Re: FYI: Kernel crash info
Hi Henk! Thanks for clarification! Its indeed an Seagate Archive 8TB drive. So it is vital info to let the drive settle down a bit when using it at least in an HotPlug or USB szenario sash Am 11.05.2016 um 03:02 schrieb Henk Slager: > On Tue, May 10, 2016 at 9:35 PM,wrote: >> He guys! >> >> >> while testing/stressing (dd'ing 200GB random to the drive) a brand new >> 8TB seagate drive i ran into an kernel ooops. >> >> i think it happend after i finished dd'ing and while removing the drive. >> saw it a few minutes afterwards. > Strictly speaking, this is not a kernel crash, it is just a failure to > write to the device and reporting an IO error and file system going > read-only as a result. > > What does dmesg | grep ST8000 show? > > If this 8TB is an SMR drive ('Archive'), be aware that under certain > circumstances, like for example unplugging/unpowering too fast after > massive random writes, this kind of IO failures are to be expected. > > >> uname -a >> Linux MacBookPro 4.4.0-22-generic #39~14.04.1-Ubuntu SMP Thu May 5 >> 19:19:06 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux >> master@MacBookPro:~$ btrfs --version >> btrfs-progs v4.4 >> >> >> [ 6971.087519] BTRFS: error (device sdb1) in >> btrfs_commit_transaction:2124: errno=-5 IO failure (Error while writing >> out transaction) >> [ 6971.087525] BTRFS info (device sdb1): forced readonly >> [ 6971.087528] BTRFS warning (device sdb1): Skipping commit of aborted >> transaction. >> [ 6971.087530] [ cut here ] >> [ 6971.087559] WARNING: CPU: 1 PID: 8161 at >> /build/linux-lts-xenial-T5gd_J/linux-lts-xenial-4.4.0/fs/btrfs/transaction.c:1746 >> cleanup_transaction+0x87/0x2e0 [btrfs]() >> [ 6971.087561] BTRFS: Transaction aborted (error -5) >> [ 6971.087563] Modules linked in: ufs qnx4 hfsplus hfs minix ntfs msdos >> jfs xfs libcrc32c cpuid uas usb_storage ipt_MASQUERADE >> nf_nat_masquerade_ipv4 iptable_nat nf_nat_ipv4 nf_nat nf_conntrack_ipv4 >> nf_defrag_ipv4 xt_conntrack nf_conntrack ipt_REJECT nf_reject_ipv4 >> xt_CHECKSUM iptable_mangle xt_tcpudp bridge stp llc ip6table_filter >> ip6_tables iptable_filter ip_tables ebtable_nat ebtables x_tables >> rpcsec_gss_krb5 nfsv4 rfcomm bnep nfsd auth_rpcgss nfs_acl nfs lockd >> grace sunrpc fscache intel_rapl x86_pkg_temp_thermal intel_powerclamp >> joydev coretemp applesmc kvm_intel input_polldev kvm irqbypass >> crct10dif_pclmul snd_hda_codec_cirrus snd_hda_codec_generic >> snd_hda_codec_hdmi crc32_pclmul dm_multipath aesni_intel uvcvideo >> aes_x86_64 videobuf2_vmalloc lrw videobuf2_memops btusb gf128mul >> snd_seq_midi videobuf2_v4l2 glue_helper btrtl snd_seq_midi_event >> snd_hda_intel ablk_helper videobuf2_core v4l2_common btbcm cryptd >> snd_rawmidi snd_hda_codec btintel videodev snd_hda_core hid_appleir >> bluetooth wl(POE) snd_hwdep lpc_ich snd_pcm input_leds snd_seq cfg80211 >> media bcm5974 snd_seq_device snd_timer snd soundcore acpi_als sbs >> kfifo_buf apple_gmux industrialio sbshc mac_hid mei_me parport_pc >> apple_bl mei shpchp ppdev lp parport btrfs xor raid6_pq hid_generic >> hid_apple usbhid hid amdkfd amd_iommu_v2 radeon i2c_algo_bit