[Bug 14156] Running fsstress "fsx" on ext4 filesystem gives dirty metadata buffer warning message
http://bugzilla.kernel.org/show_bug.cgi?id=14156
--- Comment #1 from muni <[email protected]> 2009-09-16 12:03:48 --- While running the fsx tests on 2.6.31-rc8 kernel, the above mentioned occurred.
Steps for running fsx test:
1. Create an ext4 partition with blocksize 1024 and mount it with "-o errors=panic,data=journal" options
2. Install the autotest framework
3. Run fsx test attached to this bug
4. Check the dmesg.
You can see several messages like the one below:
kernel: JBD: Spotted dirty metadata buffer (dev = sdb5,
blocknr = 41444). There's a risk of filesystem corruption in case of system crash.
Thanks
