View 3 RepliesI have a rack of four 1TB drives all partitioned identically with three primary partitions. On each drive
- the first partition is only 64MB;
- the second is a large 900GB partition and
- the last holds all the remaining space
mdadm has been used to set up
/dev/md0 - RAID1, comprised of /dev/sda1 and /dev/sdb1
/dev/md1 - RAID5, comprised of /dev/sda2, /dev/sdb2, /dev/sdc2, /dev/sdd2
/dev/md2 - RAID5, comprised of /dev/sda3, /dev/sdb3, /dev/sdc3, /dev/sdd3
OK, so it was a silly mistake to make - but I am now need to increase the size of /dev/md0. My thinking is to reduce the size of md1 so that I can grow md0.
On md1 I have two logical volumes. I've successfully reduced the size of the volume so that I can reduce the size of md1. Now I'm at the nervous stage; I can find little written on the topic of shrinking RAID5 arrays - and even if I do this I'm unsure if I can move partitions around to regain the space I so desire.
so i have f12 installed on my hd with lvm using the whole extent of the HD , i want to reduce it so i can dual boot it with a windows system, i managed to reduce the logical volume to free some space, but i cant seem to reduce the physical volume, is this possible and how ?

How can i reset the timeout to 3 seconds? I also cannot view the ubuntu partition within windows because of ubuntu's file system.
View 9 Replies View RelatedI want to set a limit on the available RAM in my Linux machine, it currently has 4GB of RAM, and in order to perform some experiments I need the system to recognize and use only 1GB. I don't want to limit the amount of memory to one particular process (like with ulimit), but to the whole system. The OS in Ubuntu 9.10. Somewhere a long time ago (for Fedora) I read about editing grub, so that at boot time the limit is set, it might be something along those lines, but not really sure.

View 3 Replies View RelatedI feel shy asking this question but, 90% of the applications I install in Ubuntu (last release), do not show up later on in the applications menu, so I cant run them. I know it seems silly, but I can't find the way to handle this inconvenience. Is there a place (like Start> All programs in Windows), were I could find and run all the programs I install?

1) Is there a better way to list the total count of all files in a partition and just display total number of files in each directory in that partition I can get approx total for the entire partition by following commands
ls -Rla | wc -l
find -type f | wc -l
whereas ls -Rla gives too lengthy outptut with all the files in each directory
2) How to know inode utilization for each user or system account? There is huge number of files and how to remove it

I resized a LV and freed up 10GB within the VG, but I want the 10GB outside the boundary of the VG so I can install another OS for testing purposes. For some reason I'm not able to do this. I don't know if I understand LVMs correctly. Maybe there can be only one VG on a HD?

I need to rip my DVDs, an operation which is heavy on the CPU, on my laptop. This makes the temperature rise very quickly, even if the process has very high nice value, and my laptop was already shut off automatically once. Probably there is some bug, since the temperature if often hotter than optimal, but this is really too much (plus these days my room is hot too).
I don't want to ruin anything, so I'd like to put some kind of limit on the CPU usage. Say I don't want any of the two CPUs to go over 70% (a moment ago they were both at 100%, I have paused the process). Is there a way ti d0 this?

I have an install of Mint 9, and the fan runs a lot less then it did in Vista, but it still is way to loud because it's not very warm at all. I was wondering if there is a tool for Ubuntu/Mint that you could adjust this issue. It would be nice if it was a gui tool, but anything will do, because it's really bugging me.

I was wondering if there was any way to remove icons from the installed applications menu?I recently attempted to install GOG.com's Zork Anthology using Wine and when I de-installed, the icons for those files were still listed in installed applications. Is there anyway to delete them manually?
View 2 Replies View RelatedI'm setting up a large number of virtual machines, each with a basic set of about 30 applications. Obviously, I don't want to do everything manually so I'm looking for ways to automate this process. Multiple distributions (Ubuntu, Red Hat Ent., FreeBSD, CentOS, etc.) will be used, meaning I will have a few Ubuntu installs with the basic set of 30 applications, and multiple Red Hat installs with the same set, etc. So, I'm looking for advice on automating as much of this as I can, even if it means a new form of automation for each distro.

I have a multiboot system with Windows Seven and Debian Squeeze installed.
When i run Windows, the fans in my PC work silently, but when i run Debian they making extremely terrible noise (looks like they working at full capacity).
I have 4 fans in my chasis, 1 CPU, 1 GPU and 1 PSU, 7 total.
Question: Installation had me entering my password many times, seemed like for most everything I did during install & setting up the desktops. It was a little frustrating compared to what I was used to with Ubuntu. I know this frequency will reduce once settled in although Linux and "fiddling" go together so some will continue. When using Ubuntu I was able to set that up to bypass some password need, not all. I was hoping there are options for that with Debian but my efforts all day yesterday failed to find any. I am not looking to eliminate password use entirely and I don't expect it to be just like Ubuntu either, however...
My main areas of frequent password use that are new to me with Debian Squeeze are:
1)All partition mounting. Using Ubuntu I edited fstab using a tool called "Storage Device Manager" so that only myself, not "users", had full read-write access to all partitions at boot time. However, none of those fstab codes or any new ones that I tried seemed to work in Squeeze. Besides Squeeze, I have two ntfs and one ext3 partition to access. Example: my music files are on an ntfs partition and I have to enter a password to listen to music.
2)Opening a root nautilus folder. In Ubuntu I made a custom application launcher with "gksu nautilus" and that gives you a no-password one-click access. In Squeeze, I enter a password every time.
3)Reboot & Shutdown. This one surprised me. Every reboot or shutdown requires my password unless I logout first but that adds a step. It may have something to do with a second desktop I installed (kde), I'm not sure. I tried making a script linked to an application launcher that runs "init 0" but that asked for my password too.
I'd like to be able to do 1,2 & 3 above without password entry other than maybe at the main log-in.
About me: This is my first post here, and am trying to be courteous. I checked the DebWiki, Google & this forum for answers. I found a little about ntfs partitions and saved it to a file. My situation is a Debian beginner but using Ubuntu for 7 or 8 months. My technical skills are mid-range. I use Debian on a newer dell laptop with Intel chipset and Intel CPU, triple booting Windows 7, Ubuntu 10.10 and Debian-Sqeeze-di-rc1-amd64. I installed using DVD #1, and made a local repository with DVD 1&2 and added a second kde desktop. Gnome Debian is my favorite now, it runs very well and will probably replace Ubuntu as my primary OS. Everything works that I can tell, except the Software Sources GUI does not load but I go into the source.list file and edit it manually.

In GIMP there is no feature how to reduce file size for ex. 1mb to 20 Kb. How do I do this? Do you know any good program to do it?
