Hi, I have upgrade my system with 3 Raid partitions from Red Hat 9 to Red Hat Enterprise Linux AS, and after upgrading successfully the system say --- Md: autodetecting Raid Arrays autorun ... ... Autorun done Md: autodetecting Raid Arrays autorun ... ... Autorun done Md: autodetecting Raid Arrays autorun ... ... Autorun done Reading block devices EXT2-fs: unable to read superblock Iofs_read_super: bread failled, dev=09:00, iso_blknum=16, block=32 EXT3-fs: unable to read superblock Kernel panic: VFS: Unable to mount root fs on 09:00 I have booted the system with the Install CD en linux rescue mode and I see three raid 1 well syncronized and it seems to be all ok in lilo.conf. Somebody can appoint what can be happening and how to solve this problem?? Thanks in advance.
