It is a 7 drive array. If you use 6 of 7 drives, md will not try to re-sync. But I have no idea if how to re-use the previous RAID data.

Hi, everyone. I have a 7 drive dpt_i2o RAID 5 with which a drive going bad coincided with the card going bad. The card (Adaptec mumblefrotz) is going elsewhere, while the drives are now on an aic7xxx SCSI chain set as JBOD. If it were possible to configure an md device to have the same arrangement as the hardware, so I could mount this degraded RAID as read only and rescue some data, it would make me a very happy man. I would just like to make absolutely sure that just loading the drives into an mdadm incantation won't cause any write operations to happen. Is there a way to tell the driver precisely which drive to treat as bad, and not to engage in any write operations what-so-ever ? I'd be most gratefull for any help you might care to give. --Omri Schwarz - 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 - 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
