My Centos disk was full. when I remove all the big files, df and du command not show right size. I reboot my server and in to rescue mode, it alert "you don't have any linux partitions".How do I fix it?I not use LVM.my server mount:
/dev/sda1 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
[code]....
give me the sequence for manually mounting devices in "rescue mode" ? When I try "linux rescue" from the install disk, it eventually fails to mount my partitions with a generalized failure message, which tells me nothing. I then try mounting them myself on /mnt/sysimage. I have separate root, boot, and home partititions. Is the sequence:
Mount root partition at /mnt/sysimage
chroot /mnt/sysimage
Mount boot partition at /boot
Mount home partition at /home
What about tmpfs, devpts, sysfs ? Do they need to be manually mounted also ? The 'mount' command does not show them as mounted after I do my chroot.
i have install a new qlogic hba card, but i dont know its model
View 1 Replies View RelatedI am working on a traffic surveillance project which performs various image processing tasks with a number of visual sensors and a computing platform. My basic task in the project is the power optimization/management. I am using a ZOTAC-IONITX computing platform (Intel ATOM CPU + NVIDIA ION GPU). The problems that I am currently facing are:
I am unable to model the power consumption of various components e.g., processor, GPU, hard drive, memory etc, since there seems to be no way to measure the power consumption of individual system components. Since I don't have a power consumption model, I cannot come up with a power optimization algorithm. I am currently working on Linux. Is there any way to measure/model the power consumption of individual system component?
I have already checked powertop. It doesn't tells the power (watts) consumed by a component (e.g., microprocessor). It just gives information about the power state the processor is in (However there is no way to change the power state by the user) and the processors that cause processor to wakeup.

I got my wife to try Linux, so we set her machine up to dual boot with Windows. After a few weeks, she decided not to use Linux, so we deleted the Linux partitions using Gparted on a USB drive and resized the NTFS partition, under the apparently mistaken impression that Grub would detect that there was now no other operating system. When we rebooted, we got error: no such partition, followed by a grub rescue prompt. I've never worked with Grub directly before, so I have no idea what to do at this point.

I installed ubuntu 10.04 into an external hardrive connected to my windows 7 pc as i wanted a dual boot. The installation went find and ubuntu installed into some free space on the drive. When it rebooted i got the grub rescue screen. I booted into the live CD and ran the boot script

View 1 Replies View RelatedI had Windows 7 and Ubuntu 10.1 installed in my intel i3 4gig DDR Sony Vaio E-series laptop. Both operating system were working fine. Only problem that I used to have was the sound didn't use to play when I boot through Ubuntu. Due to that, I formatted the corresponding drive from Windows in which there was Ubuntu installed. I used "diskmgmt.msc" to delete the partition and then format it. The format was successful and when I restarted my computer, this error was displayed:-
error: unknown filesystem
grub rescue >
Windows didn't load at all. I used to have multiple boot grub menu previously before formatting the partition but that didn't show up after formatting.I am unable to use any of the Operating System.
I am to reinstall the notebook of my father, that had Windows XP and Ubuntu on it. And I dont know anything on Ubuntu. My objective was to make a fresh install with XP only.So I was checking the partitions within Windows and found 7 or 8 of them which I could not understand: I asked to remove them, one by one, and got some error mesage on Windows. Now I understand these were probably used by Ubuntu.Now, when I restarted the PC,n I got:"error no such partition grub rescue"..I tried to boot from the CD - a windows XP setup CD, but I get blocked as well, because when I try formatting the drive during the installation CD it makes an error, or otherwise without formatting I also get an error.I guess the partitionning information of the hard drive is inconsistent, making everything fail.I dont know what to do.I am thinking to use a USB disk to reformat the HD, but I am not sure it will help.
View 5 Replies View RelatedI've got CentOS 6 installed and am wondering if it's necessary to have installation media in order to run 'linux rescue'. (I have to do some LVM resizing and would rather do it from rescue mode than in a running system.)
What I've read about booting into linux rescue is that it seems to be necessary to have installation media and boot into that. But I'm wondering if it's possible to do it some other way, like from the grub menu? But it doesn't seem to be possible to enter 'linux rescue' from the grub command line (which I got to by typing 'c' in grub menu screen) - typing 'linux rescue' at grub command line says 'command not found'.
Maybe there's another way to do this? Or some fancy way to have loaded a rescue image or something onto my disk so I don't need installation media. There's 2 reasons why I'd like to enter linux rescue without installation media, both because my computer is very old. 1) My computer can't boot from USB, and 2) My CD/DVD tray is very unstable and keeps popping out intermittently, so I'd need to hold the tray in place during the whole LVM process and it's a real pain, and I wouldn't want to risk data corruption if the process is interrupted by my CD/DVD tray popping out.
I'm hoping there's some way - it'd also be nice to know how to do this if some urgent situation arose where I needed to enter linux rescue mode but didn't have installation media handy and it'd take to long to retrieve or create new installation media.
So my 8 year old HP has finally bit the dust. Any opinions on a new HP model?

I can use a self-signed certificate, but the problem is most browsers makers are Fn idiots that say the connection is not secure, when it actually is, but because I did not folk out cash, it makes my website look bad. I can understand the need for a 3rd party to verify the domain host to prevent man in the middle attacks, but I do not care for this.. and browser makers should take more responsibility and introduce different padlocks for types of authentication, rather than saying "this connection is encrypted, but not secure because its self-signed". What a load of horse s***!
How many times does people stop to read certificate authoraties? I sure don't. I only care weather or not the connection has been encrypted.. so, I am looking for a way for simply providing encryption for my website.
From what I understand, when you submit a CSR to a CA, it includes the private key, meaning that the CA would be able to see the encrypt data, should they get hold of it. This is not acceptable for me.
Is there anything other way to use encryption other than the SSL model that is used typically amongst HTTPS browsers today?
