I'm running CentOS 5.5 with a hardware Areca controller (Raid 10). I initially installed a machine and rsynced the file system to a third machine; I'm then pulling in the file system to new machines and updating grub with a script to make it bootable.
I've done this before with other machines (no raid sets) but with these machines I'm running into errors code...
I face a problem with my server after i rebooted it i got a message on start up tell me that " Unable to access resume device (label=swap-sdb3) " and the system doesn't startup
the error message exactly is
Unable to access resume device (lable=swap-sdb3) Creating root device. Mounting root filesystem. [ 3.305354] EXT-fs (md1) : error : unable to read superplock mount: error mounting /dev/root on sysroot as ext3 : invalid argument
I'm trying to move an existing FC10 install (created by someone else) from a 160GB WD1600AAJS SATA disk to a 160GB WD1600AAJB PATA disk (cursed trend of horizontally mounting SATA connectors at the end of the motherboard means the latest rev mobo doesn't fit in our enclosure!). I've used DD to copy the disk image from one to the other, but when attempting to boot, I get the following error:
Code:
Unable to access resume device (UUID=946f216f-0c24-4b02-a996-f42059970de7) mount: error mounting /dev/root on /sysroot as ext3: no such file or directory
That particular UUID maps to sda2, which is the swap partition. Interestingly, both the SATA and PATA disk come up as /dev/sda on the motherboard. I kind of grok that the UUIDs are substitutes for directly naming the disks, and that they're referred to in fstab, initrd-2.6.27.12-170.2.5.fc10.i686.img, and in /dev/disk/by-* I'm guessing the problem is that the GUIDs (at least the one for swap) are no longer the same. How are they assigned to the partitions during boot?
I tried doing
Code:
swapoff -a mkswap /dev/sda2 swapon -a
and put that new GUID in fstab and into initrd-* (using some steps I found elsewhere on how to gunzip/rezip it).At that point, I get a kernel panic on boot
Code:
Kernel panic - not syncing: CFS: Unable to mount root fs on unknown-block(0,0)
So I'm guessing that the other UUUDs have changed as well and I need to update them. How would I figure out what they are? I suppose I could change the references to /dev/sda*, but I didn't build this original image and I'm thinking whoever did had a good reason to go with UUIDs.
I have FC6 system with kernel 2.6.22.14-72.fc6 When I rebooted my system, I got error message "unable to access resume device (LABEL=SWAP-sda8) then it went to fsck automatically to all the partition and then stop (failed)
I already know "what" my problem is, however I am having difficulty fixing it. I recently upgraded our companies server to a HP ML150; decided to upgrade to FC10 hoping it would go smooth and it is not. It does not detect the SATA drives after the installation.
I get.
"Volume Group "VOLGroup00" not found Unable to access resume device (/dev/VolGroup00/LogVol01 mount: error mounting /dev/root on /sysroot as ext3: No such file or directory
I know the problem is that my SATA is not enabled in the kernel or grub, but I don't know how to fix this. My internet searches are coming up a little short and LIVE discs are not working so I am having trouble figuring this out.
Dual PII 400, 512Mb with a Promise SuperTrak 100 IDE Array Controller. At present I have only one drive on the controller, configured for 1 JBOD array. I install FC9 with no problem. New partition is created and formatted, Grub is installed, and then... Grub is found and booted, but then I get:
Reading all physical volumes. This may take a while... No volume groups found Volume group "VolGroup00" not found Unable to access resume device (/dev/VolGroup00/LogVol01) mount: could not find filesystem '/dev/root' I can boot in rescue mode, chroot to the installed system. I changed the kernel boot parm "root=/dev/VolGroup00/LogVol00"
When I boot CentOS 5.5, I receive the message:Unable to access resume device ( UUID = some UUID etc. )How do I find out what actual device to which this UUID refers ? It does not appear to be a block device since it does not show when I try 'blkid'.To what does "resume device" refer ?
Wanted to restore laptop to Windows 7 and put Ubuntu on another machine. The Laptop is an Acer and the Win 7 disks go into a propitiatory recovery screen. I have 3 choices reload Win 7 to new state, Load Win 7 and put everything in backup or Exit.
I have loaded the Ubuntu 10:10 Live and downloaded ms-sys. The problem is Ubuntu is unable to mount the HDD - not in fstab.
I've installed ubuntu 10.10 yesterday and i went to check something in my MS OS, im choosing "windows 7 loader XYZ"(XYZ reffers to something sda/....) in it comes back to the grub menu, any help please? im searching for hours for a solution and i can't find.
