Package: linux-image-3.2.0-4-amd64 Version: 3.2.57-3+deb7u2 Severity: important
I'm running a redundant storage server pair with DRBD and LIO. On the secondary node I had some RAID card resets, which triggered DRBD to disconnect the node - but before that, requests were held for several seconds in the DRBD layer, which seems to be a problem for LIO (or maybe the subsequent initiator reconnects - I'm not sure). warning kernel: [1022062.839595] block drbd0: Remote failed to finish a request within ko-count * timeout info kernel: [1022062.839604] block drbd0: peer( Secondary -> Unknown ) conn( Connected -> Timeout ) pdsk( UpToDate -> DUnknown ) info kernel: [1022062.839697] block drbd0: new current UUID 9E9A652A9DC0D857:7115C7324E030315:8355E6AB18AD03EE:8354E6AB18AD03EF info kernel: [1022062.839957] block drbd0: asender terminated info kernel: [1022062.839962] block drbd0: Terminating drbd0_asender info kernel: [1022062.840629] block drbd0: Connection closed info kernel: [1022062.840636] block drbd0: conn( Timeout -> Unconnected ) info kernel: [1022062.840641] block drbd0: receiver terminated info kernel: [1022062.840644] block drbd0: Restarting drbd0_receiver info kernel: [1022062.840647] block drbd0: receiver (re)started info kernel: [1022062.840651] block drbd0: conn( Unconnected -> WFConnection ) emerg kernel: [1022062.840840] general protection fault: 0000 [#1] SMP warning kernel: [1022062.840986] CPU 5 warning kernel: [1022062.841028] Modules linked in: tcm_loop tcm_fc iscsi_target_mod target_core_pscsi target_core_file target_core_iblock target_core_mod netconsole parport_pc ppdev bnep rfcomm bluetooth rfkill lp parport drbd lru_cache libfc scsi_transport_fc scsi_tgt configfs uinput nfsd nfs nfs_acl auth_rpcgss fscache lockd sunrpc nf_conntrack_ipv6 nf_defrag_ipv6 ip6table_filter ip6_tables nf_conntrack_ipv4 nf_defrag_ipv4 xt_state nf_conntrack xt_tcpudp iptable_filter ip_tables x_tables loop snd_pcm snd_page_alloc snd_timer ioatdma acpi_cpufreq psmouse i7core_edac iTCO_wdt serio_raw mperf edac_core iTCO_vendor_support coretemp joydev evdev snd soundcore pcspkr processor i2c_i801 thermal_sys crc32c_intel button ext4 crc16 jbd2 mbcache dm_mod raid1 md_mod sg sd_mod ses enclosure crc_t10dif usbhid hid usb_storage uhci_hcd megaraid_sas ahci libahci libata scsi_mod ehci_hcd usbcore usb_common ixgbe mdio igb i2c_algo_bit i2c_core dca [last unloaded: target_core_mod] warning kernel: [1022062.845110] warning kernel: [1022062.845169] Pid: 5165, comm: iscsi_trx Not tainted 3.2.0-4-amd64 #1 Debian 3.2.57-3+deb7u2 Supermicro X8DT3/X8DT3 warning kernel: [1022062.845373] RIP: 0010:[<ffffffffa0442696>] [<ffffffffa0442696>] core_tmr_release_req+0x2c/0x66 [target_core_mod] warning kernel: [1022062.845514] RSP: 0018:ffff880314badd80 EFLAGS: 00010046 warning kernel: [1022062.845581] RAX: 0000000000000286 RBX: ffff8802ce58d7c0 RCX: dead000000100100 warning kernel: [1022062.845668] RDX: dead000000200200 RSI: 0000000000000286 RDI: ffff880329dc45d4 warning kernel: [1022062.845754] RBP: ffff880329dc45d4 R08: ffff880314badd60 R09: ffff8803155fc040 warning kernel: [1022062.845840] R10: ffff8803155fc040 R11: ffff8803155fc040 R12: ffff88032f365ae8 warning kernel: [1022062.845927] R13: ffff8803121d0ac0 R14: ffff88032f365a08 R15: ffff8803121d0ac0 warning kernel: [1022062.846014] FS: 0000000000000000(0000) GS:ffff88033fca0000(0000) knlGS:0000000000000000 warning kernel: [1022062.846103] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b warning kernel: [1022062.846170] CR2: 00007f73283f89de CR3: 0000000001605000 CR4: 00000000000006e0 warning kernel: [1022062.846257] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 warning kernel: [1022062.846344] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 warning kernel: [1022062.846430] Process iscsi_trx (pid: 5165, threadinfo ffff880314bac000, task ffff88032e951780) emerg kernel: [1022062.846519] Stack: warning kernel: [1022062.846577] 0000000000000282 ffff8803156517c0 ffff8803151ea800 ffffffffa0445b6e warning kernel: [1022062.846813] ffff88032f365800 ffffffffa053af12 0000000000000030 0000000000000001 warning kernel: [1022062.847046] ffff88032f365b68 ffff8803151ea800 0000000000000246 ffff88032f365800 emerg kernel: [1022062.847280] Call Trace: warning kernel: [1022062.847349] [<ffffffffa0445b6e>] ?
