Hello!
I tried to "cp --reflink" a huge file (about 80G, a VMware disk
image). It took maybe about 1 minute when my PC started thrashing the
hard disk, some minutes later the command returned with an out of
memory message. I could no longer open terminals in my KDE Konsole to
investiage dmesg. I could not start new programs. I could not log out.
Hard disk access was somehow blocked. Opening new terminals within
Konsole yielded in red letters. "unable to start /bin/bash" after a
few seconds.
I rebooted using the reset button, Alt+Print+S didn''t seem to sync
anything to the disk - I tried. The system booted up just fine, some
error messages about unusable free space caches came up but it booted
up into the login manager. However, I can no longer login: KDE startup
freezes the system. If I ssh into the box first, I can see some dmesg
output related to "bad blocks" and some "transid" errors. So
I did a
scrub, this is what I get:

I was able to rsync my /home to the original partition I created my
btrfs from about 2 weeks ago, so this is not a complete desaster - but
with many of these logged to dmesg:

I''m on Gentoo, using gentoo-sources 3.0.4 in the backup system (the
btrfs system runs on 3.0.6):
# uname -a
Linux jupiter 3.0.4-gentoo #1 SMP Sat Oct 1 17:20:43 CEST 2011 i686
Intel(R) Pentium(R) 4 CPU 3.20GHz GenuineIntel GNU/Linux
The btrfs partition consists of multiple sub volumes. I would not
loose my /home as I was able to sync it but I would loose the rest of
the file system which includes a complete Gentoo installation and some
big data files only recoverable by investing much time. So I''d love to
get rid of the problems scrub complains about. I don''t mind if I would
have to delete some files which I can probably recover easily. But I
can simply find no way to identify these files. Is there a way to map
the above error messages to file system pathes?
Just for completeness, here''s my fstab with mount options (the relevant
part):
/dev/sdd3 / btrfs compress=lzo,autodefrag,subvol=root 0 1
/dev/sdd3 /home btrfs compress=lzo,autodefrag,subvol=home 0 2
/dev/sdd3 /usr/portage btrfs compress=lzo,autodefrag,subvol=portage 0 2

/dev/sdd3 /mnt/btrfs-subvol-0 btrfs
compress=lzo,subvolid=0,autodefrag,noauto 0 2
I got rid of the free space caching issues by mounting with
clear_cache. Memory of the system is stable (memtest86 does not report
errors). The hard disk is fresh from factory, no errors reported in
smartctl and no sector errors reported in dmesg. When the problem in
"cp --reflink" occured I know there was a backtrace in dmesg related
to btrfs but I was not able to capture it. Btrfs was created with meta
data mirroring and user data striping although the fs is single disk
only currently. I planned to add more disks when btrfs proves stable
for me.
Thanks in advance,
Kai

Is there a way to map > the above error messages to file system pathes?I figured out that most of the affected files are located in the Google Chromium cache. Trying to "cat" all files there showed up the csum errors in dmesg but the system stays stable. I decided to simply delete the cache, however that makes "rm" becoming killed. Here''s the dmesg output from the "rm -Rf .cache/chromium/*" session: [ 637.297845] verify_parent_transid: 470 callbacks suppressed [ 637.297852] parent transid verify failed on 641086160896 wanted 43863 found 43873 [ 637.298833] parent transid verify failed on 641086160896 wanted 43863 found 43873 [ 637.315081] parent transid verify failed on 641086160896 wanted 43863 found 43873 [ 637.345259] parent transid verify failed on 641086160896 wanted 43863 found 43873 [ 637.345269] parent transid verify failed on 641086160896 wanted 43863 found 43873 [ 637.345296] BUG: unable to handle kernel NULL pointer dereference at 0000001c [ 637.345306] IP: [<c1142c2f>] btrfs_print_leaf+0xd/0x886 [ 637.345319] *pde = 00000000 [ 637.345324] Oops: 0000 [#1] SMP [ 637.345330] Modules linked in: af_packet vmnet vmblock vsock vmci vmmon lm90 it87 hwmon_vid hwmon fuse rfcomm bnep snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device snd_pcm_oss snd_mixer_oss reiserfs zram(C) mperf loop emu10k1_gp sidewinder joydev nfs lockd auth_rpcgss nfs_acl sunrpc ipv6 tcp_cubic nvidia(P) snd_usb_audio snd_usbmidi_lib i82875p_edac usb_storage usbhid 8250_pnp gspca_sonixj gspca_main videodev firewire_ohci edac_core uas hid firewire_core sr_mod cdrom sg ns558 btusb analog evdev pcspkr ne2k_pci 8390 floppy gameport i2c_i801 8250 parport_pc serial_core parport e1000 intel_agp snd_mpu401 snd_mpu401_uart thermal bluetooth crc16 crc_itu_t fan processor button intel_gtt agpgart unix [last unloaded: microcode] [ 637.345434] [ 637.345439] Pid: 2465, comm: btrfs-delayed-m Tainted: P A C 3.0.6-gentoo #1 /8KNXP [ 637.345446] EIP: 0060:[<c1142c2f>] EFLAGS: 00010286 CPU: 1 [ 637.345450] EIP is at btrfs_print_leaf+0xd/0x886 [ 637.345454] EAX: f506a800 EBX: f506a800 ECX: 00418335 EDX: 00000000 [ 637.345457] ESI: 00000000 EDI: f4c40850 EBP: fffffffb ESP: f49d7d30 [ 637.345460] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 [ 637.345464] Process btrfs-delayed-m (pid: 2465, ti=f49d6000 task=f4707800 task.ti=f49d6000) [ 637.345467] Stack: [ 637.345469] f499e840 f505e000 000000b2 00000000 00000000 ffffffff 00000000 00000000 [ 637.345478] 00000100 00000000 0006cac6 00000000 c113b1ec c101e917 f506a800 c1350707 [ 637.345487] 11d22000 00000128 00060000 00008050 2811d220 a8000001 00040000 00000000 [ 637.345496] Call Trace: [ 637.345502] [<c113b1ec>] ?
