View 1 Replies View Relatedwhy the operating system is not using swap.I am using Fedora Core 13, it did have 4GB of ram, all of the ram was used. performance was poor. I used free and top to check if it was swapping - according to both, swap was NOT used at all. Never the less, I upgraded to 8GB and performance improved a lot.However, once again, free and top state that ALL the ram is utilised, yet NONE of the swap is utilised.

Could you either point me to a backup tutorial or give me the quick overview of preserving stuff with Ubuntu?
(This is for a 100% Clean install)
Q1) I was wondering if it is possible to Dual boot Ubuntu with Windows XP on a 1TB RAID-0 setup ?
Q2) Also, is it possible to create a SWAP partition (for Ubuntu) on a NON RAID-0 HDD ?
Q3) Lastly... I read GRUB2 is the default boot manager... should I use that, or GRUB / Lio ?
I have a total of 3 HDDs on this system:
-- 2x 500GB WDD HDDs (non-advanced format) ... RAID-0 setup
-- 1x 320GB WDD HDD (non RAID setup)
(The non RAID HDD is intended to be a SWAP drive for both XP and Ubuntu = 2 partitions)
I plan on making multiple partitions... and reserve partition space for Ubuntu (of course).
I have the latest version of the LiveCD created already.
Q4) Do I need the Alternate CD for this setup?
I plan on installing XP before Ubuntu.
This is my 1st time dual booting XP with Ubuntu.
I'm using these as my resources:
- [url]
- [url]
Q5) Anything else I should be aware of (possible issues during install)?
Q6) Lastly... is there anything like the AHCI (advanced host controller interface) like in Windows for Ubuntu?
(Since I need a special floppy during Windows Install...) I want to be able to use the Advanced Queuing capabilities of my SATA drives in Ubuntu.
Can it be done? I finally got antiX running a 64MB base memory machine, bit I neglected to add a swap.

So my 1GB of ram is maxed out. Things are kind of slow but not crawling (though at times, simple things like scrolling are stalled)
But it reports Swap: 0% in use.
Seems confirmed by the following:
Code:
$ free -m

So my Ubuntu 9.10 install has been hanging on boot lately. At first I thought it was a problem with the 2.6.31-20 kernel, because that is the default boot option in GRUB2. It seemed things worked fine if I instead chose the 2.6.31-19 kernel, but I had that hang yesterday too.I also had 2.6.31-20 boot just fine yesterday. Once. Next time I tried it - system hang.
What I mean by "hang" is,I would see the GRUB OS selection screen (I have 2 versions of Windows and 2 versions of Ubuntu on this machine),select the first choice (Ubuntu with the 2.6.31-20 kernel),see the "pulsating white Ubuntu logo" briefly,then a bunch of scrolling text, then...blank screen.Then nothing.I let it sit for a few minutes to a few hours when it did this, but nothing further happened.Then yesterday, I decided to let it sit the whole time I was at work, approximately 9 hours.I came home to a screen with the white Ubuntu logo and the following error message:
Code:
One or more of the mounts listed in /etc/fstab cannot yet be mounted:
swap: waiting for UUID=3fba81a3-de14-4f56-9e7b-ace95d933a0e
/proc/bus/usb: waiting for none[code]....
So it looks like I have a disk partition that refuses to mount sometimes.Gparted for some reason wouldn't tell me the UUIDs of swap partitions.They also don't show up in /dev/disk/by-uuid. Using the bootinfo script, I found out that 3fba81a3-de14-4f56-9e7b-ace95d933a0e is the 4 GB swap partition associated with my Ubuntu 9.10 install.The disk that partition is on is rated "healthy" by Disk Utility, with only a few bad sectors. The HDD is about 7 years old, so it's in remarkably good shape.What could cause this swap partition to not mount during boot, and how do I fix it?
I am using Kubuntu Amd64 Lucid on my desktop and I have allocated 08.03 GB partition for swap. But today I have noticed that system monitor is showing this as 09.90GB which is incorrect.
I tried deactivating the swap from KDE Partition manager. Even after deactivating swap it still shows the swap as 1.9 GB. So there is clearly 1.9 GB swap added to my system. I am not sure how. Attached screen shot clearly shows the system monitor issue. One possibility is, I have 4 GB (3.7 asper system) RAM comprising two units of 2 GB cards. Is this 1.9 GB read from one of these? I tried to boot the system from Kubuntu AMD64 live CD and then it showed only 8 GB as expected. So not sure whats causing this issue in my installation.
I wonder whether to place swap partition on LVM or on standard fdisk partition which will not be in LVM.What is better and more often used on production ?

I looked around the forum to see if there was anything like what I had or if it was even possible but I didn't see anything quite like this.I was wondering if this was even possible, and if so, would anyone be able to tell me what filesystem I should use for my windows swap partition?

I'm installing the ubuntu on my new computer with 1 TB hard drive (and core i7 870 with 4G RAM), for the purpose of scientific computing. I have two questions:
1. Since I am not absolutely certain that the simulation won't use larger swap space than usual (say 3x4G = 12G), I intend to set it initially as 12G keeping in mind that I might have to extend it later. So one might suggest putting it on lvm partition. But then I read that I can maximize the speed if I put the swap at the outer track. If I mix it with the other logical volumes in the same volume group, then I don't know where my swap space is across my hard drive, isn't it? So this might suggest I make it as a primary partition. I'm stuck..
2. My current planned partition map is
/ 1G
/tmp 10G
/usr 20G
/var 5G
/home the rest
taking into account I will install MATLAB and maybe other visualization software. What do you think of this scheme?

View 1 Replies View RelatedAssume I have a computer on which I want to use ubuntu for a while (single boot). Assume also that in about six months I want to give this computer to Mr. X, but I do not want Mr. X to know that I have been using ubuntu. I don't want to install anything over top of ubuntu, I just want the computer to be completely (or as nearly completely as possible) blank so that Mr. X cannot infer what I've been doing on it. The trick here is that I can't use operating system x_{1} to delete operating system x_{0}. I don't want Mr. X to know anything about which OS I have been using. Mr. X, by the way, is a sophisticated computer user but not particularly interested in tracking me down. Once he sees that the computer is blank Mr. X will just install his own operating system and everybody will be happy.

View 1 Replies View RelatedI had to delete my swap partition in order to reinstall win XP, but now I need to reinstall it. I run Ubuntu 10.04 and read that there is a command $ sudo mkswap /dev/sda1. I have about 19 GB of free unpartitioned space left on the hardrive that I want to make into a swap partition. I'm not sure whether I should use sda1 or if the book uses it as an example and if I use it it could wipe away my existing partition with ubuntu installed on it.
