Hi folks I have a raid0 on top of 2 sata disk sda and sdb. after i hot unplug sda, the raid0 still shows online and active. run dd to write to it will fail and dmesg shows scsi io error. but /proc/mdstat shows everything is ok. checked 2.4.27 and 2.6.11.2, both show same problem. mdadm is 1.8 any hint?
