This is : WARN_ON(!IS_ALIGNED(val, eb->fs_info->sectorsize)); in btrfs_set_device_total_bytes. This likely means your device's size isn't a multiple of sectorsize (4kb). Can you paste the output of btrfs inspect-internal dump-super /path/to/btrfs/device What i will advise you to do is to shrink your device to be a multiple of 4kb. In any case you can be assured that there is no danger of you losing data. > Modules linked in: rpcsec_gss_krb5 veth xt_nat xt_addrtype br_netfilter > xt_CHECKSUM ipt_MASQUERADE nf_nat_masquerade_ipv4 tun nf_conntrack_sane xt_CT > ip6t_rpfilter ip6t_REJECT nf_reject_ipv6 xt_conntrack ip_set nfnetlink > ebtable_nat ebtable_broute bridge stp llc ip6table_nat nf_conntrack_ipv6 > nf_defrag_ipv6 nf_nat_ipv6 ip6table_mangle ip6table_raw ip6table_security > iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack > libcrc32c iptable_mangle iptable_raw iptable_security ebtable_filter ebtables > ip6table_filter ip6_tables ftsteutates btrfs xor raid6_pq tda18212 cxd2841er > tpm_crb intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel > kvm iTCO_wdt irqbypass iTCO_vendor_support intel_cstate intel_uncore mei_wdt > intel_rapl_perf ppdev hci_uart ddbridge dvb_core > Okt 09 19:08:32 hypercloud.fritz.box kernel: btbcm btqca btintel mei_me > i2c_i801 shpchp bluetooth joydev mei intel_pch_thermal wmi intel_lpss_acpi > intel_lpss pinctrl_sunrisepoint fujitsu_laptop parport_pc sparse_keymap > ecdh_generic parport tpm_tis pinctrl_intel tpm_tis_core rfkill tpm acpi_pad > nfsd auth_rpcgss nfs_acl lockd grace sunrpc dm_crypt i915 crct10dif_pclmul > i2c_algo_bit crc32_pclmul drm_kms_helper crc32c_intel e1000e drm > ghash_clmulni_intel serio_raw ptp pps_core video i2c_hid > CPU: 3 PID: 22095 Comm: btrfs Tainted: G W > 4.13.4-200.fc26.x86_64 #1 > Hardware name: FUJITSU D3417-B1/D3417-B1, BIOS V5.0.0.11 R1.12.0 for > D3417-B1x 02/09/2016 > task: ffff8ecb59b026c0 task.stack: ffffb805cae90000 > RIP: 0010:btrfs_update_device+0x1be/0x1d0 [btrfs] > RSP: 0018:ffffb805cae93ac8 EFLAGS: 00010206 > RAX: 0000000000000fff RBX: ffff8ed094bb11c0 RCX: 0000074702251e00 > RDX: 0000000000000004 RSI: 0000000000003efa RDI: ffff8ec9eb032c08 > RBP: ffffb805cae93b10 R08: 0000000000003efe R09: ffffb805cae93a80 > R10: 0000000000001000 R11: 0000000000000003 R12: ffff8ed0c7a3f000 > R13: 0000000000000000 R14: 0000000000003eda R15: ffff8ec9eb032c08 > FS: 00007f10b256a8c0(0000) GS:ffff8ed0ee4c0000(0000) knlGS:0000000000000000 > CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 > CR2: 00007f6261c0d5f0 CR3: 00000005cad4c000 CR4: 00000000003406e0 > DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 > DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 > Call Trace: > btrfs_remove_chunk+0x365/0x870 [btrfs] > btrfs_relocate_chunk+0x7e/0xd0 [btrfs] > btrfs_balance+0xc07/0x1390 [btrfs] > btrfs_ioctl_balance+0x319/0x380 [btrfs] > btrfs_ioctl+0x9d5/0x24a0 [btrfs] > ? lru_cache_add+0x3a/0x80 > ? lru_cache_add_active_or_unevictable+0x4c/0xf0 > ? __handle_mm_fault+0x939/0x10b0 > do_vfs_ioctl+0xa5/0x600 > ? do_brk_flags+0x230/0x360 > ? do_vfs_ioctl+0xa5/0x600 > SyS_ioctl+0x79/0x90 > entry_SYSCALL_64_fastpath+0x1a/0xa5 > RIP: 0033:0x7f10b15e65e7 > RSP: 002b:00007ffc9402ebe8 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 > RAX: ffffffffffffffda RBX: 0000000000008041 RCX: 00007f10b15e65e7 > RDX: 00007ffc9402ec80 RSI: 00000000c4009420 RDI: 0000000000000003 > RBP: 00007f10b18abae0 R08: 000055b07a3b3010 R09: 0000000000000078 > R10: 00007f10b18abb38 R11: 0000000000000246 R12: 0000000000000000 > R13: 00007f10b18abb38 R14: 0000000000008060 R15: 0000000000000000 > Code: 4c 89 ff 45 31 c0 ba 10 00 00 00 4c 89 f6 e8 fa 20 ff ff 4c 89 ff e8 72 > ef fc ff e9 d3 fe ff ff 41 bd f4 ff ff ff e9 d0 fe ff ff <0f> ff eb b6 e8 39 > fd 78 c6 66 0f 1f 84 00 00 00 00 00 0f 1f 44 > ---[ end trace d1e1c8aff99bfeb8 ]--- > -- > To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in > the body of a message to majord...@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
