(Haiku developer here.)

I would trust the NTFS driver pretty implicitly at this point both for read/write; it's based on NTFS-3G, and following the rewrite I did of the Haiku-specific parts of it in late 2021, appears to be very solid in testing.

The EXT2/3/4 driver is also very good, but there may be some issues remaining there. However I haven't heard reports of it destroying data.

The FAT driver, on the other hand, has some cases where it has been known to corrupt directories. It could probably use a rewrite; most of its code dates to the 1990s...

Those are the "big 3" of other filesystems, anyway. I don't think there's a status page for all of them.

Thanks for the heads up. The only current issue with ext4 that I found was https://dev.haiku-os.org/ticket/16392 which makes me a little nervous and I don't think I will be plugging in my primary backup drive just yet but at least it can now deal with journaling on ext4, progress. For now I can deal without that but this is the thing that has historically caused me to take Haiku off the computer.

ZFS and Btrfs both are very good these days?

Can linux mount the Haiku version of BFS? Seem to recall that this was an issue the first few times I tried Haiku and it was buggy and unreliable but don't quite remember or recall trying it since. Searches are not pulling up anything useful. If not is this something Haiku is planing to work on or are you just going to let linux take care of that when ever they get around too it?

A 3 year old ticket with only one reproduction from 2 years ago, and it appears to have been fixed in the interim, and now the ticket has been closed by the main developer of the ext2/3/4 driver. I wouldn't be too worried about that.

That's probably a good idea anyway.

> but at least it can now deal with journaling on ext4, progress.

I think it's supported journaling for many years, I don't believe that to be a new feature.

> ZFS and Btrfs both are very good these days?

We don't support ZFS at all, and btrfs support is read-only (there's experimental write support but it's disabled in default builds still, I think.)

> Can linux mount the Haiku version of BFS?

Yes, read-only with the upstream Linux driver. There is a way to get read-write support with Haiku's driver under FUSE, however it's not very performant to say the least.

FWIW, it looks like they just closed that ticket now. I guess another developer saw this comment.
