The same thing happens. I try to create a raid1 over nine disks (eight
on Promise SX8):
mdadm -C -l1 -n9 /dev/md0 /dev/sda1 /dev/sx8/0p1 /dev/sx8/1p1 /dev/sx8/2p1 /dev/sx8/3p1 /dev/sx8/4p1 /dev/sx8/5p1 /dev/sx8/6p1 /dev/sx8/7p1
It Segfaults and gives this:
Difference with 2.6.15-mm2 is that 2.6.15 keeps on running.
I'll enable some debug options now. Any advice on what I can try besides
this? Am I doing something wrong?
