Aug 4, 2010Currently and for the last half an hour System Monitor reports 31% in use by programs 68% in use by cache
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:

Ubuntu :: System Hangs On Boot Because Of Unmountable Swap Partition?
Apr 17, 2010So 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?
Ubuntu :: Incorrect Swap Partition Size In System Monitor?
Jun 13, 2010I 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.

Ubuntu :: Delete Snow Leopard Partition - Format Swap Disk Partition To Something Else
Feb 23, 2011I had a drive with a partition layout like so:
~50gig Windows 7 - NTFS
~100gig Ubuntu - EXT3
~100gig Snow Leopard - HFS+
~100gig Extended Partition
-- ~100gig Swap Disk - exFat
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.
Hardware :: Invalid Partition Table For Swap Partition That Moved With Gparted?
Feb 8, 2010I 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?
Debian Installation :: Wiped Windows Partition With Swap And LVM Partition
Jan 17, 2015I 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.

May 21, 2011I'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.

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.

Feb 14, 2011My 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?

View 3 Replies View RelatedUbuntu Servers :: The Swap Partition Is Not Being Used
Apr 19, 2010I 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):
Code:
Intel Celeron 2.2 Ghz
~500 MB of DDR 333MHz RAM
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?

View 9 Replies View RelatedUbuntu :: Add A Swap Partition To Lubuntu?
Jan 19, 2011I have a live/persistent installs of Lubuntu 10.04 on a USB-HDD. It's on a 320 GB portable drive. I've partitioned it so that 80 GB is for the Lubuntu live install and the remaining 240 GB is another partition dedicated to storing stuff. So this USB-HDD is doing double duty. The thing is, I was paying so much attention to making the persistent install work without making a mess of the boot loader (I did that in the past; twice!) that I had overlooked the fact my live install does not have a swap sartition on it. I just assumed (incorrectly) that the swap partition on would just be part and parcel of the installation. Can anyone tell me of a way to add a swap partition to each of my live installs? Without losing any data or anything like that. It's probably not doing any harm not having a swap partition, but I'm assuming that my live install would be that much more efficient with it.
View 7 Replies View RelatedUbuntu Servers :: Swap Partition Does Not Get Used
Feb 15, 2011After unsuccessfully trying to install Oracle Express I find that for some reason the swap partition on my server disk does not get used.
My setup: 10.10 server x64 on an intel server with two 500gb HDs in a mirror array
This is puzzling, because I definitely created a swap partition for this system and indeed if I look at /etc/fstab I actually have two swap partitions, one on /dev/mapper/[some long raid name]_ar05 and one on /dev/mapper/cryptswap1, but AFAIK this is normal with 10.10.
"swapon -a" fails with this message:
Code:
swapon: /dev/mapper/[raid name]_ar05: read swap header failed: Invalid argument
swapon: /dev/mapper/cryptswap1: stat failed: No such file or directory
there's always the option of using a file on the server's filesystem, but I want to see if this can be fixed. I only have remote access to server via SSH, which makes startup troubleshooting pretty impossible.
I have a local server at home also using 10.10 server 64-bit with an encrypted swap file running on a RAID array, but it does not have this problem.

View 9 Replies View RelatedUbuntu :: Cannot Find Swap Partition After Hibernation
Feb 23, 2010Since I tested with suspending/hibernating my laptop, the system seems to have lost the swap partition. That is to say: it cannot find it at boot anymore. Some message shows during boot like "waiting for device listed in fstab: swap" or something and then it continues toboot normally. When I start the systemmonitor it reports Swap usage 0 byte out of 0 byte.
I checked my devices with
Code:
blkid
in terminal and it lists one of the partitions with its UUID as TYPE="swap".
Then I opened fstab with
Code:
sudo mousepad /etc/fstab
and noticed the line for the swap partition was using a completely different UUID. After changing the UUID to the correct (new) one and reactivatin swap with
Code:
sudo swapon -a
in terminal, all was well again but...
How could the UUID suddenly have changed? Did that indeed have something to do with trying (and failing) Suspend and Hibernate ? If so, should I stay away from those features (that served me well under Windows) or is there something to be done about it?
Ubuntu Installation :: Using FAT32 Partition As Swap?
Apr 5, 2010I'm installing a new SSD this upcoming weekend. My thought was to go easy on it so it lasts longer by putting my swap files on a mechanical drive instead of the SSD. I don't - however - want to waste space for swap files. It would be nice if I could use the same 6GB FAT32 partition for swap files for both Windows 7 and Ubuntu. Is this possible? It might not even be necessary though, I have enough RAM that I rarely use the swap file at all (I've even considered going without swap all together), so it probably won't pose a huge load to the drive.
