You got this on Intel (i386) with the final release of the installer code?? That is pretty weird. We are having no problems here in the test lab setting up RAID partitions during the install and then installing to them. Send me more details about this failure. *** Bug 5786 has been marked as a duplicate of this bug. *** We have a Red Hat 6.0 system (installed with a customized red hat 6.0 installer) which has been installed on Linux RAID1 partitions. The box has the following partitions: /dev/md0: root filesystem consisting of sda1 and sdb1 /dev/md1: swap partition consisting of sda2 and sdb2 Raid version is Linux 2.2.10+RAID 19990724. RAID partitions have persistent superblock (autodetectable, 0xfd). We boot the system up always from a diskette (diskette has 2.2.10+RAID19990724-kernel with rdev /dev/md0). Now we are about to upgrade this test system to Red Hat 6.1. This message is to report you about some problems which we ran to when trying to upgrade the system described above: Problem #1: BOOT kernel (on the installation diskette) does not have RAID autodetection enabled. I think it makes sense to enable autodetection. I am not sure that it helps - I am not sure if Linux kernel runs autodetection again after the red hat installer has loaded appropriate SCSI modules. Well, I could work around this problem by putting my own custom kernel to the boot diskette. The custom kernel has autodetection, raid1 and scsi driver (to make things sure) all statically linked in. Problem #2: Red Hat installer does not find existing installation on md0. It seems that it only tries to find the existing installation from sda, sdb, ... devices. So, by fixing the problem number #2 you could make upgrading a raid system relatively easy! (at maximum, user would have to supply a custom kernel to boot diskette) And fixing problem #1 (if it gets fixed only by enabling one autodetect-option) would not increase kernel size dramatically so it would still fit on the boot diskette ;) The 6.1 installer is not able to upgrade existing RAID partitions, and therefore the errors that you are getting. The next release will have the functionality to upgrade in place RAID partitions. |
