Without much thinking, I would simply follow the wiki page, mark a device as failed, remove it, repartition it, add it again, and wait for sync to complete. Repeat for all 4 devices and finally --grow with mdadm (followed by xfs resizing) - and of course, all online, while machine is in flight.
That is exactoy what I did with my RAID 10 a bit more than a year ago. It basically worked, but there was one caveat... some part (the ---grow?) which required a certain kernel version for which I had booted a live CD back then...
The thing is, I can't exactly remember what the caveat was. And as I'm about to grow the RAID again (having replaced all hard drives already), I have been looking for the related mails in the archive of this list, but I can't seem to find them...
So I guess we'll have to hope that Neil replies again. Chris -- 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
