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 -s -s isw_jffegbfhc_data > *** Group superset isw_jffegbfhc > --> Active Superset > name : isw_jffegbfhc_data > size : 3131113472 > stride : 128 > type : raid01 > status : ok > subsets: 2 > devs : 4 > spares : 0 > --> Active Subset > name : isw_jffegbfhc_data-0 > size : 1565556736 > stride : 128 > type : mirror > status : ok > subsets: 0 > devs : 2 > spares : 0 > --> Active Subset > name : isw_jffegbfhc_data-1 > size : 1565556736 > stride : 128 > type : mirror > status : ok > subsets: 0 > devs : 2 > spares : 0 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?
