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!
Yes, flash content is removed and I am never going back to OS6. Re: booting w/o USB, I just used Ubuntu install tool, created ext4 100GB partition on one of four SATA drives, told it to mark flash as boot drive (basically where to put grub) but install linux on 100GB partition. After that, NAS booted itself w/o any external drives. But Ubuntu is a bit too much of a system so right now, I am tinkering with DSM.
P.S. You need to switch tty from 9600 baud during "BIOS" phase to 115200 baud during Ubuntu installer boot phase (or just configure it to 115200, and hold "backup" button until you see it booting. Afterwards, it is easiest to tell installer that you want to use SSH and continue from there.
