It does not handle the volumes well, about a week ago, it *corrupted* my array because it couldn't distinguish the superblocks of /dev/sdb and /dev/sdb1. Finally, I used userspace tools (mdadm) to detect my array by specifying the arrays in /etc/mdadm/mdadm.conf
Also, did you specify any of /dev/hd? in /etc/mdadm/mdadm.conf? The new kernel treats IDE devices as SATA devices so you will use /dev/sd? to specify the hard disks. -- Please avoid sending me Word or PowerPoint attachments. See http://www.gnu.org/philosophy/no-word-attachments.html
