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,

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
