Red Hat Bugzilla – Bug 501814
Anaconda installer does not recognize Intel SSD drive
Last modified: 2009-08-10 05:26:31 EDT
Description of problem:
Boot to Fedora 11 preview with an Intel SSD drive as the primary disk. Even thought the driver is enumerated as /dev/sda and can be manually partitioned, Anaconda does not see this as an available device for installation.
This was not a problem on F10.
Version-Release number of selected component (if applicable):
How reproducible: 100%
Steps to Reproduce:
Please attach /tmp/storage.log and /tmp/anaconda.log to this bug report. Thanks.

What do you mean by "does not see this as an available device for installation"? Can you describe the error message or failure case you're getting?
During the "partition wizard, device sda is nowhere to be found. I can see my two other physical devices (SATA harddrives sdb and sdc) and I can also see md0 (which is comprised of sdb1 and sdc1). The physical device sda is not present anywhere in the GUI. If I switch over to a tty, I can access the drive with fdisk and other tools without problem. If there is a way to send a screenshot I will be glad to do that.
My guess is that because your sda device is detected as a dmraid member (according to storage.log - grep for "sda") and we are therefore throwing it out. Do you know if this device used to be a part of a dmraid setup? If so, you may need to wipe the metadata from it, or make sure dmraid is disabled in your BIOS. Hans would probably know better.
The drive should not have any metadata on it since I dd over the first several GB of the drive. Also, my BIOS is set to AHCI and not fake-raid.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
More information and reason for this action is here:
There has been a behavioural change between F-10 and F-11 where in F-10 drives
which contain invalid / stale dmraid (BIOS RAID) metadata / which were part of an incomplete BIOS RAID set would be just seen as the raw disks, where as F-11 these
drives are ignored.
In F-10 in cases where dmraid was detected unwantedly (in case of a complete set, but being disabled in the BIOS for example), the BIOS RAID detection could be avoided with nodmraid. In F-11 this option currently does not work, this is bug
499733. Once 499733 is fixed you can workaround your issue using the nodmraid
installer cmdline option.
Note that a better solution would be to remove the unwanted BIOS RAID metadata from the disks, this can be done using "dmraid -x", be sure to make backups before doing this! "dmraid -x" should leave your data intact, but better safe then sorry.
Also only do this if you really want your disks to not be part of a BIOS RAID set, if for example windows is currently using the disks as a BIOS RAID set you do not want to do this!
