Fixed In Version: kernel-2.6.32-71.4.1.el6
Doc Type: Bug Fix
Doc Text:
Running a fsstress test which issues various operations on a ext4 filesystem when usrquota is enabled, the following JBD (Journaling Block Device) error was output in /var/log/messages: JBD: Spotted dirty metadata buffer (dev = sda10, blocknr = 17635). There's a risk of filesystem corruption in case of system crash. With this update, by always journaling the quota file modification in an ext4 file system the aforementioned message no longer appears in the logs.
