RAID1 resync very VERY slow using mdadm
I am running Kernel 2.6.18-128.el5 on a 64bit quad core machine with 8GB RAM. Using "mdadm" I setup a RAID1 array between two Western Digital 1.5TB drives. The problem is that the resync is running VERY slow. Here is a current status.
[root@royalflush shared]# cat /proc/mdstat Personalities : [raid1]
