[CLOSED]diskdrake crash with RAID structure left on disk

[mailedfist]

I have been ignoring this issue for months but was hoping that it may be resolved in Mageia 2. Sadly not, so I thought I'd post on the forum again in case anyone has any bright ideas.

I was running software RAID 1 but decided I wanted to go to hardware instead, so installed a hardware RAID card which works fine. However, the software RAID controller still has one RAID drive connected. I can't tell it that it is no longer RAID without completely reformatting the disk, which I don't want to do, so it complains there is a RAID structure on the disk on each boot, but that's no big deal. What is a big deal is that diskdrake crashes so I can't use the nice GUI I've used for the last umpteen years to manage my partitions.

Fdisk -l will help us, also what did use use to create the raid, the bios or a util.

As I recall, I just connected the second drive and switched the RAID controller BIOS into RAID 1 mode.

/dev/sda has never been RAID.
/dev/sdb was half of a RAID 1, and is still connected to the same controller.
/dev/sdc is hardware RAID 1.

Sorry that the fdisk ouput is so verbose - even the normal drive gets special treatment for some reason (and always has done):

Partition table entries are not in disk order

Im sorry your just going to have to take a hit on this, buy a usb external drive, back it up and

Reformat.

Its just not worth the agro, and you possibly need a backup device anyway.

And theres a risk that not backing it up and converting could loose your data

Its just not worth it.

Regards peter

I backup to LTO tape once a week. Getting the data back isn't the problem.
The issue is that, despite trying on-and-off for months, I cannot get my machine to boot straight to the HW RAID drive - grub doesn't support it. Hence, /boot has to be on one of the other drives and it is currently on the one which was SW RAID. Every time I try and move it to the other one, this stupid mapper nonsense comes into play and it changes the drive IDs and stops with a kernel panic.

I'll stick with no diskdrake for now until I can get a clear 72 hours or so to do battle with grub again. My next machine will not have a JMicron disk controller - I want /dev/sd* to be what it says, not some silly other name!

[wintpe]

re hw raid not supported,

can you let us know what hw raid you are using.

and for example does it have its own boot rom/config rom.

have you set in the bios of the computer to boot from other rather than sata or cdrom.

I ask this as many a raid/slot in additional harddisk controller have i used and never have i not been able to boot from it

unless its one of those joke raids.

regards peter

[mailedfist]

Its a HighPoint 622.

lspci gives
04:00.0 RAID bus controller: HighPoint Technologies, Inc. Device 0622 (rev 01)

The kernel copes with it fine using dkms. The machine BIOS quite happily starts grub from it, but grub gives up when it is loading linux.

All I have to do is move /boot to another drive and change the BIOS to boot from that. grub then loads the kernel fine, and it then recognises the RAID drive and the rest of the linux filesystem runs from the RAID array with no problems.

[wintpe]

I had one of those rocketraids from highpoint, alot of money and damm useless.

still got it and dont use it.

so i understand you point of view.

with modern CPU's software raid is just as good, where i work we use software riad on all the SUN Microsystems systems and it does not affect there performance at all, you can get a free version of veritas volume manager that will manage a limited set of luns.

or you can use one of the many opensource mirroring software.

just use a standard disk controller.

alternatively the 3ware controllers are good, there proper raid, and if your PC is PCI-X bus there realy cheap on ebay, i got a 12 channel sata for about £50 for my file server I think its a 9660.

just some ideas

regards peter, and sorry i could not help you solve it.

[mailedfist]

No problem Peter, thanks for the input.

Apologies for the delay in responding, but I have a bigger problem at the moment. My 4 year old motherboard has decided to develop a fault. I got a kernel panic in the middle of editing in libreoffice (not something I would expect) and now I sometimes don't get as far as POST beep or, if I do, it locks up at various points before getting into grub. So, this thread will be paused for a while until I either find the dry joint/broken track/loose connection or bite the bullet and buy a new board.

[wintpe]

ok, i know this is off thread, but since you have not started a new one.

1:check that the cpu to heatsink is a good connection and that the fan is running and clear of dust.

2: if you can remove a dimm and run with one then swap that if it still does it.

memory and overheating cpu are the most common cause of system failure on the mb, disk bad blocks are probably the highest cause.

This thread is likely to never be completed - the motherboard on the PC in question appears to be dead.

In answer to the previous suggestions relating to that, no (measured) part of the system has ever been above 45 Celsius. I've never (in my 30 years plus of working with computers) known memory stop a machine from doing POST, and as far as disk doing it - no way, Jose. However, the symptoms are entirely consistent with failing capacitors and it turns out that the motherboard in question is prone to capacitor issues (wish I'd know four years ago that they were fitting ultra-cheap electrolytics!). It has progressed from intermittent to permanent. I'm not a happy bunny.

When I get the replacement machine up and running, I'll see whether I can reproduce the thread topic problem but I suspect it was entirely related to the JMicron RAID controller which does not exist on the HP.

[martinw]

Having just replaced my motherboard, I've encountered the same problem with a disk that was long ago part of a RAID array. The command

Code: Select all

dmraid -rE


fixed it for me. Note that unless you specify a device path, all discovered RAID structures will be removed - so go carefully!
