I understand that a single linux swap partition could work as a swap partition for multiple distros, but could I use the same partition as a FreeBSD swap partition?
When I installed 12.04 Precise 64bit, I created a 16Gb swap partition. I know, I'm an idiot! After months of use, I never once saw the swap use more that about 300kb of hd space. Because of this, I shrunk the swap partition down to 4Gb. I didn't want to eliminate it altogether as I've read this can cause problems.
I upgraded my system to Ubuntu 14.04LTS, I encrypted the home & the swap partition during the installation since it was already encrypted in the old version.
But later I noticed swap partition is not used & using the gparted I found the swaps is damaged, I re-formatted the swap partition as Linux-swap & fixed the UUID in the fstab then cleared the crypttab, then swap was working fine
I have a Dell XPS Ultrabook with a Hybrid Drive/32G of SSD. I have installed my root partition and swap on the SSD and /home on my HDD. I have 8G of Ram and had allocated only 4G of swap on the SSD. Now I want to hibernate my laptop and need more swap.
I have 64gb RAM and 240gb SSD on my computer, which I'm going to use for memory-intensive calculations (machine learning/data mining/etc.)
Most of advice I found on the Internet are about 2-4-8gb ram computers, and they recommend 2x the size of ram swap partition (so 128gb).
The question is: is it reasonable to make 128gb swap partition?
Sometimes the swap partition will get a new uuid when you install a new distro. But that`s not the case here, because "blkid" should display the swap partition with the new uuid. As Ian says, you don`t have a swap partition with a uuid.Try this command: sudo fdisk -lThis command should reveal all the partitions, whether they have a uuid or not.
I created a 7.5Gb swap partition when I installed UBUNTU 12.04 on my 80 GB hard disk. My system runs with 512Mb RAM. I am not sure if this SWAP partition size is right. I also would like to know if the swap partition is being utilized by the operating system. Any suggestions?
I remember for choice of swap partition, we should use (swap > 2xRAM) at least.Of course it deprecated , because max of computer's ram is very high. kernel support it.
My question: i remember each partition of swap just support 2G maximum, it means if you have 2G ram you should create 2 partition of 2G swap. Did kernel solve it ? it mean can i create 4G swap for one partition?
