Hello, when my system is booting I get the follwing message: md: Autodetecting RAID arrays. md: autorun ... md: considering hdc3 ... md: adding hdc3 ... md: hdc2 has different UUID to hdc3 md: hdc1 has different UUID to hdc3 md: adding hda3 ... md: hda2 has different UUID to hdc3 md: hda1 has different UUID to hdc3 md: created md2 md: bind<hda3> md: bind<hdc3> md: running: <hdc3><hda3> md: personality 3 is not loaded! md :do_md_run() returned -22 I have installled a RAID1 and it is working (that's what I belive). I have checked the archive for this problem but found not very helpfull information. if I do a [root@muckla root]# modprobe -c | grep md-persona alias md-personality-7 multipath alias md-personality-3 raid1 alias md-personality-8 raid6 alias md-personality-2 raid0 alias md-personality-1 linear alias md-personality-4 raid5 [root@muckla root]# [root@muckla root]# lsmod | grep raid1 raid1 14976 3 The module is loaded. What does the message mean ? BTW: Under FC1 I got a similar message - now I have moved to FC2 and got the message I show to you. Reinhard
