NGFileSystem

Postby dstastny » Sun Dec 18, 2016 3:51 am

Hello new X5000 owner. My new machine came with filesystem configured to NGFileSystem. Since there a are multitude of available filesystems I cant find any reference to this NGfilesystem vs say SFS.

Thanks for any info and look forward to asking lots of questions :)

NGFileSystem is a new file system that has been in beta test now for a couple of years as it grows and evolves. It is being released with the X5000 machines as a new and more modern alternative to FFS.

NGFS (as I call it) is roughly the same as SFS in performance in most respects. There are some tests where SFS does better and some where NGFS does better.

The main advantage of NGFS is that is being maintained and continues to evolve. That is why NGFS has been released in a beta state with the X5000. You will find some documentation for it in SYS:Documentation/NGFileSystem/NGFileSystem.doc.

If you have any other questions, just ask away...

Will it be part of an update for X1000 users or de we have to wait for AmigaOS4.2(==forever)?

I can't say, that's not my decision. I *think* they want to keep it to be part of OS4.2, but that intention might change...

iiuc Jörg is doing the development?

Can you say if this is based on his SFS or JXFS?

Or this is a whole new take on a FS from scratch?

...while i don't really know anything about FS the things in your link at least sound good :-)

Thanks for the info

Hi, Tony!

According to the docs, "The system volume can be formatted as NGFS and the NGFS volume booted on the X-1000 and X-5000 machines."

I tried this today on my X-5000 and couldn't get it to work. The partitioning, formatting, and installation steps all worked perfectly, but the net result after several attempts was an unbootable volume. I made sure the Automount and Bootable flags were set, tried various partition sizes, re-installed the RDB, etc. No luck.

Booting from CD, I was able to access the files on the target volume just fine, so it seems like it's only U-Boot that doesn't recognize it for some reason.

Anyway, I'm up and running with a small FFS boot volume for now, but I'm wondering if my firmware is out-of-date, booting with NGFS isn't supported yet, or perhaps something else is wrong.

EDIT: My board's firmware contains U-Boot 2014.4-0013.
