Hi, I just hit a XFS crash [1] when I tested XFS on a 500T storage. And a XFS corruption [2] can be found by "xfs_repair -n". Tested on 4.17-rc6, xfsprogs-4.16.1. mkfs.xfs options are "-m crc=1,finobt=1, rmapbt=1,reflink=1 -i sparse=1". I've report a bug as below: https://bugzilla.kernel.org/show_bug.cgi?id=199825 [1] kernel: XFS: Assertion failed: XFS_FORCED_SHUTDOWN(ip->i_mount) || ip->i_delayed_blks == 0, file: fs/xfs/xfs_super.c, line: 984 kernel: WARNING: CPU: 39 PID: 487 at fs/xfs/xfs_message.c:105 asswarn+0x1e/0x30 [xfs] kernel: Modules linked in: loop intel_powerclamp coretemp kvm_intel sunrpc kvm irqbypass crct10dif_pclmul crc32_pclmul ghash_clmulni_intel pcbc aesni_intel crypto_simd cryptd glue_helper iTCO_wdt gpio_ich iTCO_vendor_support dm_service_time pcspkr ipmi_ssif ipmi_si ipmi_devintf hpilo hpwdt sg i7core_edac lpc_ich ipmi_msghandler shpchp acpi_power_meter pcc_cpufreq dm_multipath ip_tables xfs libcrc32c sr_mod cdrom ata_generic pata_acpi radeon i2c_algo_bit drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops ttm ata_piix sd_mod drm mpt3sas libata crc32c_intel serio_raw hpsa netxen_nic i2c_core raid_class scsi_transport_sas dm_mirror dm_region_hash dm_log dm_mod kernel: CPU: 39 PID: 487 Comm: kswapd0 Not tainted 4.17.0-rc6+ #2 kernel: Hardware name: HP ProLiant DL580 G7, BIOS P65 10/01/2013 kernel: RIP: 0010:asswarn+0x1e/0x30 [xfs] kernel: RSP: 0018:ffff9b9887d9fbc0 EFLAGS: 00010246 kernel: RAX: 0000000000000000 RBX: ffff882b91e009d8 RCX: 0000000000000000 kernel: RDX: ffff9b9887d9fae0 RSI: 000000000000000a RDI: ffffffffc05ecff9 kernel: RBP: ffff882b91e008c8 R08: 0000000000000000 R09: 0000000000000021 kernel: R10: 0000000000000000 R11: 000000000000000a R12: ffff882b91e00780 kernel: R13: 000000000000ce58 R14: 000000000000000c R15: 00000000000000e5 kernel: FS: 0000000000000000(0000) GS:ffff882f6fbc0000(0000) knlGS:0000000000000000 kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 kernel: CR2: 00007f832588eff0 CR3: 0000000a2dc0a002 CR4: 00000000000206e0 kernel: Call Trace: kernel: xfs_fs_destroy_inode+0x1db/0x200 [xfs] kernel: dispose_list+0x48/0x60 kernel: prune_icache_sb+0x52/0x70 kernel: super_cache_scan+0x139/0x190 kernel: shrink_slab+0x249/0x430 kernel: shrink_node+0x44a/0x490 kernel: balance_pgdat+0x188/0x360 kernel: kswapd+0x171/0x410 kernel: ? remove_wait_queue+0x60/0x60 kernel: kthread+0xf8/0x130 kernel: ? balance_pgdat+0x360/0x360 kernel: ? kthread_bind+0x10/0x10 kernel: ret_from_fork+0x35/0x40 kernel: Code: 99 f9 ff ff 0f 0b e8 c2 d4 4e c8 66 90 66 66 66 66 90 48 89 f1 41 89 d0 48 c7 c6 08 7f 5f c0 48 89 fa 31 c0 31 ff e8 b2 fc ff ff <0f> 0b c3 0f 1f 44 00 00 66 2e 0f 1f 84 00 00 00 00 00 66 66 66 kernel: ---[ end trace 6d72efdc406c28bc ]--- [2] Phase 1 - find and verify superblock... - reporting progress in intervals of 15 minutes Memory available for repair (48300MB) may not be sufficient.
