I installed the Centos 5.5 on a WM instance. Run out of space after doing the updates. It is very difficult to keep re-partitioning /

How can I use the good old installation options etc?
What happened to control? This became a control nightmare.
I am running Nagios on CentOS. Everything is working fine, all my clients status is ok. One thing which is confusing me is "Root Partition WARNING" on my own server which has Nagios installed. I think that these things are controlled by nrpe, which is installed in clients servers. what i want to know is how i manage my own server, in which config files i have to make changes?

View 1 Replies View RelatedWith the release of CentOS 5.5 ext4 is considered stable in this distribution so I decided to migrate to it. Luckily I started from migrating fresh server with CentOS 5.5 using some instruction I found on the internet. I think I shouldn�t say, that I screwed the whole thing up ;) After about 6 hours cursing, kicking, and crying I solved the task and figured the correct sequence of actions. The small problem with migrating root partition is that you can�t unmount it BTW.
During migration task, I found, that CentOS 5.5 rescue mode is somewhat broken a little in terms of ext4 support. It can mount ext4 partitions successfully. But its e2fsprogs package (tune2fs, e2fsck etc.) doesnt see ext4 partitions and say, that superblock is corrupted on a partition once is converted to ext4 (at least it did it for me. May be I should force filesystem type with -t ext4 switch?). Keep in mind, that if you screw your system up too badly, you will not be able to run tune2fs and e2fsck on it from rescue modeBut you will still able to mount it if it is not corrupted badly. In all below examples,Boot your system normally and login as root. Upgrade kernel if you wish (I usually use yum upgrade to upgrade all on new machines). Then upgrade/install some other packages

I have just configure RAID 1 on my IBM X3400 Server in CENTOS 5 ..Partition information is md0 boot , md1 swap and md2 is root ....but after resyn when i run cat /proc/mdstat I realize that md0 and md1 is ok and present with [UU] status. BUT the md2 is showing on one [U_].. that means my root partition is not properly in RAID 1.. how can i make it active in both drive. Or i need to reinstall complete system again.

I was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?

How do I resize my linux root partition? I don't want to try erasing my linux partition, cos I will start everything over and I just don't have that enough time. And I know it will erase the boot loader, then I have to recover the MBR that is still looking so risky for me.
3 partitions (in order): Windows 7, CentOS and shared data partition.
I need to increase the size of the Windows 7 partition (c:windowswinsxs seems to be something not easily remedied).
GParted didn't work in moving things around (bad sector) so I wiped out its partition (# 2 out of 3) and I was able to increase the size of the Windows 7 partition (I can reinstall CentOS easily and not much work lost).
Except ... no more grub menu (unsurprising). This incantation does allow me to boot into Windows 7.
Is there any way of rebuilding the grub menu short of reinstalling CentOS (5.5)?

View 5 Replies View RelatedRecently I tried to install Fedora 12 x86_64 to my laptop. I ran the live fedora image from my cooldisk and then pressed "Install to Hard Drive" from live desktop. Then I went forward until I reached the partitioning section. Though I had ~28GB free space in my Harddrive, but it says: "Could not allocate requested partitions: not enough free space on disks."

I captured these steps by using Fedora 12 Live printscreen tool. I tried to install Fedora12 from its non-bootable DVD too, but no difference! So there's only 2 situations:
1. I did something wrong -> install Fedora and use its partitioning tool.
2. There's a bug in Fedora -> confirm that this is a bug and say me an alternative way to install fedora.
I would like to dual boot Ubuntu and Windows 7. I have Ubuntu 9.10 Live CD and Windows 7 Pro Live CD. Ubuntu is installed but Windows 7 isn`t. I have gparted installed. I found the following directions within Ubuntu documentation.
Master Boot Record backup and re-replacement
Back-up the existing MBR, install Windows, replace your backup overwriting the Windows boot code:
Create an NTFS partition for windows (using fdisk, GPartEd or whatever tool you are familiar with)
Backup the MBR e.g. dd if=/dev/sda of=/mbr.bin bs=446 count=1
Install windows
Boot into a LiveCD
Mount your root partition in the LiveCD
Restore the MBR e.g. dd if=/media/sda/mbr.bin of=/dev/sda bs=446 count=1
Restart and Ubuntu will boot
Setup grub to boot windows
I don't want to backup the MBR and restore as listed. I would rather use the Ubuntu Live CD to reinstall the GRUB.
How do I overwrite the MBR?
Do I use gparted and change the partition?
Do I create an NTFS partition as listed above?
Or what do I need to otherwise do to boot the Windows 7 Live CD so that it will install?

I am having trouble logging into my ubuntu 11.04 desktop. When I type my username and password to login my screen goes blue, as if it is going to next show my desktop wallpaper, but then it loops back to the login screen. I had no idea why and so I went to ALT-F1 and typed in "df" and it turns out that my root partition is full. This is strange since I set aside 40GB for it and I didn't install anything or that many programs that would fill it up. Anyhow, is this fixable by booting to a live cd and using gparted to make root bigger or is there a better way to fix this?

View 2 Replies View RelatedAs recommended, I'm creating a new thread for my configuring GRUB problems commented first hereWe are setting up a new version of a custom system, we are migrating to Ubuntu Karmic from another distribution (Slackware). Besides small differences between these systems (most of them from the most recent versions of software used by the latest Ubuntu, such as GRUB 2), it has been decided that the new system will run an union root partition using aufs and tempfs, basically, we are following the steps provided heree install the system to a new hard drive from an already running Ubuntu Karmic system, usingdebootstrap/chroot, we move the disk to another sytem, so we have to correct disk references, we are able to run this system and it behaves correctly the first time it boots, it bypasses the GRUB menu since there are no other systems detected. However, after halting the system and booting it, the GRUB menu appears with a new "recovery" option, we've managed to remove this recovery option usingGRUB_DISABLE_LINUX_RECOVERY=trueBut then, the GRUB menu appears again, this time with only one option to boot: our system installation. But when this GRUB menu appears, it has no default timeout and so it stays forever unless ENTER is pressed to boot into the selected entry.
The main problem is that we are unable to configure GRUB inside the new installation because it always returns this message:grub-probe error cannot find a device for /If we boot the system "normally" (mounting root to a normal partition), we are able to configure GRUB properly, but it does not behave the same when using the union file system as /We are only looking for a way to bypass the GRUB menu and boot our system, do you have any advice on how to properly configure the GRUB menu for our system

Say I need to do: find / -name somefile.txt
And say root partition / is mounted on /dev/sda5; however, let's say I also have 250GB partitions (/dev/sda6, /dev/sda7) mounted in /media - AND another location that I cannot currently remember. Say, also, that I know the file I'm looking for is on /dev/sda5.
Obviously, the above command will also descend in /media and that other directory which represent the big partitions, wasting time in looking for the file in the wrong place.
Is there a way to instruct find (or other command) to search only / on /dev/sda5, and NOT to descend to directories if they are on different partitions ?

View 15 Replies View RelatedThe RAID level 1 interested me because of its redundancy in both drives. And I successfully made it in a couple of partitions. But, I always did it after Linux installation. Then, I create both partitions, use 'mdadm' to create raidtab and RAID device (md0, for example) and then I format the RAID device with 'mkfs' and mount it.
Until there, it's all OK.
But my problem is to mirror ALL the hard disk, inclusive root partition. To do that, I guess I need no Linux installation, then create the RAID (md0, raidtab, etc) and after that install Linux in RAID device created.
But I'm new in Linux world and I have no idea how to do that.
