Hi, I've got a btrfs array that ran into some trouble today. I noticed when I found a notice in the dmesg output: conftest[22330] trap divide error ip:400604 sp:7ffff2f1e5c8 error:0 in conftest[400000+1000] test_6321[7033]: segfault at 0 ip 0000000000400679 sp 00007fffaf6b42e0 error 4 in test_6321[400000+1000] bio too big device sdd1 (432 > 255) btrfs bad tree block start 9975698740868360051 421464846336 ------------[ cut here ]------------ kernel BUG at fs/btrfs/tree-log.c:3039! invalid opcode: 0000 [#1] last sysfs file: /sys/devices/virtual/hwmon/hwmon0/temp1_input CPU 0 Modules linked in: Pid: 26019, comm: afpd Not tainted 2.6.35-gentoo-r7-ferrous26 #1 M2A-VM/System Product Name RIP: 0010:[<ffffffff8113ab36>] [<ffffffff8113ab36>] 0xffffffff8113ab36 RSP: 0018:ffff88000a5d9e78 EFLAGS: 00010206 RAX: 00000000fffffffb RBX: ffff88007ad69000 RCX: dead000000200200 RDX: 000000000000001a RSI: ffff880051098f40 RDI: ffff88007da91940 RBP: ffff8800655e79c0 R08: ffff88000a5d9b18 R09: 0000000000000000 R10: ffff88007be52e28 R11: 0000000000000246 R12: ffff88001e34cd80 R13: ffff880048c1e1a0 R14: 00000000fffffffb R15: 0000000000004f49 FS: 00007f5b00a9a700(0000) GS:ffffffff813ce000(0000) knlGS:0000000055702d50 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 0000000000427830 CR3: 000000007b5ad000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process afpd (pid: 26019, threadinfo ffff88000a5d8000, task ffff88007647e7b0) Stack: ffff880048c1e1a0 ffff88007ad69000 ffff880000000000 ffff88007ad691c8 <0> ffff88007cd73400 0000000081054e5c 0000000000000001 ffff88007ad69000 <0> ffff880048c1e1a0 ffff880047ef9800 ffff88005ebb50c0 0000000001c43ce0 Call Trace: [<ffffffff8111da55>] ? 0xffffffff8111da55 [<ffffffff81092276>] ? 0xffffffff81092276 [<ffffffff81092327>] ? 0xffffffff81092327 [<ffffffff81092359>] ? 0xffffffff81092359 [<ffffffff81002768>] ? 0xffffffff81002768 Code: 89 de 4c 89 ef e8 78 f8 ff ff 85 c0 75 0f 49 8b 44 24 28 49 39 c4 74 2f 49 89 c4 eb 9f 41 89 c6 45 85 f6 79 22 41 83 fe e4 74 04 <0f> 0b eb fe 48 8b 83 20 01 00 00 49 8b 55 00 41 be 01 00 00 00 RIP [<ffffffff8113ab36>] 0xffffffff8113ab36 RSP <ffff88000a5d9e78> ---[ end trace f51e47b3ae49b500 ]--- bio too big device sdd1 (272 > 255) bio too big device sdd1 (1024 > 255) bio too big device sdd1 (1024 > 255) bio too big device sdd1 (744 > 255) Before I noticed this, I had tried to reboot the machine (but something seems to be blocking the reboot). I haven't done a hard reboot yet as I'm not sure if it would be safe. -- Mark Rada -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