ttm >> drm_kms_helper syscopyarea sysfillrect sysimgblt tg3 fb_sys_fops drm >> firewire_ohci ptp firewire_core pata_acpi pps_core crc_itu_t video fjes >> [ 6971.087672] CPU: 1 PID: 8161 Comm: umount Tainted: P OE >> 4.4.0-22-generic #39~14.04.1-Ubuntu >> [ 6971.087675] Hardware name: Apple Inc. >> MacBookPro8,3/Mac-942459F5819B171B, BIOS >> MBP81.88Z.0047.B2C.1510261540 10/26/15 >> [ 6971.087677] 88045806fc38 813cde6c >> 88045806fc80 >> [ 6971.087681] c04741c0 88045806fc70 8107d856 >> 88045b52f960 >> [ 6971.087684] 88045ab22800 88045b5a6000 fffb >> fffb >> [ 6971.087687] Call Trace: >> [ 6971.087694] [] dump_stack+0x63/0x87 >> [ 6971.087699] [] warn_slowpath_common+0x86/0xc0 >> [ 6971.087703] [] warn_slowpath_fmt+0x4c/0x50 >> [ 6971.087722] [] cleanup_transaction+0x87/0x2e0 [btrfs] >> [ 6971.087727] [] ? prepare_to_wait_event+0xf0/0xf0 >> [ 6971.087731] [] ? __wake_up+0x44/0x50 >> [ 6971.087750] [] >> btrfs_commit_transaction+0x267/0xa80 [btrfs] >> [ 6971.087764] [] btrfs_sync_fs+0x55/0x110 [btrfs] >> [ 6971.087768] [] sync_filesystem+0x71/0xa0 >> [ 6971.087773] [] generic_shutdown_super+0x27/0x100 >> [ 6971.087776] [] kill_anon_super+0x12/0x20 >> [ 6971.087790] [] btrfs_kill_super+0x18/0x120 [btrfs] >> [ 6971.087794] [] deactivate_locked_super+0x43/0x70 >> [ 6971.087797] [] deactivate_super+0x46/0x60 >> [ 6971.087801] [] cleanup_mnt+0x3f/0x80 >> [ 6971.087805] [] __cleanup_mnt+0x12/0x20 >> [ 6971.087809] [] task_work_run+0x77/0x90 >> [ 6971.087812] [] exit_to_usermode_loop+0x73/0xa2 >> [ 6971.087816] [] syscall_return_slowpath+0x4e/0x60 >> [ 6971.087820] [] int_ret_from_sys_call+0x25/0x8f >> [ 6971.087823] ---[ end trace 02b0451a7c4939ae ]--- >> [ 6971.087826] BTRFS: error (device sdb1)

Strictly speaking, this is not a kernel crash, it is just a failure to write to the device and reporting an IO error and file system going read-only as a result. What does dmesg | grep ST8000 show? If this 8TB is an SMR drive ('Archive'), be aware that under certain circumstances, like for example unplugging/unpowering too fast after massive random writes, this kind of IO failures are to be expected. > uname -a > Linux MacBookPro 4.4.0-22-generic #39~14.04.1-Ubuntu SMP Thu May 5 > 19:19:06 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux > master@MacBookPro:~$ btrfs --version > btrfs-progs v4.4 > > > [ 6971.087519] BTRFS: error (device sdb1) in > btrfs_commit_transaction:2124: errno=-5 IO failure (Error while writing > out transaction) > [ 6971.087525] BTRFS info (device sdb1): forced readonly > [ 6971.087528] BTRFS warning (device sdb1): Skipping commit of aborted > transaction. > [ 6971.087530] [ cut here ] > [ 6971.087559] WARNING: CPU: 1 PID: 8161 at > /build/linux-lts-xenial-T5gd_J/linux-lts-xenial-4.4.0/fs/btrfs/transaction.c:1746 > cleanup_transaction+0x87/0x2e0 [btrfs]() > [ 6971.087561] BTRFS: Transaction aborted (error -5) > [ 6971.087563] Modules linked in: ufs qnx4 hfsplus hfs minix ntfs msdos > jfs xfs libcrc32c cpuid uas usb_storage ipt_MASQUERADE > nf_nat_masquerade_ipv4 iptable_nat nf_nat_ipv4 nf_nat nf_conntrack_ipv4 > nf_defrag_ipv4 xt_conntrack nf_conntrack ipt_REJECT