Dear Community, i have a linux server with a btrfs root filesystem. After some time, or a specific action (i don't know what exactly) it crashes. Sometimes it needs some day, sometimes when i make a concrete action, like subvolume delete, or make a new directory, etc. this is what i see from the dmesg output: [ 7595.865982] ------------[ cut here ]------------ [ 7595.865989] WARNING: at fs/btrfs/super.c:221 __btrfs_abort_transaction+0xc5/0xe0() [ 7595.865991] Hardware name: VMware Virtual Platform [ 7595.865992] btrfs: Transaction aborted [ 7595.865993] Modules linked in: [ 7595.865994] ipv6 iptable_filter ip_tables x_tables 8250_pnp vmwgfx 8250 ttm serial_core drm i2c_piix4 sr_mod ppdev parport_pc e1000 i2c_core cdrom pcspkr parport floppy ghash_clmulni_intel microcode [ 7595.866006] Pid: 13959, comm: btrfs Not tainted 3.5.4-gentoo-03 #1 [ 7595.866006] Call Trace: [ 7595.866010] [<ffffffff8103b589>] ? warn_slowpath_common+0x79/0xc0 [ 7595.866012] [<ffffffff8103b685>] ? warn_slowpath_fmt+0x45/0x50 [ 7595.866013] [<ffffffff81242f55>] ? __btrfs_abort_transaction+0xc5/0xe0 [ 7595.866016] [<ffffffff81270e04>] ? btrfs_unlink_subvol+0x204/0x360 [ 7595.866020] [<ffffffff8129b28e>] ? btrfs_ioctl_snap_destroy+0x39e/0x4f0 [ 7595.866021] [<ffffffff8129d1bb>] ? btrfs_ioctl+0x81b/0x1250 [ 7595.866024] [<ffffffff810259d2>] ? do_page_fault+0x182/0x440 [ 7595.866027] [<ffffffff8105ef63>] ? __wake_up+0x43/0x70 [ 7595.866030] [<ffffffff810fa1ef>] ? do_vfs_ioctl+0x8f/0x520 [ 7595.866033] [<ffffffff810e9d10>] ? vfs_write+0x140/0x190 [ 7595.866034] [<ffffffff810fa6c9>] ? sys_ioctl+0x49/0x80 [ 7595.866038] [<ffffffff815e8ca6>] ? system_call_fastpath+0x1a/0x1f [ 7595.866039] ---[ end trace 1d7d6e7d89b14907 ]--- [ 7595.866041] BTRFS error (device sda5) in btrfs_unlink_subvol:3176: error 28 [ 7595.866042] btrfs is forced readonly [ 7595.866044] BTRFS error (device sda5) in btrfs_ioctl_snap_destroy:2038: error 28 fwt portage # uname -a Linux fwt 3.5.4-gentoo-03 #1 SMP Thu Oct 4 20:13:12 CEST 2012 x86_64 Intel(R) Xeon(R) CPU X5650 @ 2.67GHz GenuineIntel GNU/Linux Please if you can help me how to stabilize the file system, as i use this as the root filesystem.
