I did a resync since, which ended up with the same mismatch_cnt of 184. I noticed that the count *was* reset to zero when the resync started, but ended up with 184 (same as after the check). I thought that the resync just calculates fresh parity and does not bother checking if it is different. So what does this final count mean? This leads me to ask: why bother doing a check if I will always run a resync after an error - better run a resync in the first place? -- Eyal Lebedinsky (eyal@xxxxxxxxxxxxxx) <http://samba.org/eyal/> attach .zip as .dat - 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
