I have 2 Raid5 arrays on a hpt375. Each has a (unused) spare disk. With change from 2.4 to 2.6 I can not put the spare disk to sleep or standby. It wakes up after some seconds. /proc/diskstat shows activities every 2 to 5 seconds. It is a problem of the plain kernel driver ( not application ) because if i raidhotremove the drives it can sleep/standby and no activities are shown in /proc/diskstats. If the whole Array is unmounted, there are no activities an all drives. It seems that access to md always causes an access at the spare disk ?! Any hints ? Anyone with the same problem ?
