And they work great when used in a RAID-6 array. I've been unable to use either 2.6.14 or 2.6.15 due to bogus scsi errors, not exactly what you see but you might try 2.6.13.4 which works flawlessly for me, LVM using raid6 PV's, some of the raid6 devices use some raid1 components. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
