https://bugzilla.novell.com/show_bug.cgi?id=741472 https://bugzilla.novell.com/show_bug.cgi?id=741472#c0 Summary: Won't mount root during boot. kernel BUG at /home/abuild/rpmbuild/BUILD/kernel-default-3.1.0/linux -3.1/fs/btrfs/volumes.c:2891! Classification: openSUSE Product: openSUSE 12.1 Version: Final Platform: x86-64 OS/Version: SuSE Other Status: NEW Severity: Normal Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: steve@bradfield.org QAContact: qa@suse.de Found By: --- Blocker: --- Created an attachment (id=471281) --> (http://bugzilla.novell.com/attachment.cgi?id=471281) Log output from attempting to map from rescue dvd User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:9.0.1) Gecko/20100101 Firefox/9.0.1 This morning, my pc was fine. I modified a spreadsheet and saved. About 15 minutes later, I came back to wake it from screensaver and it would not respond at all. After several minutes, I restarted the system and now it will not load the /root partition. I booted from the rescue cd and tried to run fsck on the partitions, but nothing is reported. I tried mounting various partitions and all were successful with the exception of my root partition. When I try to mount that, it gives me a message "invalid opcode: 0000 [#1] SMP" and about 4 lines after that, but the mount fails. If I try again, the command line becomes unresponsive and I cannot break out. I was able to resolve the issue using the btrfs utility "btrfs-zero-log" Reproducible: Always Steps to Reproduce: 1. Reboot system 2. Initialization fails when it cannot load root file system 3. Repeat Alternatively, trying to map the partition from the rescue DVD produces same issue Actual Results: When I try to mount that, it gives me a message "invalid opcode: 0000 [#1] SMP" and about 4 lines after that, but the mount fails. If I try again, the command line becomes unresponsive and I cannot break out. Expected Results: Proper boot, mount root and load KDE Jan 13 18:35:33 Rescue kernel: [ 104.657253] ------------[ cut here ]------------ Jan 13 18:35:33 Rescue kernel: [ 104.657299] WARNING: at /home/abuild/rpmbuild/BUILD/kernel-default-3.1.0/linux-3.1/fs/btrfs/tree-log.c:1729 walk_down_log_tree+0x15a/0x3e0 [btrfs]() Jan 13 18:35:33 Rescue kernel: [ 104.657307] Hardware name: System Product Name Jan 13 18:35:33 Rescue kernel: [ 104.657311] Modules linked in: btrfs zlib_deflate nls_utf8 ppa arc4 ecb powernow_k8 mperf fan thermal nfs nfs_acl lockd fscache auth_rpcgss sunrpc nls_iso8859_1 nls_cp437 af_packet st usbhid usb_storage uas radeon ata_generic parport_pc ohci_hcd parport ttm drm_kms_helper button drm ehci_hcd wmi pata_atiixp xhci_hcd i2c_algo_bit ssb mmc_core usbcore sr_mod cdrom pcmcia pcmcia_core sg processor r8169 thermal_sys edd squashfs loop Jan 13 18:35:33 Rescue kernel: [ 104.657389] Pid: 2751, comm: mount Not tainted 3.1.0-1.2-default #1 Jan 13 18:35:33 Rescue kernel: [ 104.657394] Call Trace: Jan 13 18:35:33 Rescue kernel: [ 104.657421] [<ffffffff810042fa>] dump_trace+0x9a/0x270 Jan 13 18:35:33 Rescue kernel: [ 104.657435] [<ffffffff81523edb>] dump_stack+0x69/0x6f Jan 13 18:35:33 Rescue kernel: [ 104.657449] [<ffffffff81051eab>] warn_slowpath_common+0x7b/0xc0 Jan 13 18:35:33 Rescue kernel: [ 104.657485] [<ffffffffa04709aa>] walk_down_log_tree+0x15a/0x3e0 [btrfs] Jan 13 18:35:33 Rescue kernel: [ 104.657742] [<ffffffffa0470f57>] walk_log_tree+0xc7/0x1f0 [btrfs] Jan 13 18:35:33 Rescue kernel: [ 104.657990] [<ffffffffa0474d2c>] btrfs_recover_log_trees+0x1ec/0x2d0 [btrfs] Jan 13 18:35:33 Rescue kernel: [ 104.658244] [<ffffffffa0441c63>] open_ctree+0x13c3/0x1740 [btrfs] Jan 13 18:35:33 Rescue kernel: [ 104.658357] [<ffffffffa04206d3>] btrfs_fill_super.isra.36+0x73/0x150 [btrfs] Jan 13 18:35:33 Rescue kernel: [ 104.658395] [<ffffffffa0421ac9>] btrfs_mount+0x359/0x3e0 [btrfs] Jan 13 18:35:33 Rescue kernel: [ 104.658424] [<ffffffff8114e185>] mount_fs+0x45/0x1d0 Jan 13 18:35:33 Rescue kernel: [ 104.658437] [<ffffffff81166736>] vfs_kern_mount+0x66/0xd0 Jan 13 18:35:33 Rescue kernel: [ 104.658448] [<ffffffff81167ac3>] do_kern_mount+0x53/0x120 Jan 13 18:35:33 Rescue kernel: [ 104.658458] [<ffffffff81169575>] do_mount+0x1a5/0x260 Jan 13 18:35:33 Rescue kernel: [ 104.658470] [<ffffffff81169a1a>] sys_mount+0x9a/0xf0 Jan 13 18:35:33 Rescue kernel: [ 104.658481] [<ffffffff81543e12>] system_call_fastpath+0x16/0x1b Jan 13 18:35:33 Rescue kernel: [ 104.658495] [<00007f5e188f4daa>] 0x7f5e188f4da9 Jan 13 18:35:33 Rescue kernel: [ 104.658500] ---[ end trace b339d3701a74932f ]--- Jan 13 18:35:33 Rescue kernel: [ 104.658531] unable to find logical 20890721841152 len 4096 Jan 13 18:35:33 Rescue kernel: [ 104.658558] ------------[ cut here ]------------ Jan 13 18:35:33 Rescue kernel: [ 104.658567] kernel BUG at /home/abuild/rpmbuild/BUILD/kernel-default-3.1.0/linux-3.1/fs/btrfs/volumes.c:2891!

Does it happen with 3.2 kernel as well?
warning fs/btrfs/tree-log.c:1729 suggests that there is a severe corruption on the disk (data read from disk do not contain expected value).
Kernel 3.2 contains some important fixes wrt corrupted fs after power outage or kernel crash. It can be found in buildservice project Kernel:stable.
I don't know. I was running 3.1 when it occurred. I fixed the problem by running the "btrfs-zero-log" utility, so it is no longer occurring. Since the utility fixed the problem, I do not believe the disk was corrupted. I have since removed btrfs from my root file system. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Well, it was in the area the utility zeroed out. Closing. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
