Re: residual Promise tattooing confuses FC5

    Has anyone else run into this problem. We have a machine which
had hardware Promise RAID in use with RedHat 9. When we installed
Fedora Core 4 on the machine, since dmraid didn't recognize the
Promise hardware RAID partitions, we disabled the Promise hardware
RAID in the BIOS and installed FC4 with software RAID-1 partitions.
The FC4 install CD recognizes these partitions without complaint.
However the FC5 install CD complains that the partition map on the
drives are corrupted. My guess is that dmraid is seeing some residual
tattooing on the drives and not using the software RAID. Is there some
way to disable dmraid on this system during the installation? I would
rather not have to do a low level format just to eliminate the residual tattooing.

We had something related. In our case it was a disk which used to be part of an LVM volume, but which we later separated and put as a stand alone disk. It works fine in normal use but would mess up anaconda when we tried to update it. I did quite a bit of debugging when we moved from FC3 > FC4 but never got round to bugzillaing it. I'm going to do the FC4 > FC5 move on it in the next few days and will write it up properly this time if the problem persists.
