http://bugzilla.opensuse.org/show_bug.cgi?id=934464 Bug ID: 934464 Summary: btrfs partition converted from ext4 becomes read-only minutes after booting: WARNING: CPU: 2 PID: 2777 at ../fs/btrfs/super.c:260 __btrfs_abort_transaction+0x4b/0x120 [btrfs]() Classification: openSUSE Product: openSUSE Factory Version: 201505* Hardware: x86-64 OS: SUSE Other Status: NEW Severity: Major Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: robert.munteanu@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I have TW install which used to have a ext4 / partition. Using a rescue TW USB stick ( created about 2-3 weeks ago ) I converted that partition to btrfs. I did a balance and defrag ( in that order ) , both when the fs was mounted. After logging in to KDE I quickly get a read-only filesystem. I've pasted the backtrace below Jun 11 23:13:08 mars kernel: WARNING: CPU: 2 PID: 2777 at ../fs/btrfs/super.c:260 __btrfs_abort_transaction+0x4b/0x120 [btrfs]() Jun 11 23:13:08 mars kernel: BTRFS: Transaction aborted (error -95) Jun 11 23:13:08 mars kernel: Modules linked in: bnep bluetooth rfkill fuse vboxpci(O) vboxnetadp(O) vboxnetflt(O) vboxdrv(O) af_packet nf_log_ipv6 xt_pkttype nf_log_ip v4 nf_log_common xt_LOG xt_limit ip6t_REJECT xt_tcpudp nf_conntrack_ipv6 nf_defrag_ipv6 ip6table_raw ipt_REJECT iptable_raw xt_CT iptable_filter ip6table_mangle nf_con ntrack_netbios_ns nf_conntrack_broadcast nf_conntrack_ipv4 nf_defrag_ipv4 ip_tables xt_conntrack nf_conntrack ip6table_filter ip6_tables x_tables xfs libcrc32c snd_hda _codec_hdmi raid1 md_mod gpio_ich ppdev iTCO_wdt iTCO_vendor_support coretemp snd_hda_codec_realtek snd_hda_codec_generic kvm_intel snd_hda_intel dm_mod kvm snd_hda_co ntroller snd_hda_codec snd_hwdep serio_raw pcspkr snd_pcm i2c_i801 snd_seq joydev snd_seq_device snd_timer snd 8250_fintek parport_pc parport acpi_cpufreq lpc_ich Jun 11 23:13:08 mars kernel: soundcore mfd_core shpchp processor ata_generic btrfs hid_logitech_hidpp xor raid6_pq sr_mod cdrom nvidia_uvm(PO) nvidia(PO) firewire_ohc i firewire_core crc_itu_t uas usb_storage r8169 mii pata_jmicron hid_logitech_dj drm button sg Jun 11 23:13:08 mars kernel: CPU: 2 PID: 2777 Comm: kworker/u8:0 Tainted: P O 4.0.4-3-desktop #1 Jun 11 23:13:08 mars kernel: Hardware name: Gigabyte Technology Co., Ltd.
