Current mdadm raid10 version in CentOS5 is a little old (v2.5.4 - 13 October 2006) and has a bug which sometimes kicks one drive from raid after initial resync and repeats kicking-after-resync when hot added again and again and again.
Do you have some bug numbers ?
The only bugs that exist, are the ones that come with bug numbers, everything else is just user error.
I guess I'm not the only one who is trying to be an a**hole :)
Ask md-raid developer [1] because he states about the bug there (and also somewhere else)
Go find bug number yourself. If you have any counter-information, share it here, correct me and let us all learn.
For all others, %60-70 of raid10 configurations may fail one drive with current raid10 module shipped with CentOS5 because of being somehow old.
Thanks...
