Following up on this information I did more testing. I verified that creating a 2-disk raid-5 and extending it to 3 disks always works. 3-disk to 4-disk end up corrupted. BTW I had to change the check in raidreconf for a minimum of raid5 disks from 3 to 2. It worked just fine. I then moved the first two disks to the motherboard (sd[cd] left on the TX4). The situation remained the same (but I did get better performance). I am now less inclined to blame the TX4 and lean more towards raidreconf. I need to create a final test where I hit the disks concurrently without raidreconf to see how they fair... I did some tests and so far failed to provoke any i/o error. -- 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
