Fedora Servers :: FC10 Kernel Panic - Stale NFS File Handle
Mar 20, 2009
A FC10 server hung and had to be power-cycled. I suspect it hung because of an nfs mount timeout.
Now it does not boot. The error is libc.so.6 not found. Kernel panic. Attempting to kill init.
Booting under rescue:
ls: cannot access libc-2.8.so: Stale NFS file handle
Is there a way to reboot to a clean state? There must be some NFS cache file.
I also tried to cp rescueCD:/lib64/libc-2.8.so to the old lib64 dir, but get the same "Stale NFS file handle" message.

I've got a problem while accessing the /etc/sysconfig/network-scripts/ifcfg-wlan0 file, CLI's throwing: "Stale File Handle" - there's no access to this file. Problem is the same regardless wlan0 interface is up or down.

I currently have a home network setup so that my main machine shares it's external hard-drive via NFS. This has been working perfectly for months, however I just got a new laptop, installed openSuse 11.3 x64 and set everything up. Now there is two folders on the external network mount that won't let me do anything and always just return Networking: Stale NFS File Handle. The system still works fine under my old openSUSE 11.2 x86 laptop. I have tried unmounting the drive from the laptop, restarting the NFS client, and restarting the NFS server on the main machine. None of these have made a difference.
It is only these two folders that are effected. Everything else works just fine.

I did a backup of the ssd on my eeepc using the following command from a Linux Mint on a USB key:
dd if=/dev/sda1 of=/media/disk/eeepc_save/SYSTEM/system.bck
(/media/disk in an external USB disk)
I deleted the ext2 partition using GPartEd on live USB key and created it back. I rebooted Linux Mint and restored the filesystem using the opposite command :
dd if=/media/disk/eeepc_save/SYSTEM/system.bck of=/dev/sda1
I mounted /dev/sda1 and when I "ls" the root directory, I get several "NFS stale file handle" messages concerning directories (/dev and other). I tried "e2fsck -y", had a bundle of corrections that resulted in the deletion of the directories. I don't use NFS. I did the same for the user filesystem and had no problem (it's an ext3 partition). The two filesystems are the ones that came with the original Xandros installed on my eeepc and that were mounted with union-fs.

I've got something showing up in my /mnt directory that I can't figure out how to get rid of. If I try to delete it, I get, "ERROR: Stale NFS file handle". I've tried googling it, but the only solution I can find is "remount and then unmount your NFS server". The trouble is that I don't have any NFS servers - it was a mountpoint for a squashfs file. Trying to remount the squashfile just gives the same error message. My best guess for how it was created is that maybe the file was deleted while mounted. Surely there is a way I can get rid of it? It stuffs up my system by e.g. preventing find from working. I'm running Puppy Linux 4.1.1, although I suspect that is irrelevant.

When using rsync to copy from one NFS mounted filesystem to another mounted NFS, rsync displays "stale NFS file handle" while attempting to issue a chmod after each file is copied. The files appear to be written successfully but the owner and group show up as "99." The source file system is mount USB ext3 drive and the target is a Buffalo TeraStation TS-XL/R5.

I have a 20TB filesystem, xfs formatted. The filesystem has been mounted with the inode64 option, and I now need to NFS export it. NFS doesn't like the inode64 option at all. The NFS clients cannot access any of the directories with inode numbers exceeding the 32bit limit. They get the "Stale NFS file handle" message. I have tried to attach the filesystem to a RHEL5.3 system, and after turning on the no_subtree_check option in /etc/exports on the server, it all works fine. No changes were needed on the clients.
The problem is that I need to get this to work on a RHEL4.4 system. Unfortunately I cannot do any test on that system yet, I then did a quick test on a RHEL4.3 system... and it didn't work. Even using the no_subtree_check option was on any help. I am afraid that this will not work on the RHEL4.4 system either. How to get the inode64 xfs filesystem NFS exported on a 2.6.9 kernel?

I get this error which means I cant visit websites. I cant rm, cp, mv, vi, ... this file. How do I regain the ability to browse the internet? Is there a way I can create a /etc/resolv.conf2 and have my system use that instead?

