New disks for the NAS
I needed some disks for an external backup project - more on that later. Why not replace some of the disks in the NAS with some bigger, and use the old one in the remote place :-)
I got myself two Western Digital WD30EZRX 3TB drives. They were replacing two Western Digital WD10EADS 1 TB drives.
Here is my current layout:
1ada0: WD10EADS
2ada1: WD15EADS
3ada2: WD15EADS
4ada3: TS64
5ada4: WD10EADS
6ada5: WD10EADS
ada0-2 are on the Silicon Image RAID SATA controller, the TS64 on ada3 is on the PATA port on the motherboard, and the last two ada4-5 are on the SATA ports directly on the motherboard. ada4 is my old boot disk before I got the PATA SSD on ada3.
The two zpools (data1 and data2) are lay out as follows:
1[jesper@tranquil ~]$ zpool status
2 pool: data1
3 state: ONLINE
4 scan: resilvered 784G in 11h58m with 0 errors on Thu Feb 28 20:05:15 2013

As you see the RAID-Z (data1) consistes of 4 1TB partitions, and the mirror (data2) of two 0.5 TB partitions.
The big problem is not, that I want to have a RAID-Z with 4 1.5TB partitions, This means that I have to move data around! It becomes kind of a "Towers og Hanoi" problem, as there is almost not enough space.
