CentOS 5 :: 5.3 In VMWare ESX - Device-mapper: Dm-raid45: Initialized V0.2429 Waiting For Driver Initialization
Apr 2, 2009
I run many 5.2 virtual machines inside of VMWare ESX3.5 I've updated a couple of test VMs from 5.2 to 5.3. The thing that stands out is that during boot time, the sequence gets to this stage:
device-mapper: dm-raid45: intialized v0.2429 Waiting for driver initialization.
Here it takes about 3 times longer than the previous Centos 5.2 (about 9 seconds instead of 3). Whereas inside a physical box the wait in 5.3 is the same as it was in 5.2

I have a question about the CentOS boot process. During boot, following the initialization of the software RAID drivers, I get the message "Waiting for driver initialization", and the boot process hangs for about 20 seconds. It's not a big deal because I don't have to reboot often, but I'd like to know - is there a way to disable the functionality that causes this, whatever that is?

I am trying to prevent the dm_mod and friends from loading during install.I am installing by PXE boot with NFS and kickstart files over http. This works fine for other machines.Ok, I have a Dell PowerEdge 2900 III with 8gig ram, PERC 6/i raid controller.The raid has 8 1TB drives in it, so the total size of the device is >2TB.There is also an SATA drive, which is NOT on the raid controller.
The problem is, I want to install CentOS on the SATA drive. The SATA drive comes up as a device-mapper drive, with a big crazy device name.This is ok, but the problem is, when the system goes to boot, it just says 'missing operating system'.I can't boot from the raid because it is large enough to require a GPT partition, and CentOS says it can't boot from a GPT partition.The SATA drive would work FINE if I could just prevent the damn device mapper from loading, so that I could install on the SATA drive in ordinary SATA mode.
I have tried re-squashing the stage2.img with /etc/modprobe.conf with alias dm_mod off and such, no luck.I also tried adding an /etc/modprobe.d/blacklist file, that did not work either.I also tried putting blacklist= dm_mod in the kickstart file, but that seems to be a fedora-only option and it kills my install. any ideas on preventing the dm_mod et. al. from loading at install time??

Trying to do a yum update to get everything to latest, towards the end it says this:
[Code]...
how to get around this? I tried yum clean all, then yum update, again but it did the same. I had other deps missing on other servers but yum clean all fixed them -- can't find anyone else who's had this specific issue either, nor an rpm called 'device-mapper-event' or the other things that are missing - am kinda stuck!

I'm running CentOS 5.2 on an ASUS M2NPV-VM motherboard. This motherboard includes an NVIDIA nForce 430 built-in Gigabit MAC (network interface). I've also installed a second PCI network interface card (NC100 Network Everywhere Fast Ethernet 10/100). The PCI-based card was configured as eth0, while the built-in NIC was configured as eth1. The machine is used as my firewall/router, so eth0 is my internal interface, while eth1 is my external interface. I've had some intermittent problems with the built-in (eth1) NIC. When booting the machine and it attempts to bring up the interface, I get the following message: forcedeth device eth1 does not seem to be present, delaying initialization From that time forward, there is no eth1, and so no external network, etc. If I try running /etc/sysconfig/network-scripts/ifup eth1 (from that directory), it results in the same error.
Originally, I was getting this error when installing the operating system on the machine. At that time, I was using a 75' ethernet cable (as I was working on the machine in my office, and the external ethernet jack was in another part of the house). As soon as I moved the machine to its permanent location (which is within 2 feet of the ethernet jack), the problem went away. However, I just updated the kernel (via yum) from 2.6.18-92.1.22.el5 to 2.6.18-128.1.6.el5, and now it fails 9 out of 10 times. I'm not even sure what I can do to debug this. I'm assuming there is some kind of timing problem with the initialization. Is there a configuration parameter I can set to allow more time for the initialization to do what it needs to do, to prevent this error?

Ethernet card works, but Wireless card activation fails at bootup time. It also fails if I try it again from the Network Configuration UI.
I have provided some output I got from initial exploration.
I upgraded to a recent version of the 2.6 kernel.
uname -a: Linux localhost.localdomain 2.6.28.7 #1 SMP Sat Mar 14 19:04:11 PDT 2009 i686 i686 i386 GNU/Linux
I have installed the correct firmware hopefully.
cd /lib/firmware ls
Output is:
I do have the bcm* files for firmware.
output of lspci is:
Last two lines show the that Wireless card BCM4312 is visible.