When I run lilo (/sbin/lilo), it messes up my /boot partition. Next time I try to mount it after running lilo, I get an error: "mount: Stale NFS file handle" (I define -t ext2). My /boot partition is ext2, mounted locally, and not nfs. Then I do fsck /dev/sda1, and I get several: Free blocks count wrong for group #0 (7665, counted=5063). Fix<y>? I say yes to all and it works normally afterwards. This happens only after I run lilo. Lilo is installed in MBR.
Here is relevant configuration:
Code:
root@darwin:/home/cabrilo# cat /etc/lilo.conf
append=" vt.default_utf8=0"
boot = /dev/sda
bitmap = /boot/slack.bmp
bmp-colors = 255,0,255,0,255,0
bmp-table = 60,6,1,16
bmp-timer = 65,27,0,255
prompt
timeout = 30
change-rules
reset
vga = normal
image = /boot/vmlinuz
root = /dev/sda3
label = Linux
read-only
This is my partition table:
Code:
root@darwin:/home/cabrilo# fdisk -l
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

I recently upgraded from FC7 to FC10 (Also, the Kernel from 2.6.22.9 to 2.6.27.19).I did the upgrade through Yum (First installed the fc10 rpms, then did yum upgrade).Now the new Kernel won't boot.These are the options in GRUB for the new Kernel
Code:
root(hd0,1)
kernel /boot/vmlinuz-2.6.27.19-170.2.35.fc10.x86_64 ro root=LABEL=/ rhgb debug

I was following the relatively simple instructions here for setting up a LAMP system. After having installed Apache2-related applications, I ran
# a2enmod expires
# /etc/init.d/apache2 restart
That worked fine. Then, a little later, after having set up a virtual host for my project website, and after installing PHP, MySQL and setting up a Mail Server with Exim, I rebooted and started getting errors when trying to start Apache:
Starting web server: apache2apache2: Syntax error on line 185 of /etc/apache2/apache2.conf: Could not open configuration file /etc/apache2/mods-enabled/expires.load: Stale NFS file handle
Now it seems as if there is nothing I can do with that file:
# rm -f /etc/apache2/mods-enabled/expires.load
rm: cannot remove '/etc/apache2/mods-enabled/expires.load': Stale NFS file handle
# cd /etc/apache2/mods-enabled/
[code]....
Is there anything I can do to refresh the NFS index so that it finds or removes this file? I'd be happy to just get rid of it. At the moment, I can't start Apache or anything because of it.

I have built a new server, now I am trying to restore my db from mysql. I have a backup that is out dated, I was hoping there was a way to copy the files over and have them work on the new installation. I can boot the server with the installation cd using recovery mode, I can get to the hdd and mount a smbfs share from the new server. I have tried to cp the files retaining the permissions and get a permission denied error, but if I copy without retaining the perms they copy just fine and do not work.
I have setup the new server with very close to the same version of all software. I have built a new instance of my service using all of the same users and passwords. I then backed up the new db and moved it over and attempted to copy the old db over. I did not copy it straight to the mysql folder as I did not share that folder out. Any other ideas to get this db recovered? What about getting my old server to run again just long enough to get a mysql dump?

I'm new to ubuntu and I wanted to setup a headless server (Asus Hummingbird, 2GB RAM, Ubuntu Server 11.04). The installation was successful but: After I tried starting my server without any connected monitor, the server did not start -> I run into a kernel panic (if I connect the monitor after a while I can see the messages on the screen, Keyboard lights flash...). What do I have to do to get the machine running without any monitor? My second problem is, that the Network is always powered down on system power down -> no WOL is possible. Is there an easy way of enabling the WOL function? I tried several things from different tutorials but nothing worked...

