I tested a RHL6.1 upgrade with the RHL6.1 Boot CD I have /, /home mirrored on 2 disks (Raid1) when I first installed the system from the CD, using the Graphic version of your installer (disk druid) : The problem is : I selected a "Upgrade", but the installer doesn't detect the partitions : scsi controller : aic7xxx May be including the raid1 (and others) module in the upgrade process will fix this. (or include a fdisk whith recocgnize the 0xfd partition flag). Hope this helps Configuration : [root@air denis]# df -k Filesystem 1k-blocks Used Available Use% Mounted on /dev/md1 1035596 478772 504216 49% / /dev/md2 7574072 57668 7131656 1% /home [root@air denis]# more /proc/mdstat Personalities : [raid1] read_ahead 1024 sectors md2 : active raid1 sdb1[1] sda1[0] 7694976 blocks [2/2] [UU] md1 : active raid1 sdb5[1] sda5[0] 1052160 blocks [2/2] [UU] md0 : active raid1 sdb6[1] sda6[0] 136448 blocks [2/2] [UU] /dev/sda ---Starting--- ----Ending---- Start Number of # Flags Head Sect Cyl ID Head Sect Cyl Sector Sectors -- ----- ---- ---- ---- ---- ---- ---- ---- -------- --------- 1 0x80 1 1 0 0xFD 254 63 957 63 15390207 2 0x00 0 1 958 0x05 254 63 1023 15390270 2377620 3 0x00 0 0 0 0x00 0 0 0 0 0 4 0x00 0 0 0 0x00 0 0 0 0 0 5 0x00 1 1 958 0xFD 254 63 1023 63 2104452 6 0x00 254 63 1023 0xFD 254 63 1023 63 273042 /dev/sdb ---Starting--- ----Ending---- Start Number of # Flags Head Sect Cyl ID Head Sect Cyl Sector Sectors -- ----- ---- ---- ---- ---- ---- ---- ---- -------- --------- 1 0x80 1 1 0 0xFD 254 63 957 63 15390207 2 0x00 0 1 958 0x05 254 63 1023 15390270 2377620 3 0x00 0 0 0 0x00 0 0 0 0 0 4 0x00 0 0 0 0x00 0 0 0 0 0 5 0x00 1 1 958 0xFD 254 63 1023 63 2104452 6 0x00 254 63 1023 0xFD 254 63 1023 63 273042
assign to installer
RAID upgrades are not support in release 6.1, so that is why you are seeing problems. Try the latest installer that is available in beta and you should be able to upgrade using that code.
