Everything looks as it should.

Pull One Drive from the mirror and you get:
Giving up waiting for root device. Common Problems:
 - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
   - Check root= (did the system wait for the right device?)
 - Missing modules (cat /proc/modules; ls /dev)

ALERT! /dev/mapper/isw.hgbhachhf_Mirror1 does not exist.

Dropping to shell!

Hi,

Unfortunately dmraid 1.0.0.rc14 doesn't support intel degraded raid disk, you should try rc15 version on jaunty.

Cheers,

Giuseppe.

[Dan Eicher (dhe)]

Will rc15 work on 8.10?

The reason I ask, is I want to run an oracle DB server on this box.
Oracle is very pick as to all the bits and pieces it needs to install.
I've found docs for installing Oracle 11g on Ubuntu 8.10 - but
jaunty is a little close to the bleeding edge.

Thanks,
Dan

I uploaded rc15 on my PPA, you can get it adding in your sources.list the
following lines:

deb http://ppa.launchpad.net/giuseppe-iuculano/ubuntu intrepid main
deb-src http://ppa.launchpad.net/giuseppe-iuculano/ubuntu intrepid main

Cheers,
Giuseppe.

[Dan Eicher (dhe)]

I think there might be some issue with the upgrade to rc15 on intrepid.

I added the addition sources as indicated.
Then:
apt-get update
apt-get upgrade dmraid -
   One package being held back.
apt-get install dmraid -
   dmraidrc15 seem to install fine.
Reboot.
  No block device found (printed 4 times).
  Messages about searching usb and sda
Then:
  Gave up waiting for root device. Common problems:

Ok, so I suspect something goes wrong with the udev rule...

Please, can you paste me the output of:
udevadm info --query=all --name=sda
udevadm info --query=all --name=sdb
dpkg -l | grep dmraid

Cheers,
Giuseppe.

I need some debug logs.
Extract the attached .tar.gz, and you have a dmraid-debug directory

cd dmraid-debug
cp -a sbin/* /sbin/
cp -a 85-dmraid.rules /etc/udev/rules.d/
cat dmraid.initramfs-hook/dmraid > /usr/share/initramfs-tools/hooks/dmraid
update-initramfs -u

Reboot, and you will get /dev/dmraid.log and /dev/dmraid-activate.log

Cheers,
Giuseppe.

FYI - Despite upgrading to this newer version - when I reboot, the machine still shows in the BIOS as RAID group is in a status of rebuild.

[Giuseppe Iuculano (giuseppe-iuculano)]

From ataraid mailing list:

The handling of group RAID sets has changed in rc15 in order to allow
for eg. isw RAID volumes to be selected, hence this is intended.
Wildcard support needs adding in order to allow for easier name
selection.
Patches welcome ;-)

[Giuseppe Iuculano (giuseppe-iuculano)]

Hi,

I've uploaded a snapshot dmraid version on my PPA. Could you try that version please?

For intrepid:
deb http://ppa.launchpad.net/giuseppe-iuculano/ppa/ubuntu intrepid main
deb-src http://ppa.launchpad.net/giuseppe-iuculano/ppa/ubuntu intrepid main

For jaunty:
deb http://ppa.launchpad.net/giuseppe-iuculano/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/giuseppe-iuculano/ppa/ubuntu jaunty main

@Dan: Make sure you have the original /etc/udev/rules.d/85-dmraid.rules before upgrade

Cheers,
Giuseppe.

[Dan Eicher (dhe)]

Hi,
  I'm very sorry, I had to move this machine into production, so I went
with Software Raid 1.

[John Ryan (johnryannz)]

Hi Giuseppe,

I can confirm that your new versions seems to work ok. I had an Intel raid array which the BIOS reported as degraded. In Intrepid 8.10 with rc14 installed, the array made no attempt to repair itself. Installing your version resulted in a clean boot and the array rebuilt itself overnight. The BIOS now report the array as clean.

Thanks!
John

[Giuseppe Iuculano (giuseppe-iuculano)]

Great, committed in the git repository and uploaded to Debian experimental.

