I have a software raid1 which underwent a recovery recently. While it was recovering, I could not understand why I was seeing an equal amount of *read* I/O as write I/O to the device the raid1 was recovering to. That's to say, the raid1 was rebuilding on to a spare but instead of just writing I was seeing (nearly exactly) the same amount of read I/O as write I/O. The non-spare device was getting almost exclusively read I/O as expected. Why was the spare getting any read I/O at all? -- Jon -- 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
