I have patch ready to change unhelpful on OpenIndiana, SmartOS and other illumos distributions mention of modprobe to suggest:
/usr/sbin/add_drv -m 'fuse 0666 root sys' fuse
Still have to find out, why the heck link was not created in the first place. :/
I recently had to use ntfs formatted USB drive under OpenIndiana and run into a small problem.
I shamelessly used gparted to find which device maps to my usb disk. Then had following session with ntfs-3g binary:
ntfs-3g /dev/dsk/c2t0d0p1 /mnt/
The disk contains an unclean file system (0, 0).
The file system wasn't safely closed on Windows. Fixing.
fuse: device not found, try 'modprobe fuse' first
Both fuse and ntfs-3g are installed from repositories:
sfe origin online http://pkg.openindiana.org/sfe/
sfe-encumbered origin online http://pkg.openindiana.org/sfe-encumbered/
After some digging around and asking on IRC I decided that either no one had this problem or no one bothered to post solution. modinfo showed me that fuse module is loaded, after all:
258 fffffffff7edd000 e680 290 1 fuse (fuse driver)
258 fffffffff7edd000 e680 28 1 fuse (filesystem for fuse)
However ntfs-3g itself didn't say anything useful. It also suggested to use modproble, which is just ridiculous on OpenIndiana. I decided to truss it.
open64("/dev/fuse", O_RDWR) Err#2 ENOENT
One clue closed I downloaded spec file for fuse from http://pkgbuild.sourceforge.net/spec-files-extra/ and checked for %post step:
/usr/sbin/add_drv -m 'fuse 0666 root sys' fuse || retval=1;
[ "$retval" = 0 ] && ln -s /devices/pseudo/fuse@0:fuse /dev/fuse || retval=1;
I did check if /devices/pseudo/fuse exists (it did) and then created /dev/fuse link to it. Then ntfs-3g worked like a charm.
