Now I force an unmount in the shutdown script. I remember that when fuse module was still in fusefs-kmod, the rc script unmounts the file systems, and there's even a _safe flag to ensure safety. -- > Kevin Oberman, Network Engineer, Retired > E-mail: rkober...@gmail.com > ___ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org" ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"

The fuse daemon shuts down before any fusefs based file systems are unmounted, but, for several R/W file systems including NTFS and exFAT, the result is a corrupt file system. I did the same thing to work around this problem... an init script, but I wonder if this should not be handled in some cleaner and more global manner.

So, is this correct or have I done something stupid? I believe that is correct. hans changed how they are declared with r267961 and now you do not need TUNABLE_INT() on -head. And, if it correct, do I commit a patch like the above directly to stable/10. (It seems that TUNABLE_INT() is discouraged for -head.) That's the correct way, afaik. Cheers, Hiren Is there a reason the sysctl tunable flag changes can't be MFC'd? Leaving changes that widespread un-mfc'd just makes for lots of merge conflicts as time goes on (and can also lead to merged code behaving differently than expected). Added Hans to answer the question. Hi, I wasn't sure if MFC'ing would break anything with regard to binary compatibility, so the change was kept in -head and only the broken SYSCTLs were fixed in 10- and 9- . --HPS ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"

Re: Pluggable frame buffer devices
Hello I have an AOC e2251fwu monitor which I have used under debian using libdlo with success in the past. I have used the same driver under OpenBSD for testing purpose only with "make check" and it's rendering the test on the attached monitor. I have spend one week and trying to figure out how to make the monitor work under FreeBSD. I have recompile the kernel using you're support for the udl.c and loaded the module in the kernel. kldstat: Id Refs AddressSize Name 41 0x81fd6000 9e20 udl.ko 52 0x81fe 71b0 videomode.ko I have installed the xf86-video-scfb from the ports. And I'm stuck, can't figure out why in the dmsg the adapter is still recognize as a generic usb device shouldn't the drivers kicked in at this point making the monitor available as a framebuffer adapter in /dev ? dmsg | grep DisplayLink ugen2.3: at usbus2 Can you please provide some instructions regarding the steps involved in making this monitor work? Thank you. -- View this message in context: http://freebsd.1045724.n5.nabble.com/Pluggable-frame-buffer-devices-tp5989022p6017846.html Sent from the freebsd-current mailing list archive at Nabble.com. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"

The slow shutdown is caused by some remote smbfs shares mounted via openvpn: the remote drives are unmounted after the openvpn daemon termination, this induces some long timeout. The solution is to unmount the smbfs shares in a shutdown script before the openvpn daemon termination. I have discovered this issue with this ‘dirty’ patch that displays the unmounted fs at shutdown: http://pastebin.com/Xfiz9nsv With this patch shutting down my laptop appear as: https://drive.google.com/file/d/0BzoWQoMqq1sfcHZyRnlEeTRobFU/view?usp=sharing . For testing the the patch apply it in /sys/kern, rebuild and install the kernel. Set the new OID: # sysctl kern.shutdown.show_umountfs=1 Halt the system: # shutdown -h now Regards, Maurizio ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
