Date: Thu, 22 Mar 2007 12:24:12 -0700 From: "Phy Prabab" <phyprabab@...il.com> To: linux-kernel@...r.kernel.org Subject: Opps in 2.6.21-rc4 nfsd Hello, I have a recent oopps on a small file server I have running. The machine in question is a dual, dual core AMD Opteron 2.2GHz w/4G RAM, 3Ware 9650SE (14 drive RAID 10), using XFS, LVM2 (latest), exported via knfsd. Kernel is 2.6.21-rc4 64b. Here is the bt: Mar 22 12:09:01 rcfs05 kernel: Modules linked in: Mar 22 12:09:01 rcfs05 kernel: Pid: 3102, comm: nfsd Not tainted 2.6.21-rc4-smp #3 Mar 22 12:09:01 rcfs05 kernel: RIP: 0010:[<ffffffff80350613>] [<ffffffff80350613>] fh_compose+0x3e3/0x4d0 Mar 22 12:09:01 rcfs05 kernel: RSP: 0018:ffff8101197fdd70 EFLAGS: 00010297 Mar 22 12:09:01 rcfs05 kernel: RAX: 0000000000000006 RBX: 000000000ee00004 RCX: 0000000000000000 Mar 22 12:09:01 rcfs05 kernel: RDX: 0000000000000018 RSI: ffff81011975a940 RDI: 0000000000000080 Mar 22 12:09:01 rcfs05 kernel: RBP: 0000000000000001 R08: 00000000ffffffff R09: 00002ba24f06ca50 Mar 22 12:09:01 rcfs05 kernel: R10: ffff81011975a808 R11: ffffffff8022f500 R12: ffff81011975a938 Mar 22 12:09:01 rcfs05 kernel: R13: 0000000000000006 R14: ffff81010eaab0c0 R15: ffff8100cc714940 Mar 22 12:09:01 rcfs05 kernel: FS: 00002b020c71b6d0(0000) GS:ffff81011dcf56c0(0000) knlGS:0000000000000000 Mar 22 12:09:01 rcfs05 kernel: CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b Mar 22 12:09:01 rcfs05 kernel: CR2: 0000000000000000 CR3: 00000001173d1000 CR4: 00000000000006e0 Mar 22 12:09:01 rcfs05 kernel: Process nfsd (pid: 3102, threadinfo ffff8101197fc000, task ffff81011b7ef020) Mar 22 12:09:01 rcfs05 kernel: Stack: ffff81010fa7b868 ffffffff80239d8a 0000000000000286 ffff810111aee5e8 Mar 22 12:09:01 rcfs05 kernel: ffff810105af2890 ffff81011975a808 ffff810105af2890 000000000eaab0c0 Mar 22 12:09:01 rcfs05 kernel: ffff810105af2890 ffff81011975a808 ffff810105af2890 000000000000000a Mar 22 12:09:01 rcfs05 kernel: Call Trace: Mar 22 12:09:01 rcfs05 kernel: [<ffffffff80239d8a>] __lookup_hash+0x7a/0x160 Mar 22 12:09:01 rcfs05 kernel: [<ffffffff803547a5>] nfsd_lookup+0x435/0x4d0 Mar 22 12:09:01 rcfs05 kernel: [<ffffffff8035aaa8>] nfsd3_proc_lookup+0xe8/0x110 Mar 22 12:09:01 rcfs05 kernel: [<ffffffff8034d69d>] nfsd_dispatch+0xfd/0x1f0 Mar 22 12:09:01 rcfs05 kernel: [<ffffffff80608094>] svc_process+0x3e4/0x730 Mar 22 12:09:01 rcfs05 kernel: [<ffffffff8026bbf2>] __down_read+0x12/0xa2 Mar 22 12:09:01 rcfs05 kernel: [<ffffffff8034dd00>] nfsd+0x1a0/0x2d0 Mar 22 12:09:01 rcfs05 kernel: [<ffffffff80264f38>] child_rip+0xa/0x12 Mar 22 12:09:01 rcfs05 kernel: [<ffffffff8034db60>] nfsd+0x0/0x2d0 Mar 22 12:09:01 rcfs05 kernel: [<ffffffff80264f2e>] child_rip+0x0/0x12 Mar 22 12:09:01 rcfs05 kernel: Mar 22 12:09:01 rcfs05 kernel: Mar 22 12:09:01 rcfs05 kernel: Code: 48 8b 01 ba 10 00 00 00 bf 10 00 00 00 48 89 06 48 8b 41 08 Mar 22 12:09:01 rcfs05 kernel: RIP [<ffffffff80350613>] fh_compose+0x3e3/0x4d0 Mar 22 12:09:01 rcfs05 kernel: RSP <ffff8101197fdd70> Mar 22 12:09:01 rcfs05 kernel: CR2: 0000000000000000 Once this oops happens, the machine is still usable, however NFS crawls to a halt (in fact one of the machines with a mount point of this machine, failed to respond anymore - I assume that thread is the one that ooops'ed).
