February 23, 201313 yr I run 5.0RC11 in 4 GB mode. After starting a Parity Check I see the following in my syslog: Feb 23 11:13:47 Tower1 kernel: INFO: rcu_sched self-detected stall on CPU { 0} (t=6000 jiffies) Feb 23 11:13:47 Tower1 kernel: Pid: 9369, comm: unraidd Not tainted 3.4.26-unRAID #2 Feb 23 11:13:47 Tower1 kernel: Call Trace: Feb 23 11:13:47 Tower1 kernel: [<c1057bca>] print_cpu_stall+0x6d/0xe5 Feb 23 11:13:47 Tower1 kernel: [<c1057c7d>] __rcu_pending+0x3b/0x138 Feb 23 11:13:47 Tower1 kernel: [<c1057df0>] rcu_check_callbacks+0x76/0xa1 Feb 23 11:13:47 Tower1 kernel: [<c102c982>] update_process_times+0x2d/0x58 Feb 23 11:13:47 Tower1 kernel: [<c104b11b>] tick_periodic+0x63/0x65 Feb 23 11:13:47 Tower1 kernel: [<c104b136>] tick_handle_periodic+0x19/0x6f Feb 23 11:13:47 Tower1 kernel: [<c10180d0>] smp_apic_timer_interrupt+0x6d/0x7f Feb 23 11:13:47 Tower1 kernel: [<c1342652>] apic_timer_interrupt+0x2a/0x30 Feb 23 11:13:47 Tower1 kernel: [<c1342040>] ? _raw_spin_unlock_irqrestore+0x8/0xa Feb 23 11:13:47 Tower1 kernel: [<f988bc8f>] unraid_end_request+0x64/0x6b [md_mod] Feb 23 11:13:47 Tower1 kernel: [<c10a965f>] bio_endio+0x25/0x27 Feb 23 11:13:47 Tower1 kernel: [<c11a052c>] req_bio_endio+0x80/0x88 Feb 23 11:13:47 Tower1 kernel: [<c1224f90>] ? put_device+0xf/0x11 Feb 23 11:13:47 Tower1 kernel: [<c11a0676>] blk_update_request+0x142/0x302 Feb 23 11:13:47 Tower1 kernel: [<c11a0844>] blk_update_bidi_request+0xe/0x4f Feb 23 11:13:47 Tower1 kernel: [<c11a1144>] blk_end_bidi_request+0x1d/0x53 Feb 23 11:13:47 Tower1 kernel: [<c11a11b9>] blk_end_request+0x12/0x14 Feb 23 11:13:47 Tower1 kernel: [<c12459d5>] scsi_end_request+0x1f/0x70 Feb 23 11:13:47 Tower1 kernel: [<c1245d3b>] scsi_io_completion+0x1a9/0x3fd Feb 23 11:13:47 Tower1 kernel: [<c1245ad9>] ? scsi_device_unbusy+0x7c/0x82 Feb 23 11:13:47 Tower1 kernel: [<c1240bfa>] scsi_finish_command+0x9d/0xa3 Feb 23 11:13:47 Tower1 kernel: [<c1246063>] scsi_softirq_done+0xc5/0xcd Feb 23 11:13:47 Tower1 kernel: [<c11a5652>] blk_done_softirq+0x4a/0x57 Feb 23 11:13:47 Tower1 kernel: [<c102862d>] __do_softirq+0x6b/0xfa Feb 23 11:13:47 Tower1 kernel: [<c10285c2>] ? irq_enter+0x41/0x41 Feb 23 11:13:47 Tower1 kernel: <IRQ> [<c1028476>] ? irq_exit+0x32/0x58 Feb 23 11:13:47 Tower1 kernel: [<c1003713>] ? do_IRQ+0x87/0x9b Feb 23 11:13:47 Tower1 kernel: [<c1342fa9>] ? common_interrupt+0x29/0x30 Feb 23 11:13:47 Tower1 kernel: [<f872ca49>] ? xor_sse_5+0x2b4/0x3d9 [xor] Feb 23 11:13:47 Tower1 kernel: [<c103cdfd>] ? check_preempt_curr+0x39/0x64 Feb 23 11:13:47 Tower1 kernel: [<f872d8cc>] ? xor_blocks+0x74/0x7c [xor] Feb 23 11:13:47 Tower1 kernel: [<f988ac94>] ? check_parity+0x96/0xcc [md_mod] Feb 23 11:13:47 Tower1 kernel: [<f988b8de>] ? handle_stripe+0xb30/0xdc1 [md_mod] Feb 23 11:13:47 Tower1 kernel: [<c102849a>] ? irq_exit+0x56/0x58 Feb 23 11:13:47 Tower1 kernel: [<c103d051>] ? __wake_up+0x3b/0x42 Feb 23 11:13:47 Tower1 kernel: [<f988bbe7>] ? unraidd+0x78/0xbc [md_mod] Feb 23 11:13:47 Tower1 kernel: [<f9888b31>] ? md_thread+0xcc/0xe3 [md_mod] Feb 23 11:13:47 Tower1 kernel: [<c10379b5>] ? wake_up_bit+0x5b/0x5b Feb 23 11:13:47 Tower1 kernel: [<f9888a65>] ? import_device+0x166/0x166 [md_mod] Feb 23 11:13:47 Tower1 kernel: [<c10376bc>] ? kthread+0x67/0x6c Feb 23 11:13:47 Tower1 kernel: [<c1037655>] ? kthread_freezable_should_stop+0x49/0x49 Feb 23 11:13:47 Tower1 kernel: [<c1342fb6>] ? kernel_thread_helper+0x6/0xd Feb 23 11:17:47 Tower1 kernel: INFO: rcu_sched self-detected stall on CPU { 0} (t=6000 jiffies) Feb 23 11:17:47 Tower1 kernel: Pid: 9369, comm: unraidd Not tainted 3.4.26-unRAID #2 Has something bad happened to the array? Are there memory problems? What does all of this mean? I have only SABNZBD, APCUPSD and SNAP running. Please help!!! Full syslog is attached. syslog-2013-02-23.zip
February 23, 201313 yr Author Rebooted the server and gave it the full 16 GB memory. The messages came back in the syslog after restarting the parity check. syslog-2013-02-23a.zip
February 23, 201313 yr No OOM as far as I can see... try and run without plugins to see where the issue lies.
February 23, 201313 yr Author Disabled the plugins but same happens again. Any more options? Funny thing is that during a parity rebuild last night I didn't see these errors, but now approx. 10 minutes after beginning a parity check they appear. syslog-2013-02-23b.zip
February 24, 201313 yr Author A parity sync/rebuild finished overnight again without problems. After starting the parity check the same errors in the syslog turned up. All addons are disabled and running with 16 GB memory. I don't know how this turns up, öut of the blue" Can it be an hardware error? Running baremetal now. Even when running stock like described in dgaschk's sig. latest syslog is attached syslog.zip
February 24, 201313 yr Author As of 14:47 the errors stopped appearing in the syslog. Don't know what caused this, just let the parity check run. One thing I noticed was that the unraidd process appeared at the top of top-screen with ove 50 %CPU. Don't see anything special in the latest syslog though. syslog2.zip
February 24, 201313 yr Sorry but there is way to much in there for me to understand... If its gone then be happy :-) Still think a memtest might be a good idea though.. Something weird was definately going on..
February 24, 201313 yr Try a memtest maybe ? Check the flashdrive for corruption also. Run memtest overnight. Run checkdisk on the flash in a PC or Mac. Does the problem occur when running bare-metal?
February 25, 201313 yr Author Try a memtest maybe ? Check the flashdrive for corruption also. Run memtest overnight. Run checkdisk on the flash in a PC or Mac. Does the problem occur when running bare-metal? Like stated previously: I am running baremetal. chkdsk found no problems
February 25, 201313 yr Author http://lime-technology.com/forum/index.php?topic=25425.msg221266#msg221266 Thanks for that. Panicking for nothing. Already informed Tom about it. No need to worry I guess.
