This worked fine; after fdisk'ing /dev/sdb, deleting the partition and recreating it with the same parameters is showed up as /dev/sdb1, and I was able to add it to the array using mdadm /dev/md0 -a /dev/sdb1. The array is now rebuilding. We still have /dev/sdc1 as a test-case though, so the original problem is still there, just not for two drives but for one. I would really lik= e to figure out why it's happening, so that suddenly it does not happen t= o two drives at the same time, rendering my array dead :/ Tor Arne -- To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
