There's a risk of filesystem corruption in case of system crash. Product: File System Version: 2.5 Kernel Version: 3.0.0-rc7 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext4 AssignedTo: fs_ext4@kernel-bugs.osdl.org ReportedBy: baryluk@smp.if.uj.edu.pl Regression: Yes I was just updating some packages in 32-bit Debian unstable, under highload on my Thinkpad T43 (uniprocessor pentium-m). And spoted this thing in log: [79324.133130] JBD: Spotted dirty metadata buffer (dev = dm-2, blocknr = 2512725). There's a risk of filesystem corruption in case of system crash. dm-2 is block device (on LVM on luksCrypt) with /usr on ext4, with journal=data. I never ever seen such thing. # cat /proc/mounts | grep -v fuse rootfs / rootfs rw 0 0 sysfs /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0 proc /proc proc rw,nosuid,nodev,noexec,relatime 0 0 udev /dev devtmpfs rw,relatime,size=1031676k,nr_inodes=220204,mode=755 0 0 devpts /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0 tmpfs /run tmpfs rw,nosuid,noexec,relatime,size=207032k,mode=755 0 0 /dev/mapper/sredniczarny-root / ext4 rw,relatime,user_xattr,acl,barrier=1,nodelalloc,data=journal 0 0 tmpfs /lib/init/rw tmpfs rw,nosuid,relatime,size=5120k,mode=755 0 0 tmpfs /run/lock tmpfs rw,nosuid,nodev,noexec,relatime,size=5120k 0 0 tmpfs /run/shm tmpfs rw,nosuid,nodev,relatime,size=414060k 0 0 /dev/sda1 /boot ext3 rw,relatime,errors=continue,commit=5,barrier=1,data=ordered 0 0 /dev/mapper/sredniczarny-tmp /tmp ext4 rw,relatime,user_xattr,acl,barrier=1,data=ordered 0 0 /dev/mapper/sredniczarny-usr /usr ext4 rw,relatime,user_xattr,acl,barrier=1,nodelalloc,data=journal 0 0 /dev/mapper/sredniczarny-var /var ext4 rw,relatime,user_xattr,acl,barrier=1,nodelalloc,data=journal 0 0 /dev/mapper/sredniczarny-home /home ext4 rw,relatime,user_xattr,acl,barrier=1,nodelalloc,data=journal 0 0 rpc_pipefs /var/lib/nfs/rpc_pipefs rpc_pipefs rw,relatime 0 0 fusectl /sys/fs/fuse/connections fusectl rw,relatime 0 0 sctank2 /sctank2 fuse rw,relatime,user_id=0,group_id=0,allow_other 0 0 binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw,nosuid,nodev,noexec,relatime 0 0 nfsd /proc/fs/nfsd nfsd rw,relatime 0 0 /home/baryluk/.Private /home/baryluk/Private ecryptfs rw,relatime,ecryptfs_fnek_sig=caxxxxxx,ecryptfs_sig=e47xxxxx,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_unlink_sigs 0 0 /dev/sr0 /media/cdrom0 iso9660 ro,nosuid,nodev,noexec,relatime 0 0 # Kenrel config attached. I found two separate bug in Red Hat bugzilla which are similar, and occurs when usrquota is used, and some quota releated configuration is changed. I have hovewer no quota here (it is just laptop) enabled, configured, or even supported by my custom kernel. Any ideas? exact kernel version 3.0.0-rc7-t43-prod-00159-ge6625fa-dirty (dirty only because -march=pentium-m added to the build). gcc 4.6.1-4 used. 32bit i386. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
