This article mainly explains the "installation of CentOS6.x error" Disk sda contains BIOS RAID metadata "how to solve", the article explains the content is simple and clear, easy to learn and understand, the following please follow the editor's train of thought slowly in depth, together to study and learn "installation CentOS6.x error" Disk sda contains BIOS RAID metadata "how to solve" it!

The error report is as follows: disk sda contains bios raid metadata, but is not part of any recognized bios raid sets. Ignoring disk sda

This situation is similar in ubuntu,suse, but the hints are not quite the same.

Sometimes it's sda, sometimes it's sdb.

It feels like this hard drive has done raid before, but now I don't recognize it. What to do.

When entering the installation selection menu

Press the tab key to enter the command line mode of linux, then add nodmraid after the startup command line (note that a space is added first) and press enter.

After entering the installation process, you will find that the hard drive is found.

The nodmraid command is to turn off the array

It is possible to install the system in this way, but this is required every time the system is reinstalled. How to solve the problem completely.

I tried to be in first aid mode.

Dmraid-r-e / dev/sdb

But report the error.

It seems that we can only put the hard drive on another machine to see what's going on.

Start to deal with this problem right away at work. Put the hard drive on another machine

# dmraid-re / dev/sdb

No raid disks and with names: "/ dev/sdb"

No. Search on the Internet, some friends give an easier way, use parted

# parted / dev/sdb-- script mklabel gpt

# parted / dev/sdb-- script-- mkpart primary 0-1

Warning: the resulting partition is not properly aligned for best performance.

# parted / dev/sdb-- script print

Model: ata toshiba mk1002ts (scsi)

Disk / dev/sdb: 1000gb

Sector size (logical/physical): 512b/512b

Partition table: gpt

Numberstart end size file system name flags

1 17.4kb 1000gb 1000gb primary finished processing, put back to the original machine, unexpectedly no problem, successfully installed the system.

If so, it should be no problem to run parted in emergency mode.

If not, the last resort is dd.

Ddif=/dev/null of=/dev/sda bs=512 count=1