I'm pulling my hair out trying to figure out what is wrong with my Samba share. I have set up a directory /samba to serve up some movies, music, etc, on an Ubuntu 10.04 Server box. For now, I have given that directory 777 permissions, along with the subfolders:
Code: drwxrwxrwx 4 michal michal 4096 2010-06-22 18:02 Apps drwxrwxrwx 3 michal michal 4096 2010-06-22 19:02 Music drwxrwxrwx 3 michal michal 4096 2010-08-14 19:27 Pics drwxrwxrwx 5 michal michal 4096 2010-06-22 19:48 Video This is how my smb.conf file looks like for this particular share:
Code: [share1] comment = share1 browsable = yes path = /samba write list = michal Furthermore, I went ahead and mapped the Samba user to my Linux user account in /etc/samba/smbusers:
Code: michal = "michal" When I try to login from a Windows machine using michal as the username, I can see the folders, but I am unable to create new files on the share. Considering that the file system permissions are liberal on the share directory, I have no clue as to why I'm still getting denied write permission.
I am stepping into Linux world ...and I have chosen CentOS. I have installed CentOS 5.5 on a dedicated IBM server successfully. My server has two network cards. I have configured eth0 for lease line internet connection with a live IP (113.xxx.xxx.xxx) and eth1 for local LAN with a static IP (192.168.0.1).
Now, 1. DHCP is working fine and I can access the server from my Windows XP clients. 2. I can access the server with SSH client PuTTY from home ( with the live IP ) and from the local LAN (with static IP 192.168.0.1) 3. I can access my shared server directory 'public' from my XP clients 4. Internet is working on sever and I have updated the server with yum update.
But, I cannot access internet from my XP clients machines.
I read "The Definitive Guide to CentOS" and tweaked the config files in different ways but it did not help. now after two sleepless nights I am here as my last hope.
I admit, I am not aware of every linux terms and commands, but I am getting into it. code...
I have an external hard drive connected to my router. From Windows I can access it, but from Ubuntu I can see the hard drive, but when I try to access, I'm asked for a password. However my network does not have a password neither the hard drive. What must I do?
I recently installed Deluge 1.2.0 from the following PPA:[URL]I using this on two different Linux computers. One is running Linux Mint 8 and the other is running Ubuntu Netbook Remix 9.10. The first time on either computer when I enable WebUI in the Deluge GUI it works fine. However if I ever disable it in plugins section I am subsequently unable to re-enable it (doesn't appear in the side panel again). Rebooting or reinstalling Deluge seems to have no effect.Is this a bug or am I doing something wrong?
A problem with installing CentOS 5.3 from DVD ... I downloaded the CentOS-5.3-i386-bin-DVD.iso, after recording an image on DVD Start the installation, selecting Installation Method, chose Local CDROM - Message on my screen: "CD Not Found"
One of my colleagues was working on my system (Centos 5.6). He deleted some files from the /tmp directory (he thought he was cleaning up files). Right after that, he rebooted the system. I now can no longer login.
Prior to this, here's what I see following a reboot code...
no matter what I use, I cannot login -- it takes me back to the (none) login: prompt
Any ideas? I know that deleting from the /tmp directory could lead to catastrophic results, but he thinks he only deleted a specific set of files.
I have a LVM snapshot that triggers these kernel errors when any LVM-related commands run:
Jul 6 10:31:38 itmanager kernel: attempt to access beyond end of device Jul 6 10:31:38 itmanager kernel: dm-28: rw=0, want=66156996183394672, limit=25165824
dm-28 is the snapshot volume in device mapper. I think this error is generated because most LVM commands will check the first 4K of various drives and volumes for LVM metadata and labels, but attempts to read any of the first eight sectors (ie: 4K) of this particular snapshot logical volume trigger this error.The most interesting thing is that the snapshot is 25165824 sectors long (12G), but attempts to access the first eight sectors result in an attempt to access sector 66156996183394672!I've obtained an info dump from getinfo.sh disk, and added the output from lvs. You can find the results here:URL.. It's not as if the sectors that back the first 4K of the volume are corrupt, either: the read request never hits any hardware because the read request is attempting to read a non-sensical sector, instead of the correct sector. Perhaps the COW metadata for the snapshot is corrupt?
How do I find the cause of this problem?Is this a critical error that I should file a bug report for?I first noticed this some time after turning the machine on Sunday afternoon.As far as I can tell from the logs, the shutdown the previous evening was normal.I use LVM fairly heavily on this machine, and this is the first time I've ever seen this kind of problem..I've worked around the problem by copying the first eight sectors from the Origin volume, and the rest from the Snapshot volume, to a new normal logical volume.However, I'm still concerned about how this error occurred in the first place.
