Any interest in a bounty for a native ext2/ext3 file system?

@salass00

Yes.

Progress update:

Yesterday I started work on diskio.library, a library which will act as a layer between the filesystem (NTFileSystem3G, FuseExt2FileSystem) and the storage driver (usbdisk.device, #?ide.device, ...) and implement a relatively simple read/write block cache .

In Linux block caching is implemented at a level below the filesystem implementation but in AmigaOS ports of FUSE filesystems I've so far had to implement block caching separately in each case. This is what diskio.library intends to get rid of, this unnecessary and wasteful duplication of code and effort.

@salass00

There is a "diskcache.library.kmod" in the kickstart directory (SFS and JXFS are using it, I think).

But there is no documentation in the SDK, at least I didn't find one.

@Gazelle

I am aware of it but since there's no documentation or even include files needed to use it available it's not an option.

If using diskcache.library had been an option I wouldn't have bothered writing the block cache in NTFS3G in the first place but it seems that the author of this library doesn't want it to be used.

@salass00

Quote:It's no option for your file systems because they are usually used on USB media. diskcache.library can only be used for HD partitions, it doesn't support removable media/devices.

@joerg

Thanks for clearing that up.

@salass00

You could have used the FFS2 cache (fs_plugin_cache) for your file systems, since it's using separate caches for each partition, unlike the shared cache for all partitions on all devices in diskcache.library, there should be no problems with removable media with it.

filesysbox.library 53.24 is now made public via AmiUpdate.

Source code is available at:

@salass00

Just wanted to say thank you for this addition, hopefully more fs will surface

IIRC some people were interested in exFAT support that may be possible with a port of fuse-exfat:

I've looked over the source code and it doesn't look like it would be too much work.

@salass00
By curiosity, what is the progress status of your port of ext2/ext3 fs ?

Sorry if I have missed a post on this thread...

@zzd10h

I think you might get in to problems whit EXT2/EXT3 on the Amiga side, because AmigaOS can't know what USER or GROUP id to use when saving or editing files on the Amiga side, beside Linux uses use different protection bits.

It's working and with beta testers. The biggest issue preventing a release ATM is the very slow sync operation which blocks any access to the filesystem while it's running.

Thank you for the progress report.

Hoping that you will suceed to debug this problem !

@zzd10h

Just to be clear it also applies to fuse-ext2 on other OSes, it's not AmigaOS specific, although it's less of a problem on other OSes as this operation only has to be done when the filesystem is unmounted.

ExFatFileSystem now compiles but is still untested as I haven't been able to create an ExFAT partition yet. Trying with Windows XP it will only allow me to format the new partition as NTFS and while GParted in Ubuntu 12.04 does list exfat as a filesystem choice it's ghosted and can't be selected.

After installing an update linked to from the wikipedia page on exFAT I was able to format a partition on my USB harddisk as exFAT.

@salass00

Things have never been better in Amigaland!

@Salas00
Cool ! Don't test speed at moment ? Maybe will be even faster than cross-dos/fat ?
