Subject: [Bug 14452] New: Syscall to ftruncate hangs on ext4 + mdadm raid0
filesystem on a file preallocated with fallocate
http://bugzilla.kernel.org/show_bug.cgi?id=14452
Summary: Syscall to ftruncate hangs on ext4 + mdadm raid0
filesystem on a file preallocated with fallocate
Product: File System
Version: 2.5
Kernel Version: 2.6.31.1
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: blocking
Priority: P1
Component: ext4
AssignedTo: fs_ext4@...nel-bugs.osdl.org
ReportedBy: nablamanspamtrap@...il.com
Regression: No
My program creates a big file (around 30 GB) with posix_fallocate (to utilize
extents), fills it with data and uses ftruncate to crop it to its final size
(usually somewhere between 20 and 25 GB). The problem is that in around 5% of
the cases, the program locks up completely in a syscall. The process can thus
not be killed even with kill -9, and a reboot is all that will do.
Here is the contents of my /proc/PID/syscall:
76 0xee4a80 0x486d6aaf8 0x36390113f8 0x7fffc63cd350 0xecc050
0x7fffc63cd3f0 0x7fffc63cd5c8 0x36380e0cc7
Syscall 76 is as far as I can tell getrlimit, which I do not call. It
must have been called somewhere from ftruncate.
The file is on a software raid 0 mount with two disks, handled by
mdadm. I have reported the problem to the md people but they insist
it's an ext4 problem.
I have also tried closing the file and opening it again prior to the
ftruncate. No change.
There are no other strange phenomena whatsoever with ext4. This
problem only arises in this particular situation.
I'm running Fedora on an x86_64 system.
I have tried this on several kernel versions, the last one 2.6.31.1.
It has persisted all the way since the 2.6.29 kernel that originally shipped
with Fedora 11.
Following is all data generated by sysrq + w (hung processes).
Drdbmake, receptd and nodeserv are my own processes.