I'm experiencing some strange issues with a C5 installation on a Dell server with a QLA2460 HBA. When it boots up, I got a lot of these messages on dmesg:
I am unable to boot my server and it is erroring with the message "Kernel panic - not syncing: Attempted to kill init!". Here are the details:
I have a brand new Dell PowerEdge T110 server with Quad-Core Xeon CPU and 2GB 1333MHz RAM. I have installed a hard disk (SATA, 7.2rpm) on this machine that I removed from another Dell PowerEdge T100 server with Dual-Core Xeon CPU that was running software RAID 1.
Now when I boot the new T110 server, it displays the following error messages code...
I am running CentOs v5.5 x86-64. If I put the hard disk back into T100, it boots fine. I do not know why it is not working with T110 server.
I've just started using OpenSuse 11.2 KDE. I have KDE4.4 installed. I had this issue with KDE 3.4 as well. My HP Multimedia DV3065 laptop is encountering an issue with suspend/restore. After restoring, the mouse is frozen. I have already tried a few things.
1. Dropping to init 1 and then back up to init 5 did not provide a temporary fix. So this is probably hardware related in some sense (kernel?) 2. I tried a grub option (cant remember what it is now). i8500-reset something like that. It made no difference. 3. I tried modifying my 99ZGrub file per another posts suggested solution. That actually locked up my laptop and I could not reboot (even after a cold boot). I pulled the battery and let it sit for a bit and it booted again
So I have several issues.. 1. I would like suspend to restore my mouse. 2. I have not figured out how to program my Sleep button to Sleep. My menu bar icon has Log Out / Restart / Turn Off. The ALT+F1 menu tab Leave has those plus Sleep and Hibernate.
I recently installed 10.10 Maverick on a lenovo S12, and I've been having problems with the wireless connection. First I installed the Broadcom B43 driver. This driver seems to work well except upon resume, I'm no longer connected, and wireless is disabled, and the 'enable wireless' is grayed out and I can't seem to find a way to enable it besides a restart.
I tried what is suggested in this post: [url]
Namely:
Code:
Put:
Code:
This doesn't seem to have any effect
I also tried the Broadcom STA driver. This was only better in that after resuming it tried to reconnect, but never managed to.
Currently I only only resume from suspension by pressing the power button. I learned that by editing /proc/acpi/wakeup one can enable resuming from other devices. But how to figure out which is for which device? Here is my /proc/acpi/wakeup file:
Code: DeviceS-state Status Sysfs node PCE2 S4*disabled pci:0000:00:02.0
I was trying to get this feature: wake up my htpc from s3 with my remote control and the solution is to modify /proc/acpi/wakeup and a descriptor in /sys. Here are the details: I'm using a Microsoft IR receiver for MCE remote that appears as dev 2 of bus 2 in lsusb
root@htpc:~# lsusb Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 0471:0815 Philips (or NXP) eHome Infrared Receiver Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 006: ID 045e:0714 Microsoft Corp.

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub....
That's USB0 I have to enabled, why not usb 1 or 2 (bus 2 in lsusb)? Moreover why are all the disabled/enabled preceded with a star and S4 and not S3 mentioned? Nevertheless that wasn't enough to get it work. I looked in gconf-editor in apps/gnome-power-manager/general but I have no can-suspend or something similar... (I'm running on 10.10, with 10.04 I could suspend only once, afterwards the computer didn't go to suspend, just black screen then login screen). So I looked in /sys/ and found that 'cat /sys/bus/usb/devices/2-1/power/wakeup' (notice the 2.1 as bus 2 device 2 (0,1,...) gave 'disabled' so a echo enabled > /sys/bus/usb/devices/2-1/power/wakeup and now I can wake-up with the remote when I want.
What I don't understand: Why USB0 in /proc/acpi/wakeup ? Why have to change in /proc and /sys ? Is it possible to automate this to get it work even if I change the usb port the receiver is plugged in ?
I am having trouble with a rather peculiar timeout during resume from suspension and I was wondering if any of you have encountered the error or might have some leads as to what causes the problem.I am using Gentoo Linux with TuxOnIce patched kernel. While both hibernation and suspension works as advertised, there is a rather irritating timeout while trying to resume from suspension. Each and every time it takes about 60s for notebook to resume back to X session again, no matter what the conditions are (i.e. USB deviced plugged in, etc.)
