Description Mads Kiilerich 2012-04-16 14:45:07 UTC

grub2-mkconfig hangs - because os-prober hangs.


Some mount.ntfs processes were hanging. After killing them hardly I can do:

[root@dev-mk ~]# mount /dev/sda2 /mnt
The disk contains an unclean file system (0, 0).
The file system wasn't safely closed on Windows. Fixing.

- and it will hang.


I would expect os-prober to do probing in such a way that external failing or hanging tools didn't stop the probing ... and if other tools are considered essential then it should show the output from them so debugging was possible.


os-prober-1.51-1.fc17.i686
fuse-2.8.6-4.fc17.i686
ntfs-3g-2012.1.15-1.fc17.i686
kernel-PAE-3.3.0-8.fc17.i686 or kernel-PAE-3.3.1-5.fc17.i686

Comment 1 Hedayat Vatankhah 2012-04-16 15:10:31 UTC

IMHO it is too unrealistic to expect os-prober to be prepared that "every external program might hang"! Maybe mount.ntfs is really not expected to hang and a bug against it instead?

Another thing which comes to my mind is to mount partitions read only. It might prevent mount.ntfs from trying to fix the problem completely as I can see in its man page. If your partition is still unclean, can you try mount with -o ro option to see if it doesn't hang?

Comment 2 Pytela, Zdenek 2012-04-17 13:52:31 UTC

I can confirm this behaviour, similar situation but
fuse-2.8.7-1.fc17.x86_64
kernel-3.3.2-1.fc17.x86_64

Partition was unmounted cleanly, but now it cannot be mounted even read only:
mount.ntfs -o ro /dev/sda1 /mnt
hangs (10+ minutes) in fuse_get_req.

In f16 os-prober and mount work as expected.

Comment 3 Hedayat Vatankhah 2012-04-17 18:50:42 UTC

I really think that this bug should be assigned to ntfs-3g or fuse rather than os-prober.
