https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=210316 Damjan Jovanovic <damjan.jov@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |damjan.jov@gmail.com --- Comment #5 from Damjan Jovanovic <damjan.jov@gmail.com> --- Still a problem on CURRENT. Very easy to reproduce: dd if=/dev/zero of=/path/to/image bs=1M count=100 newfs_msdos /path/to/image ggatel create -o ro /path/to/image mount /dev/ggate0 /mnt A few seconds later: crash. I wonder what the best way to fix this is. Should the referenced geom explicitly be cleared from the buffer after the failed write? Should the msdosfs driver call fsync() before g_vfs_destroy()-ing the geom on mount failure, so the dirty buffer is deleted before the geom device it references is deleted? Should geom devices be reference counted by their buffers and be forced to live until all buffers that reference them are deleted? -- You are receiving this mail because: You are the assignee for the bug.home | help
