Hello, for one of our raid1 devices 'mdadm -D' reports 3 devices and 1 failed device, though I'm pretty sure that I specified '--raid-devices=2' when I created that raid-array. One another system, 'mdadm -D' reports the correct numbers. The data from /proc/mdstat report the correct numbers. Any ideas whats the reason for this? Is it a bug in mdadm or has the superblock really wrong data? debye:~# ./mdadm -D /dev/md0 /dev/md0: Version : 00.90.00 Creation Time : Sun May 16 15:22:03 2004 Raid Level : raid1 Array Size : 2441728 (2.33 GiB 2.50 GB) Device Size : 2441728 (2.33 GiB 2.50 GB) Raid Devices : 2 Total Devices : 3 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Mon May 24 20:41:17 2004 State : dirty, no-errors Active Devices : 2 Working Devices : 2 Failed Devices : 1 Spare Devices : 0 Number Major Minor RaidDevice State 0 22 1 0 active sync /dev/hdc1 1 3 1 1 active sync /dev/hda1 UUID : fb539f04:91afe349:3591ed8e:f46b8ef1 Events : 0.26 Thanks, Bernd - 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
