I'm not certain what is going on here. I am having trouble with getting a RAID0 working, and everything seems ok until it locks up and switches to readonly.

Code:
TheBeast gentoo # mdadm -D /dev/md0
/dev/md0:
        Version : 1.2
  Creation Time : Wed Jan 16 13:02:25 2013
     Raid Level : raid0
     Array Size : 228062208 (217.50 GiB 233.54 GB)
   Raid Devices : 3
  Total Devices : 3
    Persistence : Superblock is persistent

    Update Time : Wed Jan 16 13:02:25 2013
          State : clean
 Active Devices : 3
Working Devices : 3
 Failed Devices : 0
  Spare Devices : 0

     Chunk Size : 512K

    Number   Major   Minor   RaidDevice State
       0       8        3        0      active sync   /dev/sda3
       1       8       19        1      active sync   /dev/sdb3
       2       8       35        2      active sync   /dev/sdc3


All I can get from smartctrl is garbage... it is the same for sda sdb and sdc

Code:
TheBeast gentoo # smartctl -i -H -c /dev/sda
smartctl 5.42 2011-10-20 r3458 [x86_64-linux-3.6.11-gentoo] (local build)
Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net

Vendor:               /0:0:0:0
Product:             
User Capacity:        600,332,565,813,390,450 bytes [600 PB]
Logical block size:   774843950 bytes
scsiModePageOffset: response length too short, resp_len=47 offset=50 bd_len=46
>> Terminate command early due to bad response to IEC mode page
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.


Running fsck gets me this...

Code:
TheBeast mnt # fsck /dev/md0
fsck from util-linux 2.21.2
e2fsck 1.42 (29-Nov-2011)
fsck.ext2: Attempt to read block from filesystem resulted in short read while trying to open /dev/md0
Could this be a zero-length partition?


The strangest thing though is that it works fine if I reboot. But sooner or later it will lock up and do this. I don't have any explanation at all. What do you guys think. The drives all check out as good and they seem to work indefinitely as long as they are not in the array. I've already used dd to write zeros to all three drives. then rebuilt the array and I still have the same problem.

EDIT: oh yeah and after this thing happens dmesg fills up with a bunch of weird crap....

Code:
[21597.059294] Result: hostbyte=0x04 driverbyte=0x00
[21597.059295] sd 0:0:0:0: [sda] CDB:
[21597.059295] cdb[0]=0x28: 28 00 00 40 fd c9 00 00 08 00


This is just repeated over and over and some of them say sdb and some say sdc.

duby2291,

Tell us about the PSU (make and part number) and how the drives are wired to the PSU.
Does your PSU have one or two +12v supplies.

The smart data may be useful if you capture it before this happens too, when you can still get useful info from the drives..

A bit off topic here: Incidentally this was somewhat of a shock to me.

I took apart a failed Antec Truepower Trio 650 that a friend gave me, where "trio" implies that it had three 12V rails. When I traced the tracks on the bottom of the board, there were indeed three groups of 12V yellow wires... but they all eventually connected together to one common point after the main transformer/rectifier... The only thing that was truly "trio" was there indeed was three monitor points on each of the "rails"... but they were all the same output of the transformer...

Not exactly what I was expecting. But oh well.

Thanks for the reply guys. This is my power supply

http://www.newegg.com/Product/Product.aspx?Item=N82E16817153136

Also this is something new that only started after the first crash... This message didnt exst until after the first crash happened.

Code:

Ok and here is the smartctl for all three drives in the array

In recent times my "hack" RAIDs (one 4-disk SATA and PATA RAID5s) a disk "failed" when either power or the data connector loosened due to age or corrosion. It's worth to check. After cleaning the connectors and reattaching, the disk came back up fine. But in your RAID0 case, data is at risk... You may need to force-reattach the disk to the raid or recreate the RAID.

I have one 2-disk RAID1 in an SCA hotswap carrier. This has been much more reliable...

I don't have any data on it. It will be my gentoo / partition if I can manage to get it working properly.

I decided to replace the sata data cables on these drives to make sure that wasnt the problem, and since my PSU is modular I plugged in a different sata power cable in to the three drives. But the problem persists. It can't be the sata data cables or the sata power cables because I just replaced them after I saw your post but the problem remains.

duby2291,

Please post the output of
Code:
mdadm -E /dev/sd[abc]3


I should have asked for smartctl -a too, se we get to see the drives internal error log

Code:
# mdadm -E /dev/sd[abc]3
shows
Code:
Version : 1.2

That means you made your raid set with version 1.2 raid superblocks.

Your
dmesg:
[    7.214035] md: Autodetecting RAID arrays.
[    7.237521] md: invalid raid superblock magic on sdc3
[    7.237524] md: sdc3 does not have a valid v0.90 superblock, not importing!
[    7.266265] md: invalid raid superblock magic on sda3
[    7.266269] md: sda3 does not have a valid v0.90 superblock, not importing!
[    7.294346] md: invalid raid superblock magic on sdb3
[    7.294349] md: sdb3 does not have a valid v0.90 superblock, not importing!
[    7.294356] md: Scanned 3 and added 0 devices.
Is quite correct. Unfortunately, kernel raid auto assembly works only with raid superblock Version 0.9.
You have two choices remake the raid set with version 0.9 superblocks, or use mdadm in a initrd to assemble your raid before you mount root.
Remaking the raid will destroy the data it contains.

Where is grub?
Grub must be on a non raided volume or raid1 with version 0.9 superblocks. The reason is that grub just ignores raid at boot time.

Apart from looking a bit old
Code:
   9 Power_On_Hours          0x0032   068   068   000    Old_age   Always       -       28466
your drives look healthy.

None of these things explain the dmesg errors you get in the chroot.

Those drives are SATA II, thats 3Gbit/sec. Do you have a SATA II motherboard?
They should fall back to SATA I but its doesn't always work well. Put your entire dmesg on a pastebin site please.

Grub will be on sda1... sdb1 and sdc1 exist but won't be used they are only there to keep the partition table identical across all three drives. sd(abc)2 will be swap space with the same priorities.

OK and so if I use genkernel to create a initramfs with raid will that be sufficient? Or should I just recreate the array with the older version superblock?

EDIT: this is my motherboard. It doesnt say specifically but I believe ati sb710 SB does support SATAII

duby2291,

I've never used genkernel but I believe it makes an initrd containing mdadm if you ask it to.

We have not got to the bottom of your raid issue yet, your entire dmesg may well be useful as well as your lspci output.

Just to update you guys I think the problem has to be with the hardware somehow. First I wrote 0's to all three drives and then I created an array with the bios and installed windows on it. And I had exactly the same problem. I still don't think it is the drives. I think it must be the sata controller on the motherboard.

I had the same "600 petabytes" problem some time ago and it was the SATA controller that failed. What was funny, it kinda pretended to work for some time (minutes/hours) just after hard reset.
