling mor]# df -h
