Should I be scared? What does it mean? What should I do about it? I
wouldn't like to loose the data.
If it helps, my setup looks like that:
HDD1-sda2-\
HDD2-sdb2-|__RAID-10--LVM-2
HDD3-sdc2-|
HDD4-sdd2-/
I'm running 2.6.17.8 kernel.
...
So this basically means, that LVM was set up on /dev/sda2 some time ago,
but it was never removed from there - instead, RAID-10 was set up on
that partition?
I don't think so. if sda2 is part of a raid10 md array probably the
beginning sector of the md device maps to the beginning sector of the
real device, hence lvm will find an lvm signature on /dev/sda2.
Should I do something to fix the things? What?
yes, re-enable md_component_detection in lvm.conf, why did you disable
that?
