 version 2013.1.13 mount fails on gentoo Hi, I recall that this used to work on my machine a while ago, but after many updates ntfs-3g seems to have stopped working. I tried debugging it but the behavior is strange: it mounts the drive and then unmounts it. Here's my fstab entry: Code: /dev/mapper/nvidia_ceebaiib2 /mnt/tv ntfs-3g defaults,debug,noauto 0 2
When I do 'mount /mnt/tv', there is no error in dmesg. Here's what I see on journalctl -r: Code: Jan 08 22:55:56 *** systemd[1]: Unmounted /mnt/tv.
Jan 08 22:55:56 *** systemd[1]: Unmounting /mnt/tv...
Jan 08 22:55:56 *** systemd[1]: Unit mnt-tv.mount is bound to inactive service. Stopping, too.
The actual debug output from the mount command is attached. This is not specific to this partition, as another partion also fails to mount. My system is: Code: # uname -a
Linux antec 3.13.4-gentoo #1 SMP PREEMPT Sun May 11 12:36:34 EDT 2014 x86_64 Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz GenuineIntel GNU/Linux

Re: version 2013.1.13 mount fails on gentoo Hi, From your debug data : Code: INIT: 7.22
flags=0x0000f7fb
max_readahead=0x00020000
INIT: 7.19
flags=0x00000051
max_readahead=0x00020000
max_write=0x00020000
max_background=0
congestion_threshold=0 There appears to be some incompatibility of versions between the fuse kernel and the fuse library which show protocol versions 7.22 (kernel) and 7.19 (library, older). First check for an update of the fuse library. If you do not have an upgrade at hand, best to recompile ntfs-3g from source and use its own version of the fuse library, which will negotiate a protocol version 7.12. Just remove "--with-fuse=external" from your ./configure options. Note : this could be a consequence of a bug recently found in fuse being initialized before the protocol version is negotiated : see http://article.gmane.org/gmane.comp.fil ... evel/14525Regards Jean-Pierre

Re: version 2013.1.13 mount fails on gentoo Jean-Pierre: Thanks for the quick reply! I see now that those two version numbers are mismatching. My Gentoo was stuck between upgrades, and I guess it's showing here. Although I don't understand how SSHFS is working. Is NTFS-3G stopping as a sanity check? Maybe it should give out a more verbose error if that's the case. I tried compiling without external-fuse, but this time I got an even bigger version mismatch: Code: # mount -t ntfs-3g -o debug /dev/mapper/nvidia_ceebaiib2 /mnt/tv

Re: version 2013.1.13 mount fails on gentoo I also recompiled fuse to no avail. Here's my fuse kernel module: Code: # modinfo /lib/modules/3.13.4-gentoo/kernel/fs/fuse/fuse.ko
filename: /lib/modules/3.13.4-gentoo/kernel/fs/fuse/fuse.ko
alias: devname:fuse
alias: char-major-10-229
alias: fs-fuseblk
alias: fs-fuse
license: GPL
description: Filesystem in Userspace
author: Miklos Szeredi <miklos@szeredi.hu>
alias: fs-fusectl
depends:
intree: Y
vermagic: 3.13.4-gentoo SMP preempt mod_unload
parm: max_user_bgreq:Global limit for the maximum number of backgrounded requests an unprivileged user can set (uint)
parm: max_user_congthresh:Global limit for the maximum congestion threshold an unprivileged user can set (uint) Not sure what API version does this one have. I'm still confused what is the source of the incompatibility.

Re: version 2013.1.13 mount fails on gentoo Hi again, Quote: I see now that those two version numbers are mismatching. My Gentoo was stuck between upgrades, and I guess it's showing here. The version mismatch is not wrong. The kernel part of fuse and the library part negotiate an agreement on a protocol version they both support. But in your situation the kernel part gives up immediately after the negotiation. Quote: Is NTFS-3G stopping as a sanity check? Maybe it should give out a more verbose error if that's the case. Actually, it is the fuse kernel which is stopping, and this happens before any communication with ntfs-3g has taken place. Quote: I tried compiling without external-fuse, but this time I got an even bigger version mismatch: This is correct, the internal fuse library traditionally negotiates protocol 7.12 with the kernel. However the fuse kernel also gives up immediately. The version 2014.2.15AR.3 of ntfs-3g (and only this version) would negotiate protocol 7.18, you might give it a try, see http://www.tuxera.com/community/ntfs-3g ... /#download However, as the behavior is the same with the internal and the internal fuse library, the problem most likely lies in the fuse kernel, and you probably need to switch to another kernel version (or reinstall the same one, as you mentioned your latest install behaved oddly). Regards Jean-Pierre

Re: version 2013.1.13 mount fails on gentoo Ok, then it sounds like I need to try different kernels, or as you said, rebuild the current one.
FYI I am at the latest fuse library version 2.9.3.
And regarding the bug report you previously linked, it was reported from a much newer kernel than mine (3.13.4). So maybe indeed I am behind.

Since you said there is a problem with the kernel fuse and userspace librarsy negotiation, I went back to older kernels I have had installed. Both 3.11 and 3.10 had FUSE protocol 7.22, which still didn't work. Kernel 3.2 gave a different error: fuse operation not permitted. I assume that was simply too old. Do you think downloading and compiling from the link you gave would make a difference? Any other suggestions? Thanks, Cengiz

Re: version 2013.1.13 mount fails on gentoo Nevermind! I found the problem.  It would not mount to /mnt/tv, but it will to /mnt/tmp. I have no clue why. I deleted the entry with tv from fstab, but it still happens. I opened another directory with two letters ("aa") and that works too. The only one that consistently fails is "tv". It has the same permission as the other /mnt directories. Deleting and re-creating didn't change anything. Here's the debug output for the mount: Code: # mount -t ntfs-3g -o debug /dev/mapper/nvidia_ceebaiib2 /mnt/tv2

Anyway, thanks for helping. I assume there is nothing to learn from this? Best, Cengiz

Re: version 2013.1.13 mount fails on gentoo Hi, Quote: I'm not sure this is AR.3 since it's still showing protocol 7.19 in the debug output (with external FUSE): It is a reliable version, but it is not AR.3. The protocol negotiation is done by the fuse library, and when you use the external one, it is unrelated to ntfs-3g. Quote: Nevermind! I found the problem. Good news ! Quote: It would not mount to /mnt/tv, but it will to /mnt/tmp. Glad you reported it. I never saw such a thing. Quote: I assume there is nothing to learn from this? Yes, there is : mind the mount point ! Regards Jean-Pierre

Re: version 2013.1.13 mount fails on gentoo jpa wrote: Quote: I assume there is nothing to learn from this? Yes, there is : mind the mount point !  Actually I went further and figured out that the reason is systemd. I was composing a reply yesterday, but apparently I forgot to submit. The hint was the first thing I submitted in the OP: Code: # journalctl -r
Jan 08 22:55:56 *** systemd[1]: Unmounted /mnt/tv.
Jan 08 22:55:56 *** systemd[1]: Unmounting /mnt/tv...
Jan 08 22:55:56 *** systemd[1]: Unit mnt-tv.mount is bound to inactive service. Stopping, too. Even though I changed fstab, the rules systemd *generated* at boot time were still active. So it thought it was an "inactive" service.  These were mount points that depended on a Nvidia fake-raid disk (/dev/mapper/nvidia_ceebaiib2) that are not automatically supported by systemd. So the saga continues for me, but I'll probably take it off your plate  Thanks again..
