Public bug reported: I use heavily encfs and sshfs filesystems. Since 12.10 I observe regularly that mounted filesystems go awry but remain mounted, and files within them are not accessible. The obvious symptom is listing the folder in which they're mounted. In the following example an encfs is mounted in a folder named 'dropbox':
$ ls -lF ls: cannot access dropbox: Transport endpoint is not connected total 16K d????????? ? ? ? ? ? dropbox/ -rwxr-xr-x 1 jano jano 937 mar 6 10:39 fixlinks* There is the dropbox folder and the the regular file fixlinks, for comparison, which is in the same folder. Sometimes the folder can be unmounted simply with sudo umount <folder>, others it is necessary to use -l (lazy unmount). I suspected encfs could be responsible, until I saw this with a sshfs filesystem. Still, I've been able to locate any log or crash message to confirm that fuse is the culprit. Any indications on how to debug this further are welcome. This tends to happen once a day, but it seems that heavy access (e.g., doing a find in the root of the fs) tends to favor its occurrence. I'm sorry if this has been already reported but searching for 'd?????????' seems futile in google. $ lsb_release -rd Description: Ubuntu 12.10 Release: 12.10 $ apt-cache policy fuse fuse: Installed: 2.9.0-1ubuntu2 ** Affects: fuse (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1152186 Title: possible fuse crash and inaccessible mounted filesystem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fuse/+bug/1152186/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
