May 13, 201115 yr I've tried this a number of times for both 4.7 and the latest 5.0 beta with no success. I've very meticulously followed the wiki, and emhttp always segfaults when I get to that step in either 4.7 or 5.0 b6a. I read a post here with the same errors, but didn't find anything that applied to my situation that I could tell. emhttp: unRAID System Management Utility version 5.0-beta6a emhttp: Copyright (C) 2005-2011, Lime Technology, LLC emhttp: Pro key detected, GUID: 0781-5406-4857-411DC342805E emhttp: shcmd (1): udevadm settle emhttp: Device inventory: emhttp: Maxtor_6L300R0_L60MMHPH (sda) 293057320 emhttp: shcmd (2): modprobe md-mod super=/boot/config/super.dat slots=21 2>&1 |logger logger: FATAL: Error inserting md_mod (/lib/modules/2.6.36.2-unRAID/kernel/drivers/md/md-mod.ko): Unknown symbol in module, or unknown parameter (see dmesg) emhttp: diskId.0 not found kernel: emhttp[32449]: segfault at 0 ip 08050579 sp bf863f60 error 4 in emhttp[8048000+15000] strace snippet: (entire strace.txt attached) stat64("/proc/mdcmd", 0xbf928970) = -1 ENOENT (No such file or directory) time(NULL) = 1305312299 send(4, "<14>May 13 11:44:59 emhttp: diskI"..., 46, MSG_NOSIGNAL) = 46 --- SIGSEGV (Segmentation fault) @ 0 (0) --- I've reviewed the make compile log and no errors there.

May 18, 201115 yr Author http://lime-technology.com/wiki/index.php?title=Installing_unRAID_5.0_on_a_full_Slackware_Distro Thank you for the reply!!! :-)
May 18, 201115 yr Author As far as I can tell everything went well there. I've attached the compile log. On make modules_install the md module showed up as DEPMOD which was different from the rest, but I assumed that was OK--is it? Thanks again for your help! make.log.txt
May 18, 201115 yr Author Yes, /boot/config/super.dat exists and is the file from the flash drive. I appreciate you sticking with me on this so much! Tony

May 19, 201115 yr Try "modprobe md-mod" w/o a command line and see what you get back.... check syslog and dmesg.
May 19, 201115 yr Author nothing came back in either /var/log/syslog or /var/log/dmesg or /var/log/messages after running #modprobe md-mod At the moment all my drives and the flash are installed. /var/log/messages shows the following when I try to run emhttp -p 88 emhttp: unRAID System Management Utility version 5.0-beta6a emhttp: Copyright (C) 2005-2011, Lime Technology, LLC emhttp: Pro key detected, GUID: 0781-5406-4857-41<******> emhttp: shcmd (1): udevadm settle emhttp: Device inventory: emhttp: Maxtor_6L300R0_L60MMHPH (sda) 293057320 emhttp: WDC_WD2001FASS-00U0B0_WD-WMAUR0194407 (sdc) 1953514552 emhttp: WDC_WD6400AAKS-00A7B0_WD-WCASY0013739 (sdf) 625131832 emhttp: WDC_WD1001FALS-00K1B0_WD-WMATV0782348 (sdd) 976762552 emhttp: WDC_WD2001FASS-00W2B0_WD-WMAY00649474 (sde) 1953514552 emhttp: SAMSUNG_HD753LJ_S13UJ1CQ600821 (sdh) 732574552 emhttp: WDC_WD2001FASS-00U0B0_WD-WMAUR0193889 (sdg) 1953514552 emhttp: MD01200-BJDW_MW0WCANM1163371 (sdj) 120627328 emhttp: WDC_WD6400AAKS-00A7B0_WD-WCASY0015595 (sdi) 625131832 emhttp: shcmd (2): modprobe md-mod super=/boot/config/super.dat slots=21 2>&1 |logger emhttp: diskId.0 not found kernel: emhttp[1539]: segfault at 0 ip 08050579 sp bfb56890 error 4 in emhttp[8048000+15000] Booting off the flash works.

May 19, 201115 yr Do you see a /proc/mdcmd ? If not, that means your kernel was not properly built and unRAID didnt get implemented into it. In the 5.06a guide, I had to add the following in my make menuconfig: Device Drivers -> Multiple Device Support -> (*) Multiple devices driver support (unRAID) and <M> RAID support Watch your build and make sure unRAID gets implemented. You should see something like this compile: drivers/md.c And something about unRAID later...
May 19, 201115 yr Author Wow. That was the clue I was looking for! My menuconfig did not have: Device Drivers -> Multiple Device Support -> (*) Multiple devices driver support (unRAID) On further investigation I found that inexplicably, WinSCP put the drivers folder inside the drivers folder (/usr/src/linux/drivers/drivers/md) I'm really puzzling over that. I'm not sure what its reason for rewriting the paths like that was--how or why it did that. (It's generally well-behaved for me). Anyway, after making sure the md folder went where I actually told it to go, I now have the unRaid MD listed in menuconfig. Recompiled the kernel. Rebooted. And... emHTTP starts! Wow thanks again! I sooooo appreciate your help! Ran mkmbr on my drives to get my files back and we're in business! I am sooo happy. Thank you again so much for helping me out on this. Tony
May 19, 201115 yr Glad I was of help. I had the exact same problem and it took a few days (and a few forum posts) for me to get it right. I am not sure if this is something that affects everyone or not. If it does, adding Device Drivers -> Multiple Device Support -> (*) Multiple devices driver support (unRAID) and <M> RAID support should definitely be added to the Wiki. Can anyone more versed on the subject comment?
