I tried again with what I thought was the right order but to no affect, so I ran it again without the assume-clean and it rebuilt one of the drives. I assumed that meant mdadm was now okay with the ordering? > usually after doing "mdadm --create --assume-clean" you should check > that data is still readable, if not try changing the order of drives in > "mdadm" and try again. Would it make sense to try and resolve this by constructing a bash script to try all the permitations of drive order until pvdisplay returns something? Thanks for your help and I apologize for essentially asking mdadm questions on the lvm mailling list. _________________________________________________________________ Telly addicts unite! http://www.searchgamesbox.com/tvtown.shtml _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
