I am trying to edit the file shmmax in proc/sys/kernel/. I want to increase the value. I am using vim to edit it. But when I try to write and close the file I get the following error:

I have read that this can be cause by a full disk. I checked with df and have plenty of space available.

I have fedora 14 installed and wish to use/learn kvm. I installed via groupinstall the virtualization group. I see vmx in /proc/cpuinfo. but when I start virt-manager I get a message that kvm is not installed or cannot be leaded into the kernel (to make a long message short). I am at a loss here as to what to do. I run cat /proc/modules and see "kvm 257420 0 - Live 0xffffffffa022a000". also after running modprobe kvm I run [root@fed14 ~]# lsmod | grep -i kvmkvm 257420 0 and see kvm there.
View 3 Replies View RelatedOk here's the problem : I tried to patch the kernel of my Debian server with GrSecurity but when I rebooted I couldn't SSH the server anymore, but my host has a rescue system that lets me SSH the server so I can fix things.
So maybe the kernel patching failed, maybe it's a only a problem with Grub.
I don't really know what to do to fix this. If I messed up the kernel what can I do ? Can I just fix the problem by modifying the grub entries to only boot on the old kernel (I don't even know if it's here anymore, I'm quite the n00b) ?
Well for now I'll just try to mount the partitions (won't let me do "mount: can't find /dev/sda1 in /etc/fstab or /etc/mtab" )
edit : to be clearer my main question is : how can I determine if it's because the kernel is messed up or because the system wouldn't boot properly ?
edit 2 : is there a way to create a log of what happens at boot so I can have an idea about what's wrong ?
I'm looking to edit my grub.cfg file to add the "pci=routeirq" code to the kernel line so I can configure my modem in Ubuntu. I'm happy with assigning a temporary permission to myself over the root file so I don't accidentally alter it later.

Always the same error when booting. After a period of time, (Graphical User Interface) the mouse click no longer operates, also text input isn't possible.
I had no access to the system at all, even crt alt F1 stopped working, also text input was no't possible. so reinstall was the only option. Maybe there is a connection with this two errors.
I've reinstalled Debian 8 several times. Still, both errors stay.
The same happend again (in the GUI) is nothing possible, no txt input, no mouse click), but now I have access to the system, ctr/alt F1 is working.

I do not know if this is really something I should worry about. I am running Debian testing on my laptop (HP Pavillon dv6). Today, the aptitude update---aptitude upgrade gave me a new kernel (2.6.39). However, if I boot with that kernel, I get a warning (do not know if that is the way I should call this) telling me that the machine failed to get the i915 symbols so turbo graphics will be disabled.I have not done any serious test, but at first sight I do not notice any difference performance-wise with respect to the previous kernel. what am I supposed to do to fix this?
View 8 Replies View RelatedI am trying to get my Debian system running. I have an older Dell Precision 490 with two dual core CPUs. It has 16G Ram, an 150G Intel solid state drive, a 230G data drive, and a 600G backup drive. I have two Samsung monitors attached to the NVIDIA Geforce FX 5xx card. I have been using this machine for several years with Etch, then Lenny, running KDE 3.5. I recently needed to upgrade to Squeeze and KDE4 and have had nothing but problems since. I keep having issues with the video drivers, every time I touch anything the drivers seem to upgrade from the legacy 173 to the current 195.
There have been other library compatibility issues as well (gclib) and the machine has not been stable. This morning the system was running very slowly with X running at 100% (from top) and then the entire system froze. After a hard reboot, X did restart. The Xorg.0.log has the following message:
"Failed to initialize the NVIDIA kernel module! Please ensure that there is a supported NVIDIA GPU in this system, and that the NVIDIA device files have been created properly..."

ive been trying to move myself away from windows, but it seems like ubuntu just wont have it, either that or win7 puts some curse on ubuntu Just done my 3rd(3rd time this error has now happened) fresh install of ubuntu 9.10 onto my second hard drive(first hard drive has win7), install seemed fine, boots up nicely into grub, got the internet working fine(worked out of the box, wireless), other programs run fine, all seems to be working wonderfully well!
Until I tried to update, started up the update manager, clicked on check, its finds loads of updates so I let it download them, downloads all 200+ updates, starts to install them.
The updates are installing fine but then about three quarters of the way along the progress bar for installing it gets an error.Heres the details it showed at the error: (the rest of the details just looked like successful installs/updates)

Trying to change permissions on a file in /proc/sys/fs/inotify. The command syntax are:
Code:

and the result is:
Code:

Parent directory permissions are dr-xr-xr-x, and are the same up the chain. Tried to change the directory permissions to u+w, that didn't work either. FWIW, /proc is part of the / partition, and it has ~600MB free space.
I am trying to read the /proc/net/tcp6 file of a huge server (chat server) for monitoring the tcp6 connection states.
My server's tcp6 file has more than 26000 lines. For monitoring the server connections, my monitoring tool has to read the /proc/net/tcp6 file quickly in a regular interval (5 secs) and process. Presently it takes minimum 6-7 seconds for reading the whole file.
My tool can able to read the normal file (26,000 lines) less than 1 second, but it is not possible to read the same size of proc file.
I have 2 questions:
1) Why proc file takes more read time than normal file?
2) Is there any way to read the /proc/net/tcp6 file more quickly?
I am using RedHat MRG on a standalone intel PC that has 8 cpus. It has 2 Quad cores. I am trying to force some specific persistent tuning on it so that the OS and IRQs are all on one CPU socket and then I can run my Application on the other CPU socket (4 CPUs) using the taskset command.
I have been reading up on this mainly at [url] and having some success. But, I have one IRQ that is not active until my application runs that I want to force it to be on CPU 4.
And so I believe I can do this by setting /proc/irq/default_smp_affinity to 10. But, I do not have such a file on my system. How can I create this file at boot time properly?
I am using Ubuntu-10.4 and postgresql-8.4.Now I have to change my SHMMAX variable for performance tuning.I have 16 GB.change it permanently and what is the suitable value for the DATABASE Server.
