Date: Tue, 28 Sep 2010 01:56:26 GMT [thread overview]
Message-ID: <bug-19212-13602@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=19212
Summary: kernel BUG at
/build/buildd/linux-2.6.32/fs/ext4/extents.c:1716
Product: File System
Version: 2.5
Kernel Version: 2.6.32
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: ext4
AssignedTo: fs_ext4@kernel-bugs.osdl.org
ReportedBy: kernel_sm@ChinaNetCloud.com
Regression: No
Just started hitting this error quite often - server has been fine for months
but now we get these after every reboot, sometimes within a minute or two, or
after a few hours. Leaves processes in zombie or D/D+ state so have to reboot.
fsck on file system is all clean, but get errors on forced (see below)
On Ubuntu Server - their kernel 2.6.32-24-server
Heavy I/O load with 24 disks on JBOD controller, which is Adaptec 5405, no
RAID, no LVM, no DM - handling 200-300MB/sec across 24 disks, so pretty heavily
loaded. Running irq balance. 16 core machine with 48GB RAM, 50% for FS cache.
Kernel log all the same:
