Copying files from NTFS to BTRFS of 2GB or more hangs completely
File copy transfers of 2GB or more hangs the transfer and Windows itself, sometimes even leading to a BSoD.
What version of Windows is this on? (Try running winver.)
Can you get it to generate a minidump for the BSOD?
I couldn't reproduce this on Windows 10... I'll have to close this unless you give me the details.
Apparently, this bug happens on Windows 10 20H2, and doesn't happen on LTSC which is based on Windows 10 1809.
Sorry for late reply. Will try to post a minidump someday when I get the chance.
Here happen the same issue, Windows 10 20H1 64. Copying files 2 GB freeze Windows Explorer and even removing the drive (if using external drive) the freeze continue and need restart the system. Impossible copy my files from external driver BTRFS to internal drive NTFS using Windows Explorer. If using FastCopy utility not happen the problem and is possible copying all files without hangs on system.
@maharmstone you wanted details, here are some :)
I can confirm this on Windows 10 2004, latest driver version (1.7.6). I was initially able to copy 60GB of data onto it no problem (using the partition for my steam library). But now, whenever steam updates games I observe the same behaviour described by others in this thread and in #346.
At this point I have already encountered the bug twice, both times while steam was doing updates, so it might be reproducible if I just wait for steam to update something. I have not had a BSOD yet though.
The partition resides on a spinny-disk, was formatted using mkbtrfs here on Windows and has exactly one subvolume containing all the data, and there is one snapshot of this subvolume. Compression was set to zstd right after creating the subvol (but not forced). Steam is the only thing on my system using this partition (also no swapfile on there).
An interesting nuance I observed (not sure how helpful though) is that windows task manager shows about 3.5GB of "Modified" RAM in the Memory tab while this bug is "in progress", so to say. That value has been the same both times. What's also weird to me is that all disk IO (yes, writing and reading) of the system gets locked up, even on completely unrelated drives that have no btrfs partition on them.
I'd try debugging when it happens again but I have absolutely no idea how to go about that on Windows. Since the system doesn't crash there's no dump - so how could I see what it's currently doing (or not doing for that matter)?
@maharmstone I've finally gotten around to familiarise myself with Windows Kernel Debugging and the results look promising (to me anyway).
As I said, the problem happens when Steam updates games, that's why you see steam.exe in the following dumps.
From what I understand it looks like a deadlock between fast_io_write and the flush-thread.
Looking at the commit history it seems like you beat me to it by 3 days 😃 So hopefully my findings here help confirm a potential suspicion you might have had there 🙂
