Sata Raid

[gbrook]

Is Sata Raid 1 supported (Centos Raid SW) during installation?

Yes, you should enter in "advanced" mode when you're installing.

Just type "linux advanced" in the first installation screen.

 

[gbrook]

Thanks for that.

I will try on the next reinstall.

I assume it is fairly straight forward for a relatively newcomer to linux

It is the exact same partition tool you use on Red Hat, CentOS or Fedora.

Hi Edgar

I typed linux advanced at the installation prompt and it just went through the usual - keyboard type - timezone and password and didn't do anything in regards to setting up the two disks in raid

Did I need to do anything else?

Regards
Garry

 

[gbrook]

OK

The the command is actually:-
linux ks=cdrom:/ks_advanced.cfg

The install starts normally but there is a new screen for partitioning and RAID

I assume that the custom partitioning is used but when I get in there I am lost as to setting up the partitions as I am new to the linux world

Is anyone able to help with typical settings for the partitioning etc in order to get RAID 1 going?

Cheers

This links might help you:

BTW I manage to get the partition menu when typing "advanced" on the installation menu instead of "linux advanced".

Hi,

I am trying really hard to get away from TrixBox and the shenanigans going on over there but the only stumbling block left is that I wish to always have 2 80GB (minimum) SATA Drives in RAID 1.

I also actually prefer the Elastix GUI and as I use Rhino Cards the installation is very simple in all other aspects. Probably the only thing I prefer in TrixBox then still is the File Configuration Editor.

The RAID is really easy to do in TrixBox as it is just a command line option "sataraid" and it goes off and does it all itself and then installs TrixBox.

I am getting there with linux but not enough to manually setup the RAID 1 in the Elastix installation (mount points etc). Is someone able to provide in depth help as to the steps and settings in the setup box for partitions and RAID during the Elastix installation?

A small payment could also be made available.

I could also then document these steps for adding to the Documentation for others

Cheers

You have to be more specific, you are trying to use software raid witch linux provide or you are trying to use the motherboard raid ?
If you are using the motherboard you have to type "linux sata-raid" if you are trying to use linux software raid you type " advanced "

hope that help

Hi Garry,

Have a look at this thread, it is the most comprehensive document I have come across to date.

Please let me know if it helped you.

Thank you - that is exactly what I was looking for - worked like a charm.

I am now TrixBox free

Hi Garry,

Nice to hear that it worked for you and you have go rid of :evil: T

 

[martinparks]

Thank you as well. I have been looking for this. Very easy to understand and fallow.

As a test. I unplugged "sdb" the system worked just fine

I then unplugged "sda" it booted to GRUB hard drive error screen.

What does this mean? Does it mean that the RAID is not working or am I missing something ?

 

[nothings_found]

It means that GRUB is only installed on the MRB or sda and not on the MRB of sdb

You will need to manually setup the MRB on both drives after a software raid setup.

I'm running my Elastix server on a RAID 1 (BOOT 4 Drives) and my swap, /, home on a RAID 5 (4 Drives)

Do this to install the MBR information to both drives.

# grub
grub> device (hd0) /dev/sdb
grub> root (hd0,0)
grub> setup (hd0)
grub> device (hd0) /dev/sda
grub> root (hd0,0)
grub> setup (hd0)
grub> quit

And then test again.

Thank you very much, that was it and the test went fine. I can unplug the drives and all is working as it should.

Thanks again "nothings_found"
