Amahi - Linux *RAID question*

[ImJay]

I came across Amahi and I actually like how it looks.

What I want to know is, will my RAID setup be lost if I were to upgrade/install a new OS?
I have one 60gb harddrive for the OS
and four 2TB drives in RAID 5

Will installing a new OS/upgrading Ubuntu remove all data and get rid of the RAID? Or can I just add the configuration into a new OS without wiping all data?

No installing a new OS to the 60gb drive will not magically erase your data

Will I have to un-mount the drives and create the RAID setup again?
Or will the new OS just pick up the RAID config and mount the drives as such?

its easy using mdadm, to set up your raid config again but i dont know if it will automagically 'pick up the raid config'. Thats a distro specific question you should ask in the amahi forums.

There are a few ways to add storage to Amahi, however, RAID is done at the distro level -- Ubuntu for the latest release or Fedora for the previous release (and the next one) of Amahi.

In Amahi, you create shares and point them to wherever the storage is -- whether it's RAID, using Drive Pooling (using Greyhole in Amahi) or a local LVM partition or just a regular partition.

As skittle mentioned, mdadm is great, if you know what you want and how to use it.

Thanks for the kind words for Amahi

If your RAID was setup by the BIOS or by an add in card, then any major modern OS should pick it up so long as is has the drivers for the RAID controller. Even if you have to add in the RAID drives later to the OS, it should not effect your data. If you have a hardware RAID the RAID controller manages that RAID not your OS. That being said it is always safest to backup your data.

If your RAID is a software RAID like those created in the OS whether Windows, Linux, or something like FreeNAS the data will be lost.
