Error converting NTFS

[Krutonium]

Basically, having read the warnings, I am attempting to proceed with converting a 6TB NTFS drive to EXT4.

Everything looks fine up until this point:

06:33:49 fsremap: ERROR: ff_posix_fibmap(): error, dev_block_count = 11720777728, file_block_count = 11720777728 overflow type (int): File too large
06:33:49 fsremap: ERROR: failed to list file blocks with ioctl(FS_IOC_FIEMAP): Operation not supported
         
06:33:49 ERROR! fstransform: command '/usr/bin/fsremap -q -n -- /dev/sdf2 /tmp/fstransform.mount.1718/.fstransform.loop.1718' failed (exit status 229)
                this is potentially a problem.
                you can either quit now by pressing ENTER or CTRL+C,

I assume I should be concerned, so I am wondering what the best course of action would be here.

Hello Krutonium,

Short version: HIC SUNT LEONES - there are lions here, don't try it.

Long version: converting NTFS comes up relatively often, but is not supported for a long list of reasons.

One reason is that it's EXTREMELY slow.

Another is that it's limited to ~2TB due to missing support for ioctl(FS_IOC_FIEMAP) both in FUSE ntfs-3g driver and in Linux ntfs filesystem.

And there are other reasons to...

I tried to solve or work around the problems of NTFS conversion several times, and until now I did not succeed.