Recently, I created a device sc0 through device mapper. The divice could be found in /dev/mapper/sc0. My problem is that the device doesn't exist in /dev/partitions which will block my following test.BTW, I found dm-0 in /dev/partitions. Is it the same as /dev/mapper/sc0? But the device /dev/dm-0 doesn't exist!

Dell PowerEdge R610 with QLogic HBA card connected to HP EVA6000 SAN through a pair of switches.When I present space to the server, device mapper doesn't see it unless I restart the multipathd service. Same thing with unpresenting - the /dev/mapper/mpatha does not go away unless I restart multipathd.Here's what it looks like in 'multipath -ll' before and after I unpresent the LUN (without restarting multipathd)...

Slackware 13 Kernel 2.6.29.6 have three hard drives. Root is on own drive sda1. sdb and sdc are raid via mdadm with two partitions. one for /home raid0 md0 one for swap raid1 md1. md0 is encrypted vi cryptsetup. md1 is encrypted vi fstab. everything boots fine and is accessible. However, /dev/mapper/* shows sda1 as block device connected to the raid md0. swap crypted device is correct in /dev/mapper/*. fstab is set correctly. problem seems to be with initrd. I would like the correct device in /dev/mapper so that I can access drive info; size, available space, etc. now info shows only sda1 info

I have a linux machine, attached to a fibre channel SAN.
We're in the testing phases and we're attempting to get all of the bugs worked out before this goes live.
If i have my host streaming data to the storage device on the san (or from the device on the san) and simulate a path failure (by shutting down one of the host's ports on the FC switch), multipath does not pick up on another path until about 45 seconds have passed.
I can verify this by watching the statistic graph (which updates once per second) on the storage system.
I see iops running along rather nicely, and then they drop to 0 for 45 seconds, then pick right up to normal again.
This is a RehHat EL 5.5 system, with qlogic HBA's.
Am i being too picky? I'd expect multipath to recover in under 30 seconds, so as to not alarm host applications running on the linux host... 45 seconds seems like a long time to wait for a disk operation to complete.
Any tips on tuning Multipath, or the qlogic card? As it is, i've got the following options in my modprobe.conf.
alias scsi_hostadapter2 qla2xxx
Code:
My multipath.conf looks like:

I'm having some difficulities with truecrypt and cannot figure out what's wrong since this is my first attempt to create hidden encrypted partition. I'm using ubuntu 9.10 64b with latest 6.3a truecrypt. After using truecrypt gui (just command truecrypt) I've tried: create volume-->create volumne within a partition/drive-->hidden trucrypt volume --> select some /dev/sdX by my choice --> select aes & sha512 --> password --> and format it.
when formating finished message "wrong ss, swith or wrong superblock of /dev/loop0" appeared. I've got no idea what could I do with it neither know whats program trying to do! Ok formating's done, then if you're trying to mount that partition then I would expect prompt for password, but that did not happen ...
EDIT: sudo mount /dev/loop0 /media/tmp/ also complaint about wrong superblock, but that does not ring any bell since i've got no idea what /dev/loop0 is or is for...
EDIT2: I've tried another approach also:
sudo truecrypt -t -c
sudo truecrypt -t /dev/sda3 --filesystem=none
but the first command finished creating 100G drive in 1 sec (nonsense) and latter one prints:
Error: device-mapper: reload ioctl failed: Invalid argument
Command failed

Anyone know how device-mapper works, or can someone point me to any docco (other than the man page)?
Couple years ago I wrote a TrueCrypt wrapper script for use on Puppy Linux, and am reworking it for Ubuntu. Puppy sometimes didn't have the 'dmsetup' device-mapper utility available, but TrueCrypt still works without this when the '-m nokernelcrypto' option is used.
My script notices when dmsetup is available and skips this option. When the TC volume gets mounted (somehow using dmsetup), the Desktop icon is labled with the leaf name of the /media/mount_point -- so far, so good.
However, if I force the script to add the no-kernel-crypto option, and the TC volume is mounted without using dmsetup, the Desktop icon ls labled with the size of the volume. Say what?
Running df shows the difference between the two mounts is whether /dev/mapper is used. So *how is* dmsetup making this happen? The manpage isn't much help. Is it just the 'rename' sub-command? I am unable to find any details about this mechanism.

