Hi, When inode_cache was specified for the mount option, I encountered the following messages at umount. Step to reproduce: mkfs.btrfs -f /dev/sdc4 mount -o compress=lzo,autodefrag,inode_cache /dev/sdc4 /test1 dd if=/dev/zero of=/test1/file1 bs=1M count=8192 dd if=/test1/file1 of=/dev/null bs=1M rm -f /test1/file1 umount /test1 Thanks, Tsutomu ========================================================================================== Apr 3 09:42:29 luna kernel: [ 511.911342] btrfs: use lzo compression Apr 3 09:42:29 luna kernel: [ 511.911348] btrfs: enabling auto defrag Apr 3 09:42:29 luna kernel: [ 511.911352] btrfs: enabling inode map caching Apr 3 09:42:29 luna kernel: [ 511.911353] btrfs: disk space caching is enabled Apr 3 09:43:12 luna kernel: [ 554.638768] ------------[ cut here ]------------ Apr 3 09:43:12 luna kernel: [ 554.638815] WARNING: at fs/btrfs/super.c:255 __btrfs_abort_transaction+0x55/0xdc [btrfs]() Apr 3 09:43:12 luna kernel: [ 554.638818] Hardware name: PRIMERGY Apr 3 09:43:12 luna kernel: [ 554.638822] Modules linked in: btrfs(O) raid6_pq zlib_deflate xor crc32c libcrc32c ebtable_nat ebtables bnx2i cnic uio xt_CHECKSUM cxgb4i iptable_mangle cxgb4 cxgb3i cxgb3 mdio libcxgbi bridge stp llc iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi nfsd auth_rpcgss acpi_cpufreq mperf vhost_net freq_table coretemp tun nfs_acl lockd kvm dm_mirror dm_region_hash iTCO_wdt dm_log dm_mod iTCO_vendor_support tg3 shpchp sunrpc lpc_ich mfd_core ptp pci_hotplug i3000_edac edac_core pps_core microcode i2c_i801 pcspkr i2c_core uinput ipv6 autofs4 ext4 crc16 jbd2 mbcache sr_mod cdrom sd_mod crc_t10dif ata_piix libata megaraid_sas scsi_mod Apr 3 09:43:12 luna kernel: [ 554.638898] Pid: 1749, comm: btrfs-transacti Tainted: G O 3.9.0-rc5 #1 Apr 3 09:43:12 luna kernel: [ 554.638900] Call Trace: Apr 3 09:43:12 luna kernel: [ 554.638909] [<ffffffff8103e52f>] warn_slowpath_common+0x83/0x9e Apr 3 09:43:12 luna kernel: [ 554.638914] [<ffffffff8103e5ed>] warn_slowpath_fmt+0x46/0x48 Apr 3 09:43:12 luna kernel: [ 554.638931] [<ffffffffa040db62>] __btrfs_abort_transaction+0x55/0xdc [btrfs] Apr 3 09:43:12 luna kernel: [ 554.638960] [<ffffffffa04601e4>] ? btrfs_truncate_free_space_cache+0x6c/0x122 [btrfs] Apr 3 09:43:12 luna kernel: [ 554.638981] [<ffffffffa0426513>] btrfs_save_ino_cache+0x190/0x2f9 [btrfs] Apr 3 09:43:12 luna kernel: [ 554.639003] [<ffffffffa042cc6c>] commit_fs_roots.isra.27+0xa6/0x14e [btrfs] Apr 3 09:43:12 luna kernel: [ 554.639026] [<ffffffff81064690>] ? should_resched+0x9/0x28 Apr 3 09:43:12 luna kernel: [ 554.639045] [<ffffffff813dc287>] ? _cond_resched+0xe/0x22 Apr 3 09:43:12 luna kernel: [ 554.639079] [<ffffffffa042e434>] btrfs_commit_transaction+0x471/0x898 [btrfs] Apr 3 09:43:12 luna kernel: [ 554.639084] [<ffffffff8105a8d2>] ? bit_waitqueue+0x7a/0x7a Apr 3 09:43:12 luna kernel: [ 554.639106] [<ffffffffa0427820>] transaction_kthread+0xef/0x190 [btrfs] Apr 3 09:43:12 luna kernel: [ 554.639127] [<ffffffffa0427731>] ? try_to_freeze+0x32/0x32 [btrfs] Apr 3 09:43:12 luna kernel: [ 554.639130] [<ffffffff8105a2b9>] kthread+0x8d/0x95 Apr 3 09:43:12 luna kernel: [ 554.639134] [<ffffffff8105a22c>] ? __kthread_parkme+0x65/0x65 Apr 3 09:43:12 luna kernel: [ 554.639138] [<ffffffff813e3f2c>] ret_from_fork+0x7c/0xb0 Apr 3 09:43:12 luna kernel: [ 554.639142] [<ffffffff8105a22c>] ? __kthread_parkme+0x65/0x65 Apr 3 09:43:12 luna kernel: [ 554.639145] ---[ end trace ab791b60ae901bf9 ]--- Apr 3 09:43:12 luna kernel: [ 554.639149] BTRFS error (device sdc4) in btrfs_save_ino_cache:471: error 28 Apr 3 09:43:12 luna kernel: [ 554.639153] btrfs is forced readonly Apr 3 09:43:12 luna kernel: [ 554.640329] BTRFS warning (device sdc4): Skipping commit of aborted transaction.
