I tried to create some swap files in /dev directory for my desktop. the dd and mkswap were ok. but when I try to swapon it, i get this: # swapon /dev/myswap swapon: /dev/myswap: Invalid argument but when I mv the file to some other directory like /mnt or /, the swapon works. could sb. tell me why? -- Tang Jianwei

Hello It is my first question here and I would like to thanks all of you to keep alive this stream and to give answers (I regulary read). Thanks for the good job. After installing CENTOS4.2 and "play with" I type the command swapon -s to verify everythings is ok but the command does nor return info as it should do. Is it something known ?

Hey Listee's I have a CentOS server with 2GB of ram and a swap drive of 4GB; swapon -a shows my swap drive as 4GB with only about 350 bytes in use (which is fine as my server idles with about 350-400MB ram usage so no swap should be in use. However my one and only swap drive had a priority of -1. I had read that the swap drive priority doesn't matter too much because I only ha...

...om ramfs to tmpfs. Now I'd like to test this out better. Currently I'm only using initramfs to store data so I'm new the this klibc thing. Tommorrow I'm going to try to get klibc working to run some programs in early-userspace. From what I've read so far, i'll need a swapon utility that's compiled against klibc. Does klibc have the swapon syscall? If it doesn't how hard would it be for me to add it in? I want to turn on swapping and create a file larger than my physical ram and see what happens... :) John

...ded partitions. Under extented partions , there are 15 partions. Whole hard disk has been partitioned in a standard way, (i.e NOT LVM) It has 2GB ram. swap is also 2GB. Now I want to extend this swap to 4 GB. If I use dd coomand and create a file with 2GB, Will I be able to extend the swap witn swapon commnad? How can I achive this?

The swapon label test has a side-effect, in that it creates a new partition. This causes the later failure of the list_partitions test. This change causes the swapon_label test to scrub /dev/sdb after the test, and then re-read the partition table. --- src/generator.ml | 4 +++- 1 files changed, 3 insert...

Hi. I want to make a snapshot from a logical volume and noticed that there must be enough free disk space in the volume group. Actually there is no free disk space left. How do i shrink online /var without losing any data or restore from backup? I do not have physical access to the server.

I just upgraded a blade server via rsync from another server. Rebuilt the initrd. It boots fine... except that it won't turn on the swap partition. Several times, I've made sure swap was off, then mkswap -L SWAP-sda3 /dev/sda3, but when I do swapon -L SWAP-sda3, it complains it can't find the device for the label. The only thing I find while googling, other than redoing what I've done several times now, is an old bug from CentOS 4, 0001399, which affected *only* blade enclosures: the reporter says that all of his IBM blades were affe...

...or something? I'm relatively new to this distribution stuff (been doing LFS in the past and many other *IX things before that). I did a search using "rpm illegal instruction" of the lists, but didn't see anything that seemed appropriate. By the way, if the rc.sysinit has the swapon moved up to the front, things work OK. If not, things freeze up as mem is exhausted. Swapon does not appear to be bothered by the fact that LVM is not in control yet. Even if it is, I added another disk, set up two swap areas there and sailed on. Performance counts on a (equiv. to) P75! 8-O I...

Hello, I'm in a slightly unusual situation and I'd really appreciate some advice. I installed CentOS 5.2 on a server about a month ago. Today I happened to check the 'free' command and noticed that the Swap line reads as follows: Swap: 0 0 0 I'm pretty certain that when I installed the OS and created a custom partition table, that I defined a
