Post FreeNAS and ntfs-3G errors? *edited*
Ok so I'm new to this FreeBSD stuff, this is my first venture into it. I'm not sure what info is needed so I'll just post what I know.

I built a FreeNAS box and its booting FreeNAS from a USB thumb drive. It has 2 500Gb SataII drives that were originally inside of a Vista box and were full of data. I did not format them when I set up FreeNAS, I set them up to keep the original data and mounted them as they were.

The box is up and running fine, and I have both drives mounted and it appears I can view all the files. However when I look at the error logs in FreeNAS it says:

ntfs-3g[913]: Skipping unrepresentable filename (inode 393): Illegal byte sequence

So I have poked around and I have a basic understanding of what is going on. I am assuming I have a file named with a character that ntfs-3G doesn't recognize? But I am unsure how to locate the file and correct it. Do I need to take out the HDD's and put them back into the Vista box to see what file I am missing in the FreeNAS box? I only see this error message once, so I am assuming it only 1 file.

Am I headed in the right direction here?

OK, now, I have cleared all the logs, and rebooted but I no longer see any errors in the log. I am unsure if I even should be seeing an error now if there is one. I thought that ntfs-3G loads at boot, so shouldn't I see an error message by now if there is one? I did delete the old hidden $recycle bin$ files from when the drives were in the Vista box, perhaps those were the problem? Do I need to unmount and remount to get the errors?

Sorry my post is so long winded, I don't know a whole lot about this stuff yet.

Alright, well the error still logs, at random times, propably whenever freenas tries to update a file list automatically because it happens during times I am sleeping or not at the computer. I am worried that the file is not being shown on the drives, and I have no idea what file it is because the drives have a LOT of files on them. Anyone have any ideas here? I am on the right track with my assumptions?

Please see this: http://ntfs-3g.org/support.html#locale3 though I'm not sure if it also works on FreeBSD.

You could find the file like
Code:
find -inum <INODE_NUMBER_IN_THE_LOG>

If it's shown then your problem is solved.

If you have ntfsprogs installed then you can also run
Code:
ntfsinfo -fi <INODE_NUMBER_IN_THE_LOG> <DEVICE>

to see the file name.

Good luck and let us know how it goes!

Hmmm, alright, makes sense. I read the article, but I don't think it applies to my problem simply because its only one file. (inode 393)

I could be wrong, I don't know jack about this OS.

Now when you are telling me to enter those commands, where am I supposed to enter them? There is a command function in FreeNAS, but when I try the commands it does nothing, I don't get a message of any type.

It always applies for that error message.

Try to add the locale= option to the relevant line in /etc/fstab then umount/mount the volume. Remount is not supported.

First off thanks for helping me.

I am able to browse thru FreeNAS and I can see the /etc/fstab file you mention. If I open it for editing I see:

/dev/da0a /cf ufs ro 1 1

What exactly should I be changing it to?

By the way this is my logs timestamps...

NTFS-3G should have soon built-in support for national filenames. That should solve your problem on FreeBSD too, if FreeBSD doesn't support 'locale'.

It may support it, I just don't know much about it.

When you are telling me to edit the /etc/fstab file, what exactly should I be editing?

My fstab looks like this now:

/dev/da0a /cf ufs ro 1 1

This setup has been running for about a week now, and I haven't changed any settings. I was getting the Skipping unrepresentable filename (inode XXX): Illegal byte sequence error every day.

Now suddenly it has stopped producing this error and I see this in the log file every time I reboot:

Nov 5 23:35:47 nmbd[26053]: [2008/11/05 23:35:47, 0] nmbd/nmbd_become_lmb.c:become_local_master_stage2(396)
Nov 5 23:35:47 nmbd[26053]: *****
Nov 5 23:35:47 nmbd[26053]:
Nov 5 23:35:47 nmbd[26053]: Samba name server FREENAS is now a local master browser for workgroup WORKGROUP on subnet 192.168.XXX.XXX
Nov 5 23:35:47 nmbd[26053]:
Nov 5 23:35:47 nmbd[26053]: *****

What does this mean? Does it mean that since FreeNAS is a LMB that the file I was getting the Skipping unrepresentable filename (inode XXX): Illegal byte sequence error from could be on any computer in my workgroup? I am lost here now...
