Metadata with Large ADS

[KenJyn76]

Hi, I'm trying to convert my data drive (mainly contains games) to btrfs, but am getting the following error:

Skipping overly large ADS $Extend$RmMetadata$Repair:$Corrupt (9216000 > 16215)
Skipping overly large ADS $Extend$RmMetadata$Repair:$Verify (4096000 > 16216)
Skipping overly large ADS $Extend$RmMetadata$TxfLog$Tops:$T (1048576 > 16221)

I can't seem to find any way to resolve this, do you know of a way? I've tried a couple fsutil commands I found on the web with no luck.

Thanks!

It's not an error. Anything in the \$Extend directory is skipped - it's just that the check to do so is after the check for the stream size. The message ought to be suppressed in this instance, really, and will be in later versions. You can ignore it.

The issue is that we map NTFS Alternative Data Streams onto Btrfs extended attributes, but the former can be any size while the latter are limited to just under 16 KB - which is a problem more in theory than practice.

Strange -- I assumed that was the error, since that was all that was thrown before ntfs2btrfs stopped working. Something does seem to be broken, though. It throws that message, prints "0.1%" to the next line and completely ends.

Oh, right - it must be crashing on something then. Can you post the full output here please?

PS C:\Users\user\Desktop> .\ntfs2btrfs.exe D:
Skipping overly large ADS $Extend$RmMetadata$Repair:$Corrupt (9216000 > 16215)
Skipping overly large ADS $Extend$RmMetadata$Repair:$Verify (4096000 > 16216)
Skipping overly large ADS $Extend$RmMetadata$TxfLog$Tops:$T (1048576 > 16221)
PS C:\Users\user\Desktop> (0.1%)

This is the full stdout that I get from PowerShell and bash, if run in Linux. CMD gives nothing at all.

I have the same issue, (or at least I believe so).

$ sudo ./ntfs2btrfs /dev/sda1

gives my following output

[sudo] password for admin: 
Skipping overly large ADS \$Extend\$RmMetadata\$Repair:$Corrupt (10485760 > 16215)
Skipping overly large ADS \$Extend\$RmMetadata\$Repair:$Verify (4194304 > 16216)
Skipping overly large ADS \$Extend\$RmMetadata\$TxfLog\$Tops:$T (1048576 > 16221)
Attribute not found.

after It returns with POSIX exitcode 1.

Could you give it a go on the latest version please?

Could you give it a go on the latest version please?

Tested a spare HDD and it seems to work fine. Before I couldn't get it to work anywhere. I'll test it on a drive with more data shortly.

On the SSD I wanted to convert, I'm getting "Error assigning space to file. This can occur if the space bitmap has been corrupted. Run chkdsk and try again."

chkdsk doesn't find anything. Might be because the original was one disk and currently I'm trying to convert a RAID 0 array?

Is this still an issue on today's version?
