HDD Not Visible

Post by alajangi » 2012/02/25 09:43:44

Hi,

In my centos6 server I have 4*2TB hard disks, but I am able to see only 1 disk, may I know the reason why it is not showing the remaining disks in the o/p of

# fdisk -l

Is it configured on raid ? that is why it is showing Disk /dev/sda: 5999.5 GB, 5999532441600 bytes for 8TB ?

I tried to create partition to use the remaining space but I am unable to create as given below, why it is creating the partition from existing cylinders ? please guide me to use my entire harddisk.

fdisk /dev/sda

Yes, that looks like you have a hardware RAID controller that is combining your 4 * 2TB disks into a RAID 5 array of 6TB. Perhaps it would be useful if you hit the FAQ & Readme 1st forum here and grabbed the getinfo.sh script from the first post in there and ran it on your system and posted the output.

Hi,

Thanks for your response,

As it is larger than 2tb it might be unable to create the partition, I was tried to create the partition from parted command, but the following error getting,

# parted /dev/sda
-bash: parted: command not found

Please tell me the problem and please explain me how to confirm the Raid level.

Thanks,
KK.

Try "yum install parted". Assuming you have a true hardware RAID that presents to the OS as a single disk, as Trevor apparently suspects (as do I), then you need to check the RAID utility at boot time, or use the manufacturer's utilities.

If more help is needed then please [url=http://www.centos.org/modules/newbb/viewtopic.php?topic_id=28723&forum=54]provide more information about your system[/url] by running "./getinfo.sh" and showing us the output file.

Hi Phil,

Thanks for your reply, parted is working now, after installed by "yum install parted".

How to extend my /home to max size ? I can extend if there is a partition, but how to create the partition without interrupting the existed data, I am posting the useful output from getinfo, please help me.

We really need to see some of the missing information. Please "yum install pciutils" or perhaps better "yum install pciutils usbutils", run "./getinfo.sh driver" and provide the entire output file pasted in-line including [code] .... [/code] tags. You have a very old kernel installed, but have kernel-headers-2.6.32-220.el6.x86_64. A "yum update" might help get to the current/supported release level.

I've never used a GPT partition table but from the fact that fdisk is listing it, I am guessing that you are not using one since fdisk doesn't understand GPT. In that case the maximum size is 2TB and that is your problem.
