I have a Jmicron Controller on my Board and try to setup a Gentoo System on the Raid 0.
Board: Gigabyte GA-P35-DS3
OS: Live DVD of Fedora release 7.91 (Rawhide)
Dmraid:
dmraid version: 1.0.0.rc14 (2006.11.08) debug
dmraid library version: 1.0.0.rc14 (2006.11.08)
device-mapper version: 4.11.0
lspci:
03:00.0 SATA controller: JMicron Technologies, Inc. JMicron 20360/20363 AHCI Controller (rev 02)
03:00.1 IDE interface: JMicron Technologies, Inc. JMicron 20360/20363 AHCI Controller (rev 02)
dmraid -tay shows this
jmicron_GRAID : 0 625082368 striped 2 256 /dev/sda 0 /dev/sdb 0
jmicron_GRAID 1: 0 61440000 linear /dev/mapper/jmicron_GRAID 206848
jmicron_GRAID 2: 0 501993472 linear /dev/mapper/jmicron_GRAID 61646848
jmicron_GRAID 3: 0 206785 linear /dev/mapper/jmicron_GRAID 63
jmicron_GRAID 5: 0 3951927 linear /dev/mapper/jmicron_GRAID 563640383
jmicron_GRAID 6: 0 57480712 linear /dev/mapper/jmicron_GRAID 567592373
thats ok and correct, also
cfdisk /dev/dm-1
shows me the correct partitions
ls -lart /dev/mapper/
total 0
crw-rw---- 1 root root 10, 63 2007-10-03 16:28 control
brw-rw---- 1 root disk 253, 0 2007-10-03 16:28 live-rw
brw------- 1 root root 253, 1 2007-10-03 20:49 jmicron_GRAID
drwxr-xr-x 2 root root 100 2007-10-03 20:57 .
drwxr-xr-x 13 root root 8580 2007-10-03 20:58 ..
But the jmicron_GRAID has a lot of spaces at the end of the filename.
If I try a
dmraid -ay
dmesg shows me this:
device-mapper: table: 253:2: linear: dm-linear: Device lookup failed
device-mapper: ioctl: error adding target to table
device-mapper: table: 253:2: linear: dm-linear: Device lookup failed

Maybe somebody can help me.
