Woh ! Absolutely nobody can help me on this question ? I've already
asked about this on 4-5 lists or forums, and I've cumulated : 0 answer.
Where could I find help on this subject ? The kernel team ? Who has
developped this part (boot on initramfs and device detection) ?
I'm stucked on that problem since 2 weeks. Please, help :)
Known issue... though I can't seem to find the bug # now.
What is a known issue ? Running a degraded raid 5 at boot is not possible ?
Ben Ben a écrit :
So here, I suspected that the wrong option was passed to mdadm in
initramfs, and tell it to not to run a degraded array.
I've found (with grep on initrams content) that the file
/etc/udev/rules.d/85-mdadm.rules contains this line :
SUBSYSTEM==block, ACTION==add|change, ENV{ID_FS_TYPE}==linux_raid*, \
RUN+=watershed /sbin/mdadm --assemble --scan --no-degraded
I guess it's the boot parameter for mdadm ! So, I changed it, made a new
initramfs, reboot with only 2 disks and... nothing more, it doesn't
start anymore :/
Not sure what's going wrong without any description other than it
doesn't start anymore, but that should allow you to boot in a degraded
array.
It does the same thing I describe before : initramfs loads, md driver
try to run array but can't, so it hangs around 3 minutes and give me
the hand in the initramfs console.
Here's outputs of cat /proc/mdstat at this stade. I gave many try
(reboot), as the output is not always the same :
$ cat /proc/mdstat
Personalities : [raid0] [raid6] [raid5] [raid4] [linear] [multipath]
[raid1] [raid10]
md1 : active raid0 sda5[0] sdb5[1]
78164032 blocks 64k chunks
md0 : inactive hda3[0]
116141824 blocks
unused devices: none
$ cat /proc/mdstat # with kernel 2.6.22.14 md drivers compiled inside
kernel (not as module)
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5]
[raid4] [multipath] [faulty]
md1 : inactive sdb5[1]
39102080 blocks
md0 : inactive hda3[0]
116141824 blocks
unused devices: none
$ cat /proc/mdstat
Personalities : [raid0] [raid6] [raid5] [raid4] [linear] [multipath]
[raid1] [raid10]
md1 : active raid0 sda5[0] sdb5[1]
78164032 blocks 64k chunks
md0 : inactive hda3[0]
116141824 blocks
unused devices: none
$ cat /proc/mdstat
Personalities : [raid0] [raid6] [raid5] [raid4] [linear] [multipath]
[raid1] [raid10]
md1 : inactive sdb5[1]
39102080 blocks
md0 : inactive hda3[0]
116141824 blocks
unused devices: none
All these test have been done with all 3 disks up, and with --run
option for mdadm in /etc/udev/rules.d/85-mdadm.rules.
You can see that md0 is never ran, and md1 (raid0) is sometime ran,
sometimes not.
Here, if I stop and launch manually the md, it works.
If I give the option --no-degraded to mdadm, it work always (if the
array is not degraded).
So, after this long story (sorry), my questions :
Do you think I'm totally lost, or editing this file is the good way ?
Is there a good reason why ubuntu's dev chose this --no-degraded
option for mdadm by default ?
What can I do more ??
The reason is because we don't want to degrade an array just because one
of the disks has not been detected yet. The proper solution is to wait
for either a timeout or manual intervention to go ahead and mount the
array degraded.
Why does the --run option never work, but --no-degraded work, even if
the raid array is not degraded ?
It seems like you suggest to be a disk not detected yet problem. How
could I workaround this ? Maybe a sleep 10 before launching mdadm ?
But why are the disk detected for md1 (raid1), but not for md0
(raid0), while it use the same devices (sda, sdb for md1, hda, sda,
sdb for md0) ?
Maybe it's a udev syntax problem (I didn't take time to study it) ?
Another question : you said I can run the array manually and launch
back the boot process. How can I do this last point ? running /init ?
Thank you !
Ben

Re: Adobe Acrobat Reader Plugin
It looks like the general consensus is to leave things the way they currently are. I will pursue the creation of a mozilla-pdf plugin, but I won't ask for it to be default, just for inclusion in the repositories.
