Currently my system runs on two disks, sda 30GB and sdc 1GB. sdb is my data disk. I have set the partitions as sda1 /boot, sda2 /(root) and sdc1 /(swap).
Thinking that sdc was udma33 i used the disk for a swap area. Later i found out that it is pio4 and i want to relocate my swap area to sda.
Using GParted Live i am planning to create a swap partition to sda. Will fixing the entry in fstab be enough to correct this or do i need to do something more?
I could also use some advice on which live debian image i can install in sdc, to use for rescuing purposes. The capacity of the disk is 1080MB.
As a side note, the images i find for usd-hdd are direct download. Are there any torrent files for these?
I have a brand new thinkpad X301 with 4GB of RAM and thinking of getting fedora 11 on it. The plan is to have it triple boot with vista/seven and hopefully OSx86. I am aware of the 4 primary partitions limit on an MBR disk. I was thinking of having a swap file instead of swap partition and not creating a boot partition as well. If I install the boot loader(GRUB?) on the root partition will I be able to boot it without any problems by using vista's boot loader?
Or Maybe I should install GRUB on the MBR and add all the other operating systems on it? Does anyone have any objections for not creating a swap partition or a boot partition? When comes to desktop environment I've been using KDE in the past, is there any major advantage of using Gnome over it? KDE seems to look really nice on fedora where Gnome is maybe more stable?
I am currently running Debian on a system with 3 scsi hard drives with Raid and have an identical back up server. I want to schedule a daily "mirror" copy of the server operating system and data so that if the primary server drops I can move the network plug to the next server and be back in business. Can someone let me know what would be the best solutions for this? I am new to linux so this may be an obvious question so if it is I applogize but I have been searching through the forums and have not found an adeqate solution.
I am having issues with Grub 2 after installing Debian 7.8.0.The computer is a HP Pavilion 500-307nb. I made the original harddrive /dev/sdb and inserted a Samsung Evo 840 as /dev/sda. From the original hard drive (/dev/sdb), I wiped the windows partition, but left all other partitions unchanged (in case I would ever want to recover the desktop to its original state). I replaced the wiped windows partition with a swap partition and an LVM partition.These are my hard drive partitions:
/dev/sda (Samsung Evo 840)
Number Start End Size File system Name Flags 1 1049kB 3146kB 2097kB primary bios_grub 2 3146kB 944MB 941MB ext4 boot 3 944MB 94.4GB 93.4GB host lvm 4 94.4GB 1000GB 906GB guests lvm
[code]....
The partition /dev/sda3 has 2 logical volumes with filesystem ext4 that I mount to / and /home.The partition /dev/sda2 is mounted to /boot..When I install like this, Debian installs fine, however Grub2 is not installed correctly.Debian installs grub-pc which seems not able to boot the gpt partition. So I boot the Debian CD in rescue mode and execute:
mount /dev/sda2 /boot aptitude purge grub-pc aptitude -y install grub-efi
After rebooting, I come in the grub rescue shell, which says: error: no such device: 986f2176--4a4b-4222-83b9-8636a034b3c7.
When I then enter in the grub rescue shell: set boot=(hd0,gpt2) set prefix=(hd0,gpt2)/grub insmod normal normal
Grub and Debian start up correctly.why can Grub not start up automatically correctly? Where does the UUID 986f2176--4a4b-4222-83b9-8636a034b3c7 come from? I have reinstalled Grub several times, I have reinstall Debian several times, I have even wiped all partitions from /dev/sda and recreated a new gpt table with parted and manually set the partitions in parted. Still on each reinstallation, Grub fails because it cannot find exactly the same UUID. Since this UUID is always the same, it must be stored somewhere, but it cannot be the partitions, I have wiped them and the partition table several times.
I did though a firmware update of the Samsung Evo 840 before reinstallation, could this be a cause?Also the problem is not in grub.cfg. Grub starts correctly if I enter the commands above in the grub rescue screen and the UUID value does not appear there.
During the second OS (CentOS) setup, the shared SWAP partition was formatted and now I get the following under Debian: Code: # free total used free shared buffers cached Mem: 507524 251436 256088 0 11488 78332 -/+ buffers/cache: 161616 345908 Swap: 0 0 0 How to configure Squeeze to use again this SWAP partition?
After some years using OS X, I'm returning on Debian on my Macbook Pro in single boot.
I've bought a Samsung SSD (850 EVO 500Go) in order to replace the slow built-in HDD.
But I've earned about the need of repartition of writing operation on that kind of drives, and I'm concerned about swap partition.
I need swap (especially for Darktable, browsers and maybe Steam games), but I wonder if the usual swap partition (even with discard mount option) is really recommandable for SSD drives.
Actually, on Debian wiki and others, the usual recommandation is "if you have enough RAM, don't use swap or minimise swapiness to 1", but using of swap file is not mentioned.
Indeed, if I have only one "big" partition on the SSD drive and TRIM activated, the garbage collector (low level) built in chipet's SSD will optimize SSD life, but I don't know how the low level garbage collection works with multiple partition.
So there is my questions :
- Will SSD garbage collection will preserve the disc use even if I have a 2GB swap partition ? - Will I'd use a swap file instead of swap partition (I don't really need to hibernate) ?

I had /var/log/messages open in tail on another terminal, but no message appeared. I tried the same command deleting one by one the parameters, but I got the same behaviour, so I don't think it is a parameter problem.
One of my disks in my computer crashed, it was the one containing /boot and some data partitions. The other system and /home partitions were on a second disk, which is ok.
I was wondering, can I create a new /boot partition, and keep on using the rest of the system? Can I somehow do it with a chroot from a live/installer disk, run grub, and use my system again? I have another disk which I can put in the system, but there is even an unused partition on the disk which is ok (but it is rather big for /boot).