nf_reject_ipv4 > xt_CHECKSUM iptable_mangle xt_tcpudp bridge stp llc ip6table_filter > ip6_tables iptable_filter ip_tables ebtable_nat ebtables x_tables > rpcsec_gss_krb5 nfsv4 rfcomm bnep nfsd auth_rpcgss nfs_acl nfs lockd > grace sunrpc fscache intel_rapl x86_pkg_temp_thermal intel_powerclamp > joydev coretemp applesmc kvm_intel input_polldev kvm irqbypass > crct10dif_pclmul snd_hda_codec_cirrus snd_hda_codec_generic > snd_hda_codec_hdmi crc32_pclmul dm_multipath aesni_intel uvcvideo > aes_x86_64 videobuf2_vmalloc lrw videobuf2_memops btusb gf128mul > snd_seq_midi videobuf2_v4l2 glue_helper btrtl snd_seq_midi_event > snd_hda_intel ablk_helper videobuf2_core v4l2_common btbcm cryptd > snd_rawmidi snd_hda_codec btintel videodev snd_hda_core hid_appleir > bluetooth wl(POE) snd_hwdep lpc_ich snd_pcm input_leds snd_seq cfg80211 > media bcm5974 snd_seq_device snd_timer snd soundcore acpi_als sbs > kfifo_buf apple_gmux industrialio sbshc mac_hid mei_me parport_pc > apple_bl mei shpchp ppdev lp parport btrfs xor raid6_pq hid_generic > hid_apple usbhid hid amdkfd amd_iommu_v2 radeon i2c_algo_bit ttm > drm_kms_helper syscopyarea sysfillrect sysimgblt tg3 fb_sys_fops drm > firewire_ohci ptp firewire_core pata_acpi pps_core crc_itu_t video fjes > [ 6971.087672] CPU: 1 PID: 8161 Comm: umount Tainted: P OE > 4.4.0-22-generic #39~14.04.1-Ubuntu > [ 6971.087675] Hardware name: Apple Inc. > MacBookPro8,3/Mac-942459F5819B171B, BIOS > MBP81.88Z.0047.B2C.1510261540 10/26/15 > [ 6971.087677] 88045806fc38 813cde6c > 88045806fc80 > [ 6971.087681] c04741c0 88045806fc70 8107d856 > 88045b52f960 > [ 6971.087684] 88045ab22800 88045b5a6000 fffb > fffb > [ 6971.087687] Call Trace: > [ 6971.087694] [] dump_stack+0x63/0x87 > [ 6971.087699] [] warn_slowpath_common+0x86/0xc0 > [ 6971.087703] [] warn_slowpath_fmt+0x4c/0x50 > [ 6971.087722] [] cleanup_transaction+0x87/0x2e0 [btrfs] > [ 6971.087727] [] ? prepare_to_wait_event+0xf0/0xf0 > [ 6971.087731] [] ? __wake_up+0x44/0x50 > [ 6971.087750] [] > btrfs_commit_transaction+0x267/0xa80 [btrfs] > [ 6971.087764] [] btrfs_sync_fs+0x55/0x110 [btrfs] > [ 6971.087768] [] sync_filesystem+0x71/0xa0 > [ 6971.087773] [] generic_shutdown_super+0x27/0x100 > [ 6971.087776] [] kill_anon_super+0x12/0x20 > [ 6971.087790] [] btrfs_kill_super+0x18/0x120 [btrfs] > [ 6971.087794] [] deactivate_locked_super+0x43/0x70 > [ 6971.087797] [] deactivate_super+0x46/0x60 > [ 6971.087801] [] cleanup_mnt+0x3f/0x80 > [ 6971.087805] [] __cleanup_mnt+0x12/0x20 > [ 6971.087809] [] task_work_run+0x77/0x90 > [ 6971.087812] [] exit_to_usermode_loop+0x73/0xa2 > [ 6971.087816] [] syscall_return_slowpath+0x4e/0x60 > [ 6971.087820] [] int_ret_from_sys_call+0x25/0x8f > [ 6971.087823] ---[ end trace 02b0451a7c4939ae ]--- > [ 6971.087826] BTRFS: error (device sdb1) in cleanup_transaction:1746: > errno=-5 IO failure > [ 6971.087828] BTRFS info (device sdb1): delayed_refs has NO entry > [ 6973.206207] BTRFS error (device sdb1): cleaner transaction attach > returned -30 > > > master@MacBookPro:~$ apt-cache show linux-image-generic-lts-xenial > Package: linux-image-generic-lts-xenial > Priority: optional >
