Hide Forgot
i have a RHEL 5.5 installation. during the setup i have created a software-raid 1 setup for /boot and /. i tried to upgrade to RHEL 6, but it does not detect my installation ("The root for the previously installed system was not found"). also, the v6 rescue system is not able to automatically mount my partitions which works fine with 5.5. rescue system.
Created attachment 480904 [details] syslog
Created attachment 480905 [details] storage.log
i found out that in the storage log it says 01:49:32,587 WARNING : mount of mpatha as ext3 failed: mount failed: (9, None) maybe this helps.
anaconda.log says: 01:49:32,565 INFO : failed to set SELinux context for /mnt/sysimage: [Errno 95] Die Operation wird nicht unterstützt 01:49:32,566 DEBUG : isys.py:mount()- going to mount /dev/mapper/mpatha on /mnt/sysimage as ext3 with options ro
Please see the installation guide. Specifically section 37.1: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html-single/Installation_Guide/index.html#ch-upgrade-x86 "Red Hat does not support upgrades from earlier major versions Although anaconda provides an option for upgrading from earlier major versions of Red Hat Enterprise Linux to Red Hat Enterprise Linux 6, Red Hat does not currently support this. More generally, Red Hat does not support in-place upgrades between any major versions of Red Hat Enterprise Linux. (A major version is denoted by a whole number version change. For example, Red Hat Enteprise Linux 4 and Red Hat Enterprise Linux 5 are both major versions of Red Hat Enterprise Linux.) In-place upgrades across major releases do not preserve all system settings, services or custom configurations. Consequently, Red Hat strongly recommends fresh installations when upgrading from one major version to another."
