Ok, I have tried harder: I have found out how the /dev/mapper directory can be created. I cannot create an ext3 partition with the partition manager. I am verbose as always, hopefully this is ok.
# modprobe dm-mod # ls /dev/mapper control # dmraid -ay # ls /dev/mapper control isw_ddeheebhbf_Volume01 isw_ddeheebhbf_Volume06 isw_ddeheebhbf_Volume0 isw_ddeheebhbf_Volume05 I wondered which device I had to use. Someone suggested to use dmraid -s: # dmraid -s *** Group superset isw_ddeheebhbf --> Active Subset name : isw_ddeheebhbf_Volume0 size : 976783872 stride : 256 type : stripe status : 0 subsets: 0 devs : 2 spares : 0 I have given a stripe size of 128 kB (default for RAID 0). Another suggestion was to use fdisk -l: # fdisk -l /dev/mapper/isw_ddeheebhbf_Volume0 Disk /dev/mapper/isw_ddeheebhbf_Volume0: 500.1 GB, 500113342464 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes d System Device Boot Start End Blocks Id System /dev/mapper/isw_ddeheebhbf_Volume0p1 * 1 19122 153597433+ 7 HPFS/NTFS /dev/mapper/isw_ddeheebhbf_Volume0p2 * 19123 60800 334778535 f W95 Ext'd (LBA) /dev/mapper/isw_ddeheebhbf_Volume0p5 * 19123 21672 20482843+ 7 HPFS/NTFS /dev/mapper/isw_ddeheebhbf_Volume0p6 * 21673 25497 30720000+ 7 HPFS/NTFS I double check that with parted to reduce the risk of data loss: # parted /dev/mapper/isw_ddeheebhbf_Volume0 GNU Parted 1.7.1 Using /dev/mapper/isw_ddeheebhbf_Volume0 ...
