Ubuntu Server on RAID 1 boot with RAID 1 data array.

[MattJo.]

Hello,


I would like to install Ubuntu Lucid Perfect Server with ISPConfig 3 onto a RAID 1 boot array and store the data on a secondary array also in RAID 1.

I have seen instructions on how to install the system onto a RAID 1, but not in the about config and also they don't say anything about whether I need to configure the onboard RAID controller (Intel Matrix).

I had originally tried to install onto an array configured with the onboard RAID, but the installation failed.

Any help would be much appreciated

For reference the board I am using in this build is a Supermicro X7SBL-LN2.

thanks,

Matt

Falko,

I was able to get server up and running with the RAID boot array--I actually was able to install and configure from scratch using the instructions on the main canonical site--initially had some grub errors, but apparently (at least with my system) this is/was solved by disabling the floppy drive/drive A/anything remotely related to floppy drives.

Anyway, I don't have a clue how to proceed with installing ISPConfig and its parts onto the data array. Or rather I would like to ensure that the users data is stored on the data array (ie FTP files, e-mails, web pages, databases, etc.).

Is there a simple command I can input while following your instructions for this or is this a larger endeavor than it would appear?

thanks,

Matt

OK, apologies for the overlap--I know this isn't the ISPconfig forum, but since this started here.... Also for my complete ignorance.

So, I have the RAID setup on both the boot disk and the data disk with Lucid installed. However, I think the install defaulted to using dmraid instead of mdadm. I know that mdadm by all accounts is preferable to dmraid--how can I tell which is used? If it is dmraid can I use your guide to change over to mdadm--or am I a complete idiot and misconstruing everything?

Second question. When I installed, I configured the DATA array to have the /home directory essentially out of--my ignorant--attempt to make sure that the FTP directories, e-mail database, etc were created on the larger data drive when I installed ISPconfig. So, assuming this was completely noobed-up what should I do to ensure that the databases, FTP, emal, etc.,. end up on the larger data array? Do I have to install and then move particular directories? What/how settings do I have to change assuming this is the case?

thanks much for your help.

Can you post the outputs of

cat /proc/mdstat

and

mount

? What's in /etc/fstab?

Looks good. You're using mdadm.