[John Ryan (johnryannz)]

Hi Giuseppe,

I might have spoken too soon! I just got home from work, turned on my PC and my array no longer exists. The BIOS reports no RAID volumes defined and both my physical disks are listed as offline members. I have no idea whether this problem was caused by dmraid or not. I will try to restore the array from a live CD and let you know how I get on.

John

[John Ryan (johnryannz)]

Well after a fair bit of mucking around, it looks like I have completely lost my array. The BIOS now reports the array status as "Failed", while /dev/sda is listed as a "Non-RAID Disk" and /dev/sdb is a "Member Disk(0)". However, I cannot seem to be able to add /dev/sda back into the array either in the BIOS or with "dmraid -R isw_bbiechciij_Array /dev/sda". Nor does adding /dev/sda as a hot spare work as it gets added to a new array instead of "isw_bbiechciij_Array" (it will not accept "isw_bbiechciij_Array" as a legal array name to add it to because it is greater than 15 chars long).

The problem all seemed to stem from the fact that when I first re-added a disk to the array last night (prior to the successful rebuild), the name of the array was changed by the BIOS. After a reboot (or in my case, powering off for a day), I then had two different array names and neither could be started. I had to use "dmraid -x isw_daifjieafd_Array" (from either a live CD or the busybox prompt) to delete the new array, then go into the BIOS and re-add the disk again. Unfortunately, this resulted in a new name for the array being generated and so on and so forth. This went on until I deleted the array on /dev/sda instead of the one on /dev/sdb and as a result ended up stuck with the "Failed" array.

whit dmraid rc15 you can try dmraid -R to add a new drive into the array, from
man page:

{-R| --rebuild} RAID-set [device-path]
              Rebuild raid array after a drive has failed and a new drive is
added. For Intel chipset based systems, there are two methods in which a
              new drive is added to the system.

              1. Using OROM to identify a new drive
                  During system reboot, enter OROM and mark the new drive as the
rebuild drive.
                  After booting to the OS, use the dmraid command to rebuild.

                  Example: dmraid -R raid_set

              2. Using dmraid to identify a new drive
                  Boot to the OS and use the dmraid command with the new drive
as the second parameter.

                  Example: dmraid -R raid_set /dev/sdc

              3. Using hot spare drive
                  Mark a drive as hot spare using the "dmraid -f isw -S"
command. Then use the dmraid command to start the rebuild.

Anyway I think this is a different issue, intel rebuild is a new features
introduced in rc15 and it is quite experimental.

Hi Giuseppe,

I concur that this is most likely unrelated. Unfortunately, after much fiddling around I was forced to abandon my array. None of the above commands worked to add a spare or to rebuild. Fortunately, this is only on a test box anyway. When I rebuild it for production use, I will have to carefully weigh my options between dmraid and mdadm.

Thanks for all your work.
John

Regression bug of dmraid :/

I don't know if i must open a new bug:
I've installed today Jaunty alpha4 and work fine with Ext4 partition but have dmraid_rc15.xxx package that don't work with my Intel ICH10 Raid.
I've typed this and others commands without success:
$ sudo dmraid -ay
Intel etcetc was not activated.
ls /dev/mapper list only "control".

After apt-get purge dmraid, apt-get clean and apt-get autoclean I've installed dmraid_1.0.0.rc14-7_amd64.deb (downloaded from http://www.debian.org/distrib/packages) and it works correctly.
Plase fix it soon.
My mainboard is P5Q Deluxe.

[PsYcHoK9 (psychok9)]

Last version, dmraid_1.0.0.rc15-1~exp6_amd64.deb, fix the problem? I don't want break my current installation, and my updates is blocked from the old dmraid_1.0.0.rc14.

Fake upstream fix since Launchpad doesn't support Git yet

[Kyle Jones (mutiny32)]

I would hold off, it looks as if a lot of isw issues are being hammered out still.

[PsYcHoK9 (psychok9)]

The problem still with latest dmraid_1.0.0.rc15-1~exp6_amd64.deb!
I hold my dmraid_1.0.0.rc14! Fortunately was not installed on my main Ubuntu on the raid array (i've tried it on another Ubuntu on single/normal sata disk).

[Kyle Jones (mutiny32)]

Committed fix doesn't fix anything.

This bug was fixed in the package dmraid - 1.0.0.rc15-1~exp6ubuntu1
