Advanced format drive - replacing a failed RAID member
I have an 8 disk array of Seagate 1.5TB 5900 "green" drives.
I had one go bad and Seagate replaced it under warranty.
The drive I got as a replacement was an "Advanced Format" drive.
Code:
Old drive:
Model Family: Seagate Barracuda LP
Serial Number: 9XW05B85
5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 0
197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 0
New drive:
Model Family: Seagate Barracuda Green (Adv. Format)
Serial Number: 6YD05MN6
5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 0
197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 0
The block counts were slightly different on the drives - the new one was slightly larger.
I used sfdisk to duplicate the partitons from another drive and added it to the array.
It's just a few minutes away from rebuilding.
How much if any problems will this different format drive cause me?
Re: Advanced format drive - replacing a failed RAID member
Since you used sfdisk and copied the partition table over from the previous setup, this will work great :) This is exactly the reason I recommend to use partitions vs. the whole disk for mdadm (it's also nice to be able to properly align the partition).