I was trying to install Debian 5.04 on a Mac G4, and in typical geek tradition, I didn't RTFM. During installation, I nuked all existing partitions, creating new to my liking. But as I learned later during the installation process, yaboot needed a NewWorld partition, so I can't boot the installation. I don't have any OSX CDs with me (this is a used G4 I purchased of craigslist) with which to create a HFS partition.I've re-run the Debian installer, which lets me create a partition that is supposed to be of type 'NewWorld', but the installer does not seem to like it or recognizes it.
i had to install oracle in my laptop...it required a certain amount of swap space which i didnt have... i tried to create it using the datadump command... dd if=/dev/zero of=/extraswapf bs=1M count=512 i then rebooted and made the swapfile using: mkswap /extraswap i then made the entry in /etc/fstab as follows "/extraswap swap swap default 0 0" and i used the command : swapon /extraswap the swap space was visible after that... but after rebooting the swap space is not visibille
I had just installed gparted , not used yet.I have a problem , at the time of installation i havent created necessary swap space , my linux partition contains 30GB with ext2 filesystem..I'm fully having this , but my question is with the above mentioned tool can I recreate swap space from this 30GB , like 20GB as user space and rest 10 as swap space . Can I?
I wanted to delete the Snow Leopard partition and format the Swap Disk partition to something else. exFat was causing major file size bloat on small files. QT sdk bloated to like 11 gigs or something ridiculous like that. Anyways, I loaded up an Ubuntu 10.04 LTS live cd and gparted then deleted the Snow Leopard partition. Gparted said "Mission Accomplished" and tried to rescan the drive, but never found it. At this point I restarted the computer, a dell laptop, which didn't boot with an unable to find a bootable device error. The ubuntu live cd doesn't see the drive anymore. gparted scans for drives indefinitely and fdisk -l has no output.
I was reading another thread about someone with a bad partition table and I decided to join this forum. I'm not going to take any drastic actions with the partition (/dev/sda3) in question. I am going to wait for instructions on what to do first. I am not very good with Linux and need some hand holding. System: DELL 4550 Dual-Booted with XP and Ubuntu. Works OK, just no swap. Well, here's what I did: I deleted a partition for Windows XP Pro because it was a trial, and it ran out. I then decided to slide the swap partition for the Ubuntu Linux that I dual-boot into over. (If this was successful, I was going to try expanding the root partition to take up the unused space.) I used Gparted on a CD to do this, as I figured it was safe to do.
I now cannot mount the swap space at bootup (and have to go into a backup version of the OS), although I can use Gparted in Linux to execute the "swapon" command, and it appears that it worked because I now see "swapoff" as an option on the context menu. (I actually don't even need a swap partition, except to hibernate.) If I highlight the swap partition and click on "Drive" on Gparted's menu bar and select "Create Partition Table", it will erase all data on /dev/sda, so how do I fix the bad partition table non-destructively?
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 want to change the swap partition to another partition. Is there a gui that can make this process easier so I don't have to do things like manually editing files?
I've recently just installed ubuntu 11.04 but seem to have made a big mistake. During the install process I was asked to specify a location to be used for swap. Not really understanding what this meant I chose another partition on my drive with some free space but also a lot of my data. Needless to say I now cant see that partition. Is there anyway for me to access it? or to at least recover the information I need from there? its about a 200gig partition, and it used to be ntfs.
My motherboard supports up to 8GB DDR2. I currently have 4GB installed. If I maxed out my RAM, and installed 10.10 without a swap partition, I've heard this would increase speeds significantly. Would it? This particular rig runs multiple servers including an Asterisk PBX with FreePBX, XBMC, and Boxee. XBMC and Boxee do not run at the same time, only one at a time. Would it be safe to run with 8GB ram, and no swap partition? Running FreePBX/asterisk, XBMC, playing videos or ....., and every other background processes, free shows on average 50% free. Opinions?
I am getting a new SSD for my laptop and I have been researching the different tweaks for an SSD. I still have a question regarding the swap partition: is it better to not have one for an SSD? (I have 4GB of RAM...)
If I don't, how would I specify it during the installation process for 10.04?
I have a small disk and I want to resize to 2 gb the swap partition, how I can do?

I have the swap partition configured normally in fstab but it doesn't automount when I boot up. Not only that but I can't manually mount it either (ie with 'swapon -a', 'swapon -L /dev/sda7' etc). When I try I get this error -
I want to remove my swap partition. Probably one I would have to boot into a rescue cd and remove it, but aside from that is there any other consideration or commands that I need to be aware of?
I recently installed Ubuntu Server, the 8.04LTS release, on my dad's computer which, for the time being, has to dual-act as both a server and a desktop. Will be running solely as a server pretty soon, though. Anyway - since I was down on the budget and the project I put up the server for is still in a development phase and not worth to invest serious money in (at this stage), it has to run on a computer with the following hardware configuration (I left out the non-important parts):
It has 80 or so GBs of disk space, so I went for the low-mem, high-disk scenario and created a swap partition of 1,5 GB. However, I can notice that is rarely even used! I have set the vm.swappiness parameter to 95 but my swap partition is still not being used, even when the memory usage goes up to 90%. I saw it being used once, but only when the needed memory size exceeded 500.
Does anybody know how to force Ubuntu Server to use the swap partition?
I read an article earlier that suggested the swap partition is encrypted by default if you select an encrypted /home folder during installation, is that true (for Lucid)? I am suspecting it isn't because my hibernation works, which I believe shouldn't be the case?
How do fix my Swap Partition? Last night I added unused space to the main Ubuntu partition. Now I noticed the Swap Partition is always at 0 bytes. I'm using a Sony Laptop, and have enclosed two screenshots. One of the Disk Utility and a system monitor.
