OpenBSD NTFS experience

[Ed Gray]

Hi,

Has anyone had experience using NTFS with OpenBSD and if so any
pointers particularly around performance and any problems encountered?

I realise NTFS is probably not used by many people but I have an
external drive which is formatted with it.

It would be useful to know if anyone is using the read-only NTFS
driver or ntfs-3g port successfully and if there are any known bugs
with these.

Thanks for your reply Maurice,

I tried the read-only driver on an earlier version maybe 6.6 and it
crashed. I wasn't able to debug it myself but I suppose it could have been
my external hard drive, the NTFS version or a particular file that caused
that issue as it happened with a large data copy and a particularly large
file (multiple GB).

I'm finding poor performance with USB drives on 6.8 with a hard disk and a
card reader. It could be ntfs-3g with the hard drive but the card is FAT32.
I am wondering if it's to do with the default shm kernel variables or
maxfiles and such. It causes various hangs in thunar file manager.

I previously had increased shm variables because of a KDE application
recommending it for lots of file accesses.

I know ntfs-3g is using FUSE rather than a native driver.

My latest issue with NTFS was that my external drive stopped
responding and caused Thunar to hang. After this my entire session
hung until I killed it with Ctrl + Alt+ backspace.

It seems the rsync data copy I did completely properly but the mount
stopped responding after some time of the PC being unused. Any
attempts to access the mounted directory caused a hang of the terminal
or process.

I  can now see with atactl that my USB hard drive supports power
management and looks to be in standby mode when not in use. I am
wondering if maybe the drive goes into standby or powers down and that
causes the mount to stop working or if it is a bug in NTFS-3G support
or something else.

This time I am going to run ntfs-3g with the debug mode enabled in
no_detach to determine if there are any errors when the drive is left
connected but unused.

It outputs the following on successful mount:

Version 2017.3.23 external FUSE 26
Mounted /dev/sd2i (Read-Write, label "SAMSUNG", NTFS 3.1)
Cmdline options: no_detach
Mount options: allow_other,nonempty,relatime,fsname=/dev/sd2i,blkdev,blksize=4096
Ownership and permissions disabled, configuration type 1

I am still having issues with NTFS-3G and an external Samsung M3 USB
HDD. I am able to mount and access the filesystem fine for several
hours, then without doing anything or having any crashes or errors the
mount becomes inaccessible.

The disk still responds to the disklabel -E command and smartctl
commands so I assume it is working properly and not asleep.

There is no debug output from ntfs-3g when this happens apart from the
initial messages in my previous e-mail. However there are some entries
after I disconnect the drive.

There are no errors in syslog, dmesg or anywhere else that I can see.

Thunar stops working but leaves a process behind. I cannot remount the
filesystem read-only. Any processes that try to access the mount are
in state 'idle' and waiting for 'fuseino'. I cannot kill any of these
processes.

If I disconnect the drive without rebooting and leave the system alone
again overnight the commands that hang (ls, mount, Thunar) respond
again and complete and I can finally kill the ntfs-3g process.

My dmesg is:
