Package: dmraid
Version: 1.0.0.rc16-4.2
Severity: important

Hello,

Today I replaced a set of aging 1TB drives which were in an ISW raid01
set with new 3TB disks. After creating a new set (in the bios) I was
dismayed to find the new mapper blockdev *smaller* than before.

I tried again using the dmraid utility, rather than setting it up in the
bios, so I had something more concrete to report.

Each disks is indeed 3TB (phew)
> # blockdev --getsize64 /dev/sd{c..f}
> 3000592982016
> 3000592982016
> 3000592982016
> 3000592982016

Creating the array:
> # dmraid -f isw --create data --type 01 --disk 
> /dev/sdc,/dev/sdd,/dev/sde,/dev/sdf
> 
> 
>      Create a RAID set with ISW metadata format
> 
> RAID name:      data
> RAID type:      RAID01 (isw RAID10)
> RAID size:      5589G (11721047228 blocks)
> DISKS:     /dev/sdc, /dev/sdd, /dev/sde, /dev/sdf,
> 
> 
> About to create a RAID set with the above settings. Continue ? [y/n] :y

Listing details of the new array. I note that each of the subnet mirrors
has a size of 1565556736 blocks (~746GB) and the superset seems to be
correctly striping these to 3131113472 blocks (~1493GB).

dmraid -b reports the appropriate number of blocks available per device:
> # dmraid -b | grep WD
> /dev/sde:   5860533168 total, "WD-WCC1T1097209"
> /dev/sdf:   5860533168 total, "WD-WCC1T1476226"
> /dev/sdc:   5860533168 total, "WD-WCC1T1503861"
> /dev/sdd:   5860533168 total, "WD-WCC1T1080929"

For context, this system has one other raid array. The root volume is a
pair of raid1 SSDs:

> # dmraid -s isw_deagibdgda_root
> *** Group superset isw_deagibdgda
> --> Active Subset
> name   : isw_deagibdgda_root
> size   : 125040896
> stride : 128
> type   : mirror
> status : ok
> subsets: 0
> devs   : 2
> spares : 0

This size is correct - each SSD is 125045424 blocks long.

Is this related to the lack of GPT support in dmraid?

Thanks,
Nick
