I have a 8 discs in a DELL T610. We are running a RAID 10 with 2 logical drives with the usual Dell system partitions on the primary C drive. We had 1 drive start predicting failure and then another right next to it. Contacted Dell and they say we have a "punctured stripe". Upon further research, it seems Dell's rebranded LSI card is detecting bad sectors on 1 drive and marking them bad on another. In any case, we need to replace both drives.
So, I am thinking of doing the following:
1. using PING or Gparted to copy the entire array to an external USB hard drive
2. Delete array
3. Recreate array
4. Restore array image from external hard drive
5. Drink celebratory beer.
Is this the best way to go? Any advice or comment would be appreciated.
If you are experiencing trouble because your bad sectors are being written on to good drives, I would not recommend copying them onto any more drives. If you are not concerned with data loss, then by all means, delete the array and remove the faulty drive.
