linux affs 4GB limit

[MarkWatson]

I just backed up my Amiga HDD to Linux using a USB to IDE adaptor. I can mount the first partition on the drive no problems with 'mount -t affs -o loop partition.img somewhere'. However I get told there is a bad superblock if I mount the other partition. I can read it fine using the hard file support in UAE so I think the image itself is fine.

Does the Linux affs support >4GB partitions 'out of the box'? If not has anyone coded a patch they'd care to share?

If not then I guess I'm best off mounting a linux folder in uae and then copying or arching everything there to make it available in linux?

Appreciate any help. Had an '060 in my A1200 and since I sold it I have 100KB memory left after booting! So thought I'd at least keep the data I have on there somewhere else safe for now...

Thanks,

Mark

Not entirely sure, but my understanding is that Linux affs hasn't been updated in absolute ages. So it probably is running into some old bugs, possibly >4GB-related.

If you need to pull files from your disk image, another option might be to copy from the hardfile to the directory-based filesystem in UAE. You'll lose your protection bits, though. You could also create some <4GB hardfiles and copy to those via UAE.

You'll lose your protection bits, though.

You'll lose them anyway if you mount the file system in Linux.

Thanks. Good to know its an affs issue and I'm not just being a muppet/have a subtly corrupt image. I guess I'll either try the copy to smaller hard files or lha them to a directory based filesystem - to keep the protection bits:-)

Wonder how much needs changing to support >4GB partitions in the Linux driver. Are you aware of any docs on the fast file system that describe the filesystem changes?
