The logs don't say that sdc is disabled.  Apparently the array doesn't
degrade and a rebuild is tried that fails when the kernel panics.  Have
you tried with a more recent kernel?

md driver - dropped disk still being used?

2011-07-18 Thread Sandra Escandor
Question:
I would like to confirm if I am interpreting the kernel log correctly.
The situation is that there was I/O going on to the RAID and then one of
the disks drop out - then the whole system completely hangs after
recovery finishes. I expected that the RAID would still be usable with 3
out of 4 disks (since it's in RAID10 configuration). Also, is this a
known issue?

My interpretation is the following:
1. There was a RAID member disk communication error with device sdc
(starts from ata layer).
2. The raid10 module handles this and disables sdc, then says that it
will continue working with 3 out of 4 devices.
3. md driver starts a recovery of the RAID (all four disks are still
physically in, but one has been disabled by the raid10 module).
4. After md driver says that the recovery is done, a kernel log message
shows that there is an unhandled error code from sdc (but sdc was
supposed to have been removed by the raid10 module, right?).

So, to get more specific with my question: If the raid10 module has
disabled sdc, why is there a kernel log message after recovery that
still involves sdc - no one should be talking to sdc, correct? I've
attached a kernel log snippet. I can post more if needed.

As noted by others that is the software raid (multiple device) driver.
Which makes me think you are using a bootstrapping kernel which has
everything built in.  In which case you might consider updating to a
tuned kernel for your hardware.  The tuned kernels implement most
device drivers as modules.

  apt-cache search kernel-image

Updating from the bootstrapping kernel to a tuned kernel is slightly
more complex than the typical package install.  If seeing the md
driver noise at boot is your only complaint then I would not upgrade.

According to the kernel docs, its software RAID. If you don't need it
and its a module, rmmod it, else change kernel.

Multiple-disk device driver.  I know it handles the kernel's software
RAID implementation, and I suspect that LVM is based off of it also.

It's one of those things where if you don't know what it is, you
almost certainly don't need it...

hello Rodrigo:

I've never seen problems with a floppy before. Thats a good one.

Try booting a DOS floppy if you can to see what happens.

Try resetting the CMOS to the manufacturers defaults. You may also
try removing the two hard drives on your second IDE chain for the install.
You can reconnect and initialize them once your up and running.

First - check your physical connections. You never know, something may
have shaken loose.

Assuming the FD controller is on the motherboard, you may want to
go to the manufacturer web site as see if there is a firmware update

   floppy0: no floppy controllers found
   md driver 0.35 MAX_MD_DEV=4, MAX_REAL=8
  
   Of course I've got a floppy disk controller. I've tried
  disabling it but the
   results are the same. I would appreciate any help because now I've been
   trying to install linux in this computer for almost six months
  and in the
   meanwhile I have to use linux on a 386.
  
   Please help me
  
   Regards

Re: md driver problem

1998-10-28 Thread Rodrigo Moya
Try booting a DOS floppy if you can to see what happens.
I've been using all this time Windows on this computer, and the floppy works
perfectly well. Usually, I start the installation process by booting with a
DOS disk, and then executing boot.bat from the cd.

Try resetting the CMOS to the manufacturers defaults. You may also
try removing the two hard drives on your second IDE chain for the install.
You can reconnect and initialize them once your up and running.
Well, now I've got four disks, but before I had only one and the CD and the
results were worst, since the installation process used to stop after
detecting the disks.

Assuming the FD controller is on the motherboard, you may want to
go to the manufacturer web site as see if there is a firmware update
What do you mean by firmware update?

Thanks very much

It doesn't seen to be a floppy problem but the md-driver seems to hang.
Sorry for me being stupid, but what exactly is the MD-driver?

Thanks very much

I think md is for the ramdisk.
how much memory is available ?
I've got 64MB of memory

Thanks

You certainly have lots of RAM.
Disconnect  the two HDs on the 2nd IDE chain and try again.

Check the manufacturers WEB site for firmware updates.

So, what does this mean? What should I change in the BIOS or wherever?

No, md is Multiple Device Driver.  Usually it's the NEXT driver that's
hanging, and that's almost always a SCSI driver.

md driver

1997-11-12 Thread RedHat Linux User
I am having a problem with the md driver

/dev/hda1 is the boot partition 300M
/dev/hda2 is a 127M swap partition
/dev/hda3 is a 127M swap partition
/dev/hda4 is a 3.3G linux partition   \
  |
/dev/sda1 is a 4.0G (whole drive) |
  |  /dev/md0
/dev/sdb1 is a 4.0G (whole drive) |
  |
/dev/sdc1 is a 2.0G (whole drive)/

then i do the following
/sbin/mdadd /dev/md0 /dev/hda4 /dev/sda1 /dev/sdb1 /dev/sdc1
/sbin/mdrun -pl -c4k /dev/md0
/sbin/mkfs.ext2 -c /dev/md0

When it finishes it says that block 49 is bad and that 1 - 55 must be good
to make a filesystem.  All drives will format by them selves.

3 months ago I put this machine together and it worked then.

anyone have any ideas ?

I don't have the documents right here, but are you sure that the
md drive can handle 13.3 GB partition?

A reason for the md driver to be able to handle 13.3 GB

Have you ran badblocks on /dev/hda4 ?
