Can you descr= ibe > your setup in more detail? I created this btrfs filesystem on an arch linux system (amd64, quad=20 core) with kernel 2.3.38.1. it is on top of a md raid 5. [root@linuxserver ~]# cat /proc/mdstat Personalities : [raid6] [raid5] [raid4] md0 : active raid5 sde1[3] sdc1[1] sda1[0] sdf1[4] 5860535808 blocks super 1.2 level 5, 512k chunk, algorithm 2=20 [4/4] [UUUU] the raid was grown from 3 devices to 4, and then btrfs was grown to max= =20 size. mount options were clear_cache,compress-force. I was investigating a performance issue that i had, because over the=20 network i could only write to the filesystem at about 32mb/sec. when writing btrfs-delalloc- cpu usage was at 100%. While investigating i disabled compression, enabled space_cache and=20 tried zlib compression, and various combinations, while copying large=20 files back and forth using samba. BTW I tried to change some mount options using mount -o remount but=20 although the new options were printed on dmesg i think that they were=20 not enabled. I got the first error when i was copying some files and at the same tim= e=20 created a directory over samba. After a while i upgraded to 2.6.38.5 bu= t=20 nothing seems to have changed. I really dont think there is a hardware error here, but to be safe I am= =20 now running a check on the raid > > -chris > >> >> 2011 May 5 23:32:53 mail [ 200.580195] Oops: 0000 [#1] PREEMPT SMP >> 2011 May 5 23:32:53 mail [ 200.580220] last sysfs file: >> /sys/module/vt/parameters/default_utf8 >> 2011 May 5 23:32:53 mail [ 200.581145] Stack: >> 2011 May 5 23:32:53 mail [ 200.581276] Call Trace: >> 2011 May 5 23:32:53 mail [ 200.581732] Code: cc 00 00 48 8d 91 28 = e0 >> ff ff 48 89 e5 48 81 ec 90 00 00 00 48 89 5d d8 4c 89 65 e0 48 89 f3= 4c >> 89 6d e8 4c 89 75 f0 4c 89 7d f8<48> 8b 76 30 83 42 1c 01 48 b8 00 = 00 >> 00 00 00 16 00 00 48 01 f0 >> 2011 May 5 23:32:53 mail [ 200.583376] CR2: 0000000000000030 >> >> >> here is the part of dmesg that does not contain the thousands of >> parent transid verify failed messages >> >> >> May 5 23:32:51 mail kernel: [ 198.371084] parent transid verify fa= iled >> on 3062073683968 wanted 5181 found 5188 >> May 5 23:32:51 mail kernel: [ 198.371204] parent transid verify fa= iled >> on 3062073683968 wanted 5181 found 5188 >> May 5 23:32:53 mail kernel: [ 200.572774] Modules linked in: ipv6 >> btrfs zlib_deflate crc32c libcrc32c ext2 raid456 async_raid6_recov >> async_pq raid6_pq async_xor xor async_memcpy async_tx md_mod usb_sto= rage >> uas snd_seq_dummy snd_seq_oss radeon snd_seq_midi_event ttm snd_seq >> snd_hda_codec_hdmi snd_seq_device drm_kms_helper ohci_hcd snd_hda_in= tel >> snd_hda_codec snd_pcm_oss snd_hwdep drm i2c_algo_bit snd_mixer_oss >> snd_pcm i2c_piix4 snd_timer snd soundcore snd_page_alloc ehci_hcd wm= i >> i2c_core usbcore evdev processor button k10temp serio_raw pcspkr sg >> r8169 edac_core shpchp pci_hotplug edac_mce_amd mii sp5100_tco ext4 >> mbcache jbd2 crc16 sd_mod pata_acpi ahci libahci pata_atiixp libata = scsi_mod >> May 5 23:32:53 mail kernel: [ 200.572808] Pid: 1037, comm: >> btrfs-transacti Not tainted 2.6.38-ARCH #1 >> May 5 23:32:53 mail kernel: [ 200.572810] Call Trace: >> May 5 23:32:53 mail kernel: [ 200.572817] [] ?
