Just installed Ubuntu Server 24.04.4 on Ultra4, how to organize partitions?
Hi, I tinkered with trying to get SMB multipath working on OS6, but as Debian Jessie has not been supported for many years I decided to try to load modern Linux distro on my Ultra 4. After lot o...
OK, I will comment myself as I got it all running. Ubuntu boots just fine on Ultra 4 internally now. No need for USB sticks of external drives.
The trick is in doing disk configuration right once you boot from Ubuntu USB installer. Chose "custom storage layout".
- Remove all partitions from all drives (except USB stick). Yes, that includes internal 128MB flash...no going back now
- Create MD0RAID5 or RAID1 partition across SATA drives as you fancyf, format ax ext4 (btrfs might work too, haven't tried)
- Mark 128MB flash as boot (this will place grub on it)
- Mount RAID partition as /, this will place everything on RAID5.
Once you press "Done" it will start doing the work. Be prepared, it will take loooong time. Copying files from USB takes time, but so does creating parity for RAID5 array. We are talking hours and maybe days.
Also, chose quality USB stick. I had it abort after few hours due to USB being corrupt.
I now have ReadyNAS-shaped Linux server and it rocks!
When the time comes, you may want to put the step-by-step in a separate thread. Many will be very interested as to how you boot from the flash and then pass control to the drive(s) since booting directly from the drives isn't an option. That's a step you don't see in most currently available posts on alternate OSes for ReadyNAS. I've given people general info on how Netgear does it, but I've never seen a post where it's actually done with an alternate OS and I've never tried an alternate OS myself.
Did you back up your flash content before you proceeded (with dd is best, but at least the vpd file)? If not, and you deleted the vpd file, then you lost the possibility of going back to any ReadyNAS OS.
