Hello, i've tried to get dmraid working with my setup, which is an Intel ICH7 (fake)raid5 on Ubuntu 7.04. RAID bus controller: Intel Corporation 82801GR/GH (ICH7 Family) Serial ATA Storage Controller RAID (rev 01) I've followed these instructions to get a patched kernel with the dm-raid4-5 module: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/97655/comments/5 dmraid info: root@Hypernode:~# dmraid -V dmraid version: 1.0.0.rc13 (2006.10.11) dmraid library version: 1.0.0.rc13 (2006.10.11) device-mapper version: 4.11.0 root@Hypernode:~# dmraid -s *** Group superset isw_chchibdjbf --> Subset name : isw_chchibdjbf_StorageRaid size : 1170211328 stride : 128 type : raid5_la status : ok subsets: 0 devs : 3 spares : 0 root@Hypernode:~# dmraid -r /dev/sda: isw, "isw_chchibdjbf", GROUP, ok, 586114701 sectors, data@ 0 /dev/sdb: isw, "isw_chchibdjbf", GROUP, ok, 586114701 sectors, data@ 0 /dev/sdc: isw, "isw_chchibdjbf", GROUP, ok, 586114701 sectors, data@ 0 The initscript supplied with the dmraid ubuntu package modprobes dm-mod only, so i've added modprobe dm-raid4-5 one line below. After loading those modules, the script executes dmraid --activate yes --ignorelocking, which failed resulting in locking up the machine. Here is what i've found in the syslog afterwards: [ 247.038792] raid5: automatically using best checksumming function: pIII_sse [ 247.054921] pIII_sse : 4015.000 MB/sec [ 247.054925] raid5: using function: pIII_sse (4015.000 MB/sec) [ 247.099256] device-mapper: dm-raid45: : initialized v0.1444 [ 254.728204] device-mapper: dm-raid45: : /dev/sda is raid disk 0 [ 254.728210] device-mapper: dm-raid45: : /dev/sdc is raid disk 1 [ 254.728214] device-mapper: dm-raid45: : /dev/sdb is raid disk 2 [ 254.728221] device-mapper: dm-raid45: : 128/128 sectors chunk/io size and 64 stripes [ 254.728225] device-mapper: dm-raid45: : algorithm "xor_asm", 2 chunks with 5261MB/s [ 254.728228] device-mapper: dm-raid45: : RAID5 (left asymmetric) set with net 2/3 devices [ 254.728336] BUG: unable to handle kernel NULL pointer dereference at virtual address 00000008 [ 254.728343] printing eip: [ 254.728345] c01301ce [ 254.728347] *pde = 00000000 [ 254.728350] Oops: 0002 [#1] [ 254.728352] SMP [ 254.728356] Modules linked in: dm_raid4_5 dm_region_hash dm_mem_cache xor ppdev capability commoncap cpufreq_powersave cpufreq_userspace cpufreq_stats cpufreq_ondemand freq_table cpufreq_conservative tc1100_wmi dev_acpi pcc_acpi sony_acpi video button sbs i2c_ec i2c_core battery asus_acpi backlight dock container ac nls_utf8 ntfs ipv6 sbp2 lp fuse snd_emu10k1_synth snd_emux_synth snd_seq_virmidi snd_seq_midi_emul snd_emu10k1 snd_ac97_codec ac97_bus snd_pcm_oss snd_mixer_oss snd_hda_intel snd_hda_codec snd_mpu401 snd_mpu401_uart snd_pcm snd_util_mem snd_hwdep snd_seq_dummy snd_seq_oss snd_seq_midi snd_rawmidi xpad snd_seq_midi_event snd_seq sk98lin analog pcspkr psmouse snd_timer snd_seq_device iTCO_wdt iTCO_vendor_support b1pci b1dma b1 serio_raw parport_pc parport snd kernelcapi af_packet shpchp pci_hotplug soundcore snd_page_alloc emu10k1_gp gameport tsdev evdev ext3 jbd mbcache dm_mirror dm_log dm_mod sr_mod cdrom ata_generic sg sd_mod usbhid hid ata_piix pata_it821x ohci139 ahci libata scsi_mod floppy ehci_hcd ieee1394 skge e1000 generic uhci_hcd usbcore thermal processor fan [ 254.728467] CPU: 1 [ 254.728468] EIP: 0060:[try_to_del_timer_sync+46/80] Not tainted VLI [ 254.728470] EFLAGS: 00010086 (2.6.20.3-ubuntu1 #1) [ 254.728480] EIP is at try_to_del_timer_sync+0x2e/0x50 [ 254.728484] eax: 00000008 ebx: f7ebbc54 ecx: f7ebbc01 edx: f8dff000 [ 254.728488] esi: 00000001 edi: f7ebbc44 ebp: df1ac380 esp: f4903da0 [ 254.728494] ds: 007b es: 007b ss: 0068 [ 254.728497] Process dmraid (pid: 6165, ti=f4902000 task=f43ce030 task.ti=f4902000) [ 254.728500] Stack: 00000282 f7ebbc54 00000000 c01301fe f7ebbc00 f8de4b3d 00000000 df1ac380 [ 254.728509] df1ac380 f8ddf18b f89c2f59 df1ac280 ffffffea f89c2502 00000000 df1ac280 [ 254.728522] f8df2000 f89c5ac7 f4903e24 fffffff4 f8df2000 00000006 f4903e24 f89c6480 [ 254.728531] Call Trace: [ 254.728545] [del_timer_sync+14/32] del_timer_sync+0xe/0x20 [ 254.728554] [<f8de4b3d>] wake_do_raid_delayed+0x1d/0x60 [dm_raid4_5] [ 254.728575] [<f8ddf18b>] rh_start_recovery+0x2b/0x30 [dm_region_hash] [ 254.728588] [<f89c2f59>] dm_table_resume_targets+0x69/0x80 [dm_mod] [ 254.728615] [<f89c2502>] dm_resume+0x82/0x100 [dm_mod] [ 254.728644] [<f89c5ac7>] dev_suspend+0x137/0x1b0 [dm_mod] [ 254.728679] [<f89c6480>] ctl_ioctl+0x220/0x290 [dm_mod] [ 254.728701] [__alloc_pages+79/832] __alloc_pages+0x4f/0x340 [ 254.728718] [mntput_no_expire+36/160] mntput_no_expire+0x24/0xa0 [ 254.728730] [<f89c5990>] dev_suspend+0x0/0x1b0 [dm_mod] [ 254.728989] [do_ioctl+120/144] do_ioctl+0x78/0x90 [ 254.729014] [vfs_ioctl+92/672] vfs_ioctl+0x5c/0x2a0 [ 254.729040] [sys_ioctl+114/144] sys_ioctl+0x72/0x90 [ 254.729061] [sysenter_past_esp+105/169] sysenter_past_esp+0x69/0xa9 [ 254.729128] ======================= [ 254.729131] Code: ff ff ff 53 89 c3 83 ec 04 89 e2 e8 9d ff ff ff 3b 58 04 89 c1 74 23 8b 03 31 f6 85 c0 74 1b 8b 13 66 be 01 00 8b 43 04 89 42 04 <89> 10 c7 43 04 00 02 20 00 c7 03 00 00 00 00 8b 14 24 89 c8 e8 [ 254.729181] EIP: [try_to_del_timer_sync+46/80] try_to_del_timer_sync+0x2e/0x50 SS:ESP 0068:f4903da0 I hope that i've provided all necessary information for pinning this down, if not, please let me know.