I am getting a problem when login into FC10. It boots correctly an shows the login screen; then, when typing my user and passwd goes to the desktop and shows a KERNEL FAILURE. At this moment, most of the times the PC is blocked and doesnt works any more. One time has continued working without problems.
After the las failure, my system log has this info:

I just tried to update to kernel 2.6.27.15-170.2.24.fc10 (x86_64) at the suggestion of the gnome update widget, and the process hung. A bunch of other things were updating at the same time, many of which were related to audacity or wine.
I'm not sure just what was being updated, because the option to review which updates are available does not work - when I click on it, nothing happens, but when I take the other choice (install all updates), I take pot luck. It would be nice to be able to choose which programs to update, and to be able to upgrade the kernel independently, but I don't seem to be able to do that at the moment.

just as the title states i need to upgrade my os from fc4 to fc10 first let me say i have no physical access to the box. all i have is root ssh access to it. So i need to know the best way of upgrading that will be safe. before i do the upgrade the server will be backed up so i will not loose any files. if the upgrade fails the data center will reload the os with what i need on it. but i would rather not have to format.

I want to backup my apache website using tar. I want to make sure all the permissions and such stay the same so that if I restore a website, it's ready to go exactly as it had been.I am using the following command and would like to know if there is anything else I should neeed to do?
tar --xattrs cvzf backup.tgz /path-to-webserver-files
Now my other question is since tar doesn't store absolute paths, when I run the restore I have to be in the root directory? In another words if I run the command in a user directory will tar do something retarded like encode the paths as ../path-to-webserver or will it just be path-to-webserver so that when I run the restore from the / folder it will automatically go into the right place?

So my server running FC4 died last night and I decided to go ahead with the long-awaited upgrade to FC10 while I was rebuilding my server. I use my server for a number of things including, but not limited to: router, firewall, web server, mail server... I have a typical configuration process that I have followed since before fedora, and it has worked well for me up through FC4, but my usual config process doesn't work on FC10.
First of all, I don't want SELinux running, I didn't see an option to not install it during the FC10 setup, so how to I properly disable or uninstall it afterwards? Second, I was unable to even configure the server to route traffic from my internal network to the web, here's the process I usually go through for this:
[Code]...
I don't have a static IP from my ISP, so I'm not quite sure how to add the default route. I think I need to do something like "route add default gw xxx.xxx.xxx.xxx eth1" where eth1 is my external NIC, correct?
What else do I need to do to route traffic? I noticed that I wasn't even able to ping my server from the internal network even though they are on the same subnet, my server's internal NIC has an address of 192.168.7.1 and my computer on the network has an address of 192.168.7.2. If I can get this going to I have internet access again at the very least, I can move forward with the web server, email, etc.

I recently setup a file sharing server with FC10 running Samba...
I got it running perfectly and it ran great for a few weeks. I was working on the machine today and tried to reboot it and noticed that it was stuck on FC10's new boot screen. I pressed the esc key and saw that the boot process was stuck on the smb service...
I don't get any errors and the machine doesn't freeze up or anything, it just hangs on the smb service and won't continue with the boot...
Is there anyway that I can get the system to skip the smb service so that I can get into the system? I don't know what's changed or what's causing this sudden hang in the system at boot.
I tried the ubuntu live CD to attempt to go in and edit the /etc/rc5.d scripts to try and skip the smb service start but I am not sure where to look for it...

Recently i've been playing with few variations of linux distros since my Windows XP got infected with something that makes anything flash-player related crash or restart computer even(im saying this because it might be related), reinstall didn't help fix it so i decided to better switch back to Linux world and tried some newest distros. Everything was nice untill..recently some distros after installation gave me kernel-panic or caps lock+scroll lock lights blinking..trouble is Fedora 14 just gave me same stuff after i went maybe 5mins away from keyboard with web browser open then came back to notice..if at first i thought it was wrongly made distribution now i'm bit scared that my PC is dying..i did basic search in google and people say it may be related to hardware beeing too old or drivers but when i use it then i don't encounter this - just when afk. I have almost none experience in Fedora so was just wondering if someone could point me to right direction

The Fedora 11 Live CD was tested on a Dell and it is good. On the HP Pavilion a705w, with an Intel Celeron 2.93HHz w 760MB RAM, the install fails with kernel panic. The cd was burned on the HP.
A colleague suggested that the HP may not be compatible with the kernel. Are there startup settings that I might try to diagnose the panic issue? Perhaps there is a verbose boot up process that pauses so one can take notes?
