[Bug 471249] New: mount hangs trying to loopback an image on a fuse mouted NTFS partition
https://bugzilla.novell.com/show_bug.cgi?id=471249 Summary: mount hangs trying to loopback an image on a fuse mouted NTFS partition Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: x86-64 OS/Version: openSUSE 11.1 Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: contact@philipashmore.com QAContact: qa@suse.de Found By: --- User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.9.0.5) Gecko/2008121300 SUSE/3.0.5-1.1 Firefox/3.0.5 In Vista I reduced the two NTFS partitons to their minimum to make space for a GNU/Linux install. Now I can dual boot OpenSuse and Vista. As it turned out, Vista still has over 20GB of free space, so I created a 15GB file using a small C++ program that calls truncate() on the specified file. I could be wrong but I think that by calling truncate, I'm creating a sparse file. It's thousands of times faster than "dd if=/dev/zero ..." which I think also creates a sparse file. # touch /windows/C/Users/me/Desktop/Linux/15G.img # truncate /windows/C/Users/me/Desktop/Linux/15G.img 15G # mkfs -t ext2 /windows/C/Users/me/Desktop/Linux/15G.img Finally I mounted the filesystem using a loopback device. # mount -o,loop,exec /windows/C/Users/me/Desktop/Linux/15G.img /home/butthaed/WinPart I've used this loopback partition intensively and it works fine. Recently, however, I'm getting a kerneloops... http://www.kerneloops.org/submitresult.php?number=205350 ..and the mount never completes. Shutdown also doesn't complete (5 seconds on the power off button solves this) and I get the "recovering journal" and "orphaned inodes" when the machine boots up. Reproducible: Always Steps to Reproduce: 1. Install OpenSuse on a Vista machine dual boot. 2. Create a block file on an NTFS partition. 3. Create an ext2 filesystem on the block file. 4. Mount it and use it. Actual Results: Worked great for a while. Now it kerneloops'es. Expected Results: No kerneloops'es. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

(that one above) i`d try upgrading to the latest ntfs-3g first and if that doesn`t help, also upgrade to latest fuse. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

i`d try upgrading to the latest ntfs-3g first The only version available is the one on the DVD - ntfs-3g-1.5012-2.15 and if that doesn`t help, also upgrade to latest fuse. The only version available is the one on the DVD - fuse-2.7.2-61.16

The graphics performance is a LOT better (must be the intel driver) :) Unfortunately I've still got the mount-hang problem.

It refused to mount the block device saying that it basically couldn't identify it. so I ran... # e2fsck -f <block file on ntfs partition> ..and I can mount this loopback from Fedora 10 just fine, although I did notice that F10 is using a later kernel. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

cat loop-barriers |head -n 15 From: Jeff Mahoney <jeffm@suse.com> Subject: [PATCH] loop: add support for O_SYNC References: 189051 Patch-mainline: never - this is a temporary band-aid for SLES10 This patch adds support for O_SYNC to the block loop device. When the backing file is opened with O_SYNC, the loop device will sync writes before returning successful. Signed-off-by: Jeff Mahoney <jeffm@suse.com> cat loop-barriers2 |head -n 15 From: kraxel@suse.de Subject: Make the loop driver handle barrier requests. Patch-mainline: no Make the loop driver handle sync and barrier requests correctly. Depends on loop-barrier patch.
It hasn't been pushed to mainline, which is a sign that it isn't so important.
oh,i think there is MUCH important kernel stuff around which is NOT in mainline. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Unfortunately I'm still stuck for another reason... This machine not only uses FUSE but also runs Asterisk (PBX software), which in turn requires a kernel module (dahdi-linux-kmp-trace) built in the network:telephony:asterisk OBS project. This kernel module is built against the standard openSUSE 11.1 kernel (currently 2.6.27.19-3.2.1), not the SL111_BRANCH version. So is this patch going to be merged into the standard openSUSE 11.1 kernel (and thus appear in the 11.1-updates repo), so that I can use it on my Asterisk box?
