+++ This bug was initially created as a clone of Bug #574587 +++ Update: trying this with a raid1 array already created by the BIOS avoided the traceback (at least initially, I made it traceback later). However, it told me that disks sda and sdb had BIOS raid data, but are not part of any recognized BIOS raid sets. Ignoring disks sda, sdb. I'm attaching more support files from this boot with the machine in raid1 mode. --- Additional comment from hdegoede on 2010-03-18 04:17:54 EDT --- Hi Doug, Thanks for the bug report, and thanks for testing! Please file a separate bug for the RAID 1 issue. ------------------------------------------------------------------------------ New bug for raid1 issue.

Hi, I cannot reproduce this, there is one known bug when a false positive of this warning gets shown. When using ISW RAID and *not* selecting the raidset in the advanced storage disk selection screen (you can find the set under the Firmware RAID tab). Is that what you are seeing? IOW are you not selecting the set as part of the drives to have available during the installation ? Regards, Hans p.s. If you look in the dmesg and syslog log files, you will see a lockdep warning there related to mdraid this appears to be very real my ISW raid5 test install hung halfway, with stuck process messages for the kflush threads.
No, on my box I am never presented with the option to select the two raid1 disks as install targets. The two raid1 disks are sda and sdb, and when I select simple disk setup, it eventually shows me sdc and sdd, and I select those and then next and that's when it tells me that sda and sdb are part of a BIOS raid set but don't have raid info and therefore can't be used.

Ah, So you are in effect indeed not selecting the RAID set, and thus hitting the false positive warning bug as I described. For BIOS RAID you need to select advanced storage, not simple. Then on the advanced storage screen switch the Firmware RAID tab, select your set and everything should work from there on. Regards, Hans
Doug, Are you still seeing this when following the instructions from comment 9 ? Thanks, Hans
OK, selecting advanced did the trick. So, no, I don't still see this.
