What does ls -l /dev/hd[eg]5 show? How about cat /proc/partitions dd if=/dev/hde5 of=/dev/null bs=1024kThanks a lot, Neil, turns out those nodes were not present. After I mknod'd them, all's fine in RAIDland... Quick question: does using extended partitions for RAID affect performance?
The fact that the partitions are "extended" is invisible to most of the kernel, and it could not have any affect of performance.

I remembered that there was a discussion on the list about some abnormal performance penalty if u use a partition instead of a whole disk for MD. But I could not find this discussion via archival or google. Could somebody be kindly enough to point me to the right spot? Thanks a lot.
