[workaround] NTFS parts randomly "drop out" of running system

I am experiencing issues with NTFS partitions seemingly randomly becoming inaccessible (relevant dmesg output at the bottom). I do not know what is triggering it. Already checked all partitions for errors in Windows 10.

After the "drop out" it is impossible to access anything on the affected partition(until reboot, then it just works again, though rebooting requires hard-reset because shutdown indefinitely waits for an unmount which never succeeds).

It is also impossible to unmount, neither regular unmount nor lazy unmount have an effect, remounting also fails. It happens to different partitions not always the same one and it also happens on both rotational disks and SSDs. It never affects my non-NTFS partitions though.

lsa -al shows an affected partition like this (C is affected here):

rwxrwxrwx 11 dennis dennis 4.0K 16. Mai 2019  .
drwxrwxrwx 18 dennis dennis 4.0K 25. Dez 11:26 ..
drwxrwxrwx  1 dennis dennis 8.0K  7. Feb 18:46 <redacted A>
drwxrwxrwx  1 dennis dennis  48K  7. Feb 18:46 <redacted B>
d?????????  ? ?      ?         ?             ? <redacted C>

mount options from fstab:

UUID=<redacted UA>	<redacted A>	ntfs-3g	uid=dennis,gid=dennis,rw,user,exec,umask=000,allow_other,big_writes 0 0
UUID=<redacted UB>	<redacted B>	ntfs-3g	uid=dennis,gid=dennis,rw,user,exec,umask=000,allow_other,big_writes 0 0
UUID=<redacted UC>	<redacted C>	ntfs-3g	uid=dennis,gid=dennis,rw,user,exec,umask=000,allow_other,big_writes 0 0

I also already tried with and without the "big_writes" mount option. It happens in both cases.

Where could I look for further info? Any ideas what could be causing this or how to fix it without rebooting?

relevant dmesg output:

Re: [workaround] NTFS parts randomly "drop out" of running system

Can you reproduce on the standard kernel? There have been some reports with issues with the CK patchset.

General Protection fault is often also memory related, so you should check your memory with memtest and maybe also ensure your microcodes are set up

Re: [workaround] NTFS parts randomly "drop out" of running system

Thank you for the suggestions. Microcode patches are already set up with early loading at boot. RAM is flawless. I have not tried the standard kernel yet, decided to work around the issue by converting my most frequently used partitions to ext4 now. Will test with the standard kernel and the remaining NTFS partitions later.

Re: [workaround] NTFS parts randomly "drop out" of running system

I've had the same problems with a shared (ntfs) harddrive. Mine was memory related on a Ryzen cpu (2700X). If I lowered my memory to 3200 and loosened the timings to 15-15-15-36 (from 3400, 15-15-15-34), I stopped having the ntfs drive drop out and the insanely long reboot times.

Re: [workaround] NTFS parts randomly "drop out" of running system

I had the same problem with NTFS drives on my Haswell system but since the motherboard died and moved to skylake-x haven't had a single problem with them.
it first started with the 5.4 kernel for me.

this was the report i made at the time. https://bugzilla.kernel.org/show_bug.cgi?id=205803
though i report it was fixed it did happen a few times after i replied, at least until the mobo died.

Re: [workaround] NTFS parts randomly "drop out" of running system

Thanks for the input everyone. My memory clock and timings already are at safe values 2133,15-15-15-36 and the problem persists (in CK kernel).

Left the machine running for 12h copying stuff around under the standard kernel now and so far all NTFS partitions are still up and alive, so I think it's safe to assume it's an issue with the CK patchset as V1del suggested.

So, I'm changing the thread-title and I'll ask in the CK support thread to have people have a look at this one. Meanwhile I'll continue to convert all my NTFS partitions to ext4.

Re: [workaround] NTFS parts randomly "drop out" of running system

I spoke too early, while I continued to copy stuff around, the problem occurred in the standard kernel as well.

dmesg output:

Re: [workaround] NTFS parts randomly "drop out" of running system

hmm, I don't use big_writes maybe a regression there?

Re: [workaround] NTFS parts randomly "drop out" of running system

I had enabled big_writes only to see if it made a difference. It happens with and without big_writes for me.

Re: [workaround] NTFS parts randomly "drop out" of running system

Could not find anymore information on this so I ended up converting all of my NTFS partitions to ext4 as a workaround (except for the Windows system partition and for accessing the ext4 partitions under Windows I'm using a proprietary driver from Paragon).

Re: [workaround] NTFS parts randomly "drop out" of running system

After the "drop out" it is impossible to access anything on the affected partition(until reboot, then it just works again, though rebooting requires hard-reset because shutdown indefinitely waits for an unmount which never succeeds).

I have been getting this same behavior, on occassion - the partition becomes inaccessible, and I have to forcefully reboot the system for it to work again.

I have been experiencing issues with my NTFS partition for some times, but today I reproduced issue (one of the issues?) as soon as my system booted up. Here is what I consider to be the relevant information:

In the event that more output than this is needed, I have the whole journald output for that boot saved. I won't link the whole thing out of privacy concerns, but I will add the first couple of lines with kernel + command line info:

As far as I understand this, FUSE is crashing, preventing the partition from being mounted properly. Should a bug report be filed?

Re: [workaround] NTFS parts randomly "drop out" of running system

@CodingKoopa can you reproduce the issue on an untainted unpatched kernel?

Re: [workaround] NTFS parts randomly "drop out" of running system

That may be difficult to do because of my proprietary graphics drivers. If I can reproduce it on an untainted vanilla Arch kernel, I'll share here.

EDIT: Due to constant crashing with Nouveau, being unable to reproduce the issue, and another crash (the Nvidia one I pasted above), I likely won't be able to get untainted info so any time soon, unfortunately.
