Support for Software Raid (mdadm) #1210
Description
Is there an existing issue for this?
- I have searched the existing issues and found none matching what I'm reporting.
Is the feature related to a problem or existing issue?
The installer UI does not recognise my mdadm assembled array as an install option. Instead I just see the drives themselves and have no way to install on my raid device.
Please can you add the functionality required to install onto an mdadm raid array.
Describe the feature, why the feature matters to you, and what benefits the feature will bring about.
The ability to install to say /dev/md0 has always existed when using ubiquity, but this new installer fails to see the RAID device. I normally have 4 drives in a RAID 0 configuration, allowing for really good I/O and linked up storage capacity. I have had to install onto a single drive for now as I adopt Ubuntu as my new desktop of given its functional weyland support.
Describe any alternatives you've considered.
I have tried to build the array manually after the install by backing up the system drive, building the array and then copying the files back to the new array, chrooting in configuring mdadm and grub for boot. This failed however, and I have not been able to determine why as of yet.
Additional context
Having better support for Software RAID built into the installer to the point where it manages grub and the re-assembly of the arrays at boot would be an amazing enhancement on what existed in ubiquity however, the most immediate challenge it to just get the installer to see the RAID devices.