I have swapped out four known working, different bran network cards. Each one I get the same error as in the subject. If I boot to a Live CD such as CentOs 5.3 LiveCD both Nics are given an IP. This seems to only be happening with my CentOs 5.3 server install.I noticed the CentOS Live CD the Nics were reversed from eth0 to eth1 and eth1 to eth0.
At the moment as of the output of the commands, I am running two identical Nics, since the first one has always worked. I have previously used an rtl8139, 3com c3905-TX, onboard Rhine III based (now disabled) Here are steps I have done to try and figure this out:
Quote:
[root@centos ~]# lspci | grep -i eth
00:0a.0 Ethernet controller: VIA Technologies, Inc. VT6105/VT6106S [Rhine-III] (rev 86)
00:0e.0 Ethernet controller: VIA Technologies, Inc. VT6105/VT6106S [Rhine-III] (rev 86)
Quote:
[root@centos ~]# cat /var/log/dmesg | grep -i eth
eth0: VIA Rhine III at 0xee800000, 00:1b:11:bb:17:7d, IRQ 177.
eth0: MII PHY found at address 1, status 0x786d advertising 05e1 Link 45e1.
[code]....
I went through the system-config-network-tui. I copied /etc/sysconfig/network-scripts/ifcfg-eth1 to the ifcfg-eth0 and edited for sanity. and as stated earlier, have swapped out four different nics for eth0, and booted to two different LiveCD's. Both LiveCD's work fine.

I am using CentOS 5.2. I am installing from disc on a machine with Intel Embedded Server Raid Technology. It has two 500 GB SATA drives. During the initial boot process, it sees that these two devices exist. However, after getting into the screen to partition and configure RAID, it just shows this:
Drive /dev/mapper/ddf1_MegaSR R! #0 (475879 MB) (Model: Linux device-mapper)
I want to do a RAID1 so that the disks are mirrored. However, I would expect to see both drives listed. I can select RAID to create RAID partitions, but I think I need to be able to see both drives in order to do this correctly.

I am trying to setup a H/W RAID-1 matrix but I am unsuccessful. I am trying to get partitions installed as /dev/md0, /dev/md1 but it keeps going for /dev/mapper/isw...The reason is that I have R1Soft backup and it needs to hook the partitions as seen in /proc/partitions from /dev not /dev/mapper/isw. I have tried to boot the installation with various options but nothing!

Unfortunately I've had no luck with using the default intel driver. It's strange really, you can see the gnome screen for a split second then it turns the display off like it's activating the external monitor or something. If I change the driver to vesa everything is fine.

2 weeks ago, my power supply blew, during close-down. My system is a SUSE Linux 10.1 and openSUSE 11.1 dual boot with WInXP (for those family things). After replacing the power supply my system had no root partition, or loader. It said something like "Invalid Partition table". Grub had gone! So following swerdna's "How to Boot into openSUSE" tutorial I used the openSuse 11.1 install CD rescue option to get to the command prompt, su'd, went to grub and followed the stated commands. So far so good.
However the new grub entry openSUSE (Failsafe) has a problem. It starts to boot in the usual way, but I note fatal Module errors in the boot log relating to sata_nv not found, ide_pci_generic not found etc, and Fatal error inserting edd (/lib/modules/2.6.27.39-0.2-default/kernel/driver/firmware/edd.ko): no such device but uses udev as boot source until Waiting for device /dev/disk/by-id/ataST3120827AS-4M60PX7V-part6...... and then it exits to /bin/sh.

