Hi,
I have a problem with dmraid setup on Ubuntu Hardy. I use the Gigabyte SATA2 controller on the Gigabyte P35-DS3P (dmraid detects the raid as jmicron) to setup Raid0 with 2 500GB drives. I also tried the other onboard-controller (ICH9R, "isw" in dmraid), but the result is the same for both.
The installation itself was successful using the FakeRaidHowto (https://help.ubuntu.com/community/FakeRaidHowto) as a guide. I had to use the newer dmraid-packages from ubuntu-proposed (Ubuntu3.1 instead of Ubuntu3), as the older packages would destroy my raid (a bug described somewhere on Launchpad :confused:).
Just for the record: Detection seems to work correctly:
> sudo dmraid -ay
RAID set "jmicron_GRAID" already active
RAID set "jmicron_GRAID1" already active
RAID set "jmicron_GRAID2" already active
RAID set "jmicron_GRAID5" already active
RAID set "jmicron_GRAID6" already active
RAID set "jmicron_GRAID7" already active
> sudo dmraid -r
/dev/sda: jmicron, "jmicron_GRAID", stripe, ok, 976748544 sectors, data@ 0
/dev/sdb: jmicron, "jmicron_GRAID", stripe, ok, 976748544 sectors, data@ 0
Using this setup, I am able to boot both Windows and Ubuntu using Grub. :-)
The problem is, if I do a full reboot (power off completely), the raid is reported as "failed". :-(
Strangely enough, if I boot via the live CD, install the dmraid package and activate the array, everything works again.
I can even reboot again after that. :confused:
