While attempting to use an old 40GB HDD to setup a kind of junky though usable Athon 1GHz system I ran into the following error during the HDD identification/partitioning phase of the installation:Warning: Disk sda contains BIOS RAID metadata, but is not part of any recognized BIOS RAID sets. Ignoring disk sdaHow can I work around this issue?
Strange error message during CentOS 6.5 installation regarding disk containing BIOS RAID metadata?
centos;system installation;raid
I found the solution to this issue in the following thread titled: [SOLVED] CentOS 6 on GA-990FXA-UD5.The solution involved removing the BIOS RAID metadata that apparently was part of a residual software RAID that the 40GB HDD must of been used in. Running this command in the CentOS 6.5 LiveCD in a terminal fixed it:$ dmraid -r -E /dev/sdaDo you really want to erase pdc ondisk metadata on /dev/sda ? [y/n] :To which I replied y.AnacondaThis failure is a little unnerving since it occurs while running the Anaconda installer tool that's typically used by all the Redhat products (CentOS/Fedora/RHEL) and the failure is not graceful. I'm not sure why, but Anaconda cannot deal with this situation itself, and it leaves you in a state where you can see the verbose debug output, which was far from helpful.I saw no other way around the issue from within Anaconda.