I installed ubuntu on my MacBook Pro, and now I get the infamous "still waiting for root device" when booting mac os x. I couldn't find any solutions that worked (macbook pros don't have a BIOS, or any drives that are easily removable). Anyway, so I have ubuntu working, and I need some files from OS X before I would consider reinstalling, etc. So I mounted the drive, went to users, etc. and it says that "I don't have the permissions necessary to view the contents of ****".
I did chmod 777 /media/os x/Users/* but that led to "Could not access: No such file or directory" (there's a space between os and x, I think it counts it as two commands or something and I can't rename the drive). Any way to give myself the permissions to access my files, or maybe just to copy over the whole hard drive to my main computer, or maybe somehow solve the "still waiting for root device".

this is my first setup of ubuntu. And I�m quite familar to Linux allthoug it�s been a while since my last setup. Anyway, my system is brand new and consist of the following parts:
AMD Athlon X2 240e on MSI 880GMA-E45 (SB850)
4GB RAM (DDR3)
All drives connected by SATA using onboard SB850 ordered by:
1 LG BluRay optical drive
2 WD Caviar Green WD10EARS 1TB
3 WD Caviar Green WD20EARS 2TB
4 WD Caviar Green WD20EARS 2TB
5 WD Caviar Green WD20EARS 2TB
6 WD Caviar Green WD15EARS 1,5TB
I set the SATA controller to AHCI because I want to set up a software raid (level 5) on the three 2TB-disks. The first disk (1TB) should be the ubuntu boot disk (no raid). The last one (1,5TB) is currently not connected - it will be added later. First I struggled booting the ubuntu server 10.10-CD (x64) from the bluray drive - after succesfull starting the setup procedure it told me that it cannot access the drive. It seems that drivers are missing. No problem - I connected an usb dvd drive to the system and gave it a try.
The boot order was set to usb-dvd, then bluray, then the first harddisk (1TB). Setup seems to run fine using the usb dvd drive. I�ve chosen the first disk (shown as /dev/sda) for the installation. It was automatically configured as one big root-partition and a small swap-partition. Grub was installed on the MBR of the first disk. But after restart GRUB tells me "Gave up waiting for root device" and "ALERT! /dev/disk/by-uuid/whatever does not exist. Dropping to a shell!". Obviously the boot loader cannot find (or access) the volume containing the kernel.
I made some research and found some other people complaining about some mixup of hdaX and sdaX devices on SATA devices - but these statements where from 2007. Another point is that the USB optical drive is my boot device while the installation runs, but not afterwards - does this matter? I also tried installing Ubuntu server 10.04, but is behaves the same. Please keep in mind that the goal is to have ubunto server 64bit running on this system - that�s it. No dual boot is needed. And there is no data on any disk that should be taken care. It�s a very new system. Where should I start to fix this issue? What�s wrong with the current linux boot loader using SATA disks connected to SB850 SATA controller?

I did an installation of Ubuntu 8.1 on my laptop. I ran the live CD first to check that everything was ok and got no problems. But when I try to boot I get this error:
Boot from (hd0,0) ext3 e194- long number
Gave up waiting for root device.
Alert /dev/disk/by-vvid/e194- long number
I tried a different hard drive with the same results. So I installed XP and everything worked fine. This makes me believe that all of the hardware is ok and I have some config screwy.

I've read hundreds of threads on this problem but they seem to be intermittent and the resolution has been using a different kernel version.
I'm using the latest kernel but I still have this problem
Running Logical Volume Manager gui and attempting to extend the volume results in the same error.

recently attempted to upgrade to Lucid Lynx but it's not booting up. it just shows "Gave up waiting for root device" and drops to BusyBox. waiting doesn't do anything. i see the GRUB options but none of the 3 10.04 LTS's boot up. i've read a number of threads but i don't think my Ubuntu drive is being read. i say this 'cause cat/proc/partitions doesn't list my Ubuntu drive/partition. Also when booting up in the Live CD, GParted only lists the Windows partition. neither does sudo fdisk -l.

The case is that I've got 2 harddisks. On the one windows xp(slave) - and on the other one ubuntu (master). During the boot I get these errors...
"Gave up waiting for boot device"
"Boot args(cat /proc/cmdline)"
"Missing modules (cat /proc/modules; 1s , dev)"
"/dev/disk/by-uuid/f96603ce - does not exist"
These problems occured because of this:
After using ubuntu I tried to reset my bios, because else it couldn't have found the disk with xp. And I didn't disconnect the disk with xp while resetting the bios. And now the system can't find the disk with xp any more when booting. Is there a way to finding the disk..? And I'm in doubt about IF I've resetted the bios at all. I miss a manual for PCCHIPS M851. May be it can take 20 minutes for the bios to be resetted? The shop where I bought the motherboard doesn't exist any more... and don't know the manufacturer. Could I damage the motherboard if I tried rebooting lots of times to get it work?
