Topic: Problem adding second raid drive

[morpion]

Morning all,

After problems with myprevious install I have done a clean install of 7.4 onto my server. I now want to add a second HD which is identical to the current one. I have gone into the console and clicked on option 5 and asked it to add the disk. After a blue screen for a few seconds it goes back to the menu but does not start the raid recovery.

I have checked my message log and attach it as follows.

I have tried deleting the partitions and this command

Code: [Select]

dd if=/dev/zero of=/dev/hdc bs=512 count=1 but it still comes up with the same Error 17 Cannot mount selected partition.

Can anybody please help me with this?

Many thanks

Is this a new drive or has it been used previously for another OS ?

What sort of controller are you using ?

[morpion]

>Is this a new drive or has it been used previously for another OS ?

It's been used before as it was in our old Windoze server

>What sort of controller are you using ?
I'm sorry but I don't know what you are referring to

Mike

[p-jones]

Hard disk controller ??

The logs would suggest a problem with the drive. Its making all the right noises but not achieving the right result - possibly due to some proprietry MBR on the drive.

Have you tried running a utility accross the drive that will completely wipe it clean including the MBR then adding it to the system ?

Otherwise suggest a new drive - they are cheap as chips these days. You can spend far more in time trying to resolve this than the cost of the drive.

If it still doesnt play nicely with a known good (and clean) drive, then you need to take it to the bugtracker.

[morpion]

Thanks for your swift suggestions.

Have you any suggestions for this as I am very new to SME and Linux so still finding my way!

Thanks again

hi

as suggested in the log you posted, you should do

Code: [Select]

dd if=/dev/zero of=/dev/hdX bs=512 count=1

where hdX is the hd you want to add.

be carefull, be sure to use the right hd (hdc as I understand)

hth
ciao
Stefano

[morpion]

Thanks Stefano

I have done that but get the following:

Code: [Select]

[root@cfs4 ~]# dd if=/dev/zero of=/dev/hdc/ bs=512 count=1
dd: opening `/dev/hdc/': Is a directory
[root@cfs4 ~]#

I'm confused!

[Stefano]

please re-read my post and check your syntax.. there's a '/' after hdc that shouldn't be there..

Stefano

[p-jones]

There is nothing linux specific about this.

[morpion]

Thanks Stefano. I hadn't realised what a problem one little / could be!

I have done that and it gave me

Code: [Select]

[root@cfs4 ~]# dd if=/dev/zero of=/dev/hdc bs=512 count=1
1+0 records in
1+0 records out

I have now rerun option 5 to add the disk to the array and got the same problem.

Am I looking at a dead disk here?

Many thanks

[Stefano]

please check the size of the hds..

in my experience 2 'identical' hds could be of different size

Stefano

[morpion]

I have run fdisk on my two disks and have the following data

Code: [Select]

Disk /dev/hda: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1          13      104391   fd  Linux raid autodetect
/dev/hda2              14       38913   312464250   fd  Linux raid autodetect



Code: [Select]

Disk /dev/hdc: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hdc1   *           1          13      104384+  fd  Linux raid autodetect
Partition 1 does not end on cylinder boundary.
/dev/hdc2              13       38913   312464287   fd  Linux raid autodetect


The sizes look the same but it is interesting to note that the block size on hdc are different. These are the result of it creating the partitions itself when I select option 5 to rebuild the array.

I would have thought that the system would partition it correctly and be the same as the other disk?

Please note what it says every time you create a message here:

Don't report problems here - Please report bugs and potential bugs in the bug tracker

[morpion]

Yea...thanks Charlie.

I appreciate that but I did that last time and my bug was closed as not being a bug so I am none the wiser!

Is there a forum around for things that aren't bugs (because SME server is great) but are problems which newbies like me can ask for help for from more experienced people?

Many thanks
Mike

...I did that last time and my bug was closed as not being a bug so I am none the wiser!

Well that's when you come back to the forums for "non bug" support.

Is there a forum around for things that aren't bugs...

Well in the case of this forum post, you are now being asked to go to the bug tracker, so please do that.
Your other problem (lodged at bugzilla) was different to this one, so don't prejudge the outcome.

If your problem gets resolved there, then good, if not then come back to the forums here with your issues.
