Well, this is probably a FAQ, but I've really looked around and can't seem to find how to do it.. So here's the story: I just created a RAID1 array. I did this by simply creating a single disk array, and then copying the data from the original disk onto the array, and then trying to raidhotadd the original disk once the array was created and the contents fully copied. I did NOT use a failed-disk directive for the original disk, as I have had at least one experience where the failed-disk directive was ignored and that drive was mirrored to anyways.. Luckily the failed-disk had no important data on it that time, but I didn't want to risk it this time.. At any rate, now it seems that my hotadded disk is NOT part of the active array, but is in fact a spare. Here's the relevant lines from mdadm --detail /dev/md0 Raid Disks : 1 Total Disks : 2 Preferred Minor : 0 Active Drives : 1 Working Drives : 2 Failed Drives : 0 Spare Drives : 1 It should be a simple matter to convert that spare to an active drive, right? Especially for RAID1. How do I go about doing that? I've found a tool called raidreconf by the author of the RAID HOWTO, but I'm reluctant to just run that and hope for the best, especially since it seems to be written for just RAID0 and 5 (the rather scant manpage makes no mention of RAID1 whatsoever). Does anyone have any experience with using raidreconf for RAID1, or have a way to hotadd a disk and have it become active, instead of being a spare? -- Mike Perry Mad Computer Scientist fscked.org evil labs - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
