Has anyone experienced a swap failing to be mounted in domU''s? I created a LVM swap space, ran mkswap and made it available on the same line as the root partition (also on LVM) in each of the domU''s config file. But it fails to be mounted and I''m running without swap space. That wouldn''t be too much of a problem if I had a lot of mem to play with but

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

Hi All, I could not locate the info & syntax to setup swap partition in domU. I''ve setup the fstab file like that after having created a LV for it but I don''t know how to instruct xen to use it:. I feel I have to somehow set it in the VM file but how ? Of course I''ve run the mkswap and tried swapon -a but I get the obvious message bellow as it cannot read real

Avoid passing an empty UUID string to mkswap, which mkswap does not accept (correctly) as new UUID. In addition, print a warning when the UUID of a swap partition changed, since it may require manual fixups in the guest. --- resize/resize.ml | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) diff --git a/resize/resize.ml b/resize/resize.ml index fbb2d021b..48c75161d 100644

(depends on Advance Storage Configuration patch) This patch adds the option of requesting, at install time, that swap LVs be encrypted.

This lays the groundwork for setting Root and RootBackup onto individual partitions for multiple disk installations in the future.

I just add a partition /dev/sdb3 and use "mkswap /dev/sdb3" to make it swap space. How can I label the /dev/sdb3 like "SWAP-sdb3"? what I want is put on /etc/fstab as entry like: LABEL=SWAP-sdb2 swap swap defaults 0 0 LABEL=SWAP-sdb3 swap swap defaults 0 0 Thanks

I am running Xen 3.0.1 with Gentoo for Dom0 and when I create a DomU with Debian, the kernel or system does not seem to recognize the volume I have created for swap on the DomU and will not mount it during boot or after. here is the disk section of the xen config for the DomU: disk = [ ''phy:xen-disks/disk-root,hda1,w'',''phy:xen-disks/disk-swap,hda2,w'' ]

Hi guys. DomU config disk = [ ''phy:/dev/xen00/debian5-base,sda1,w'', ''phy:/dev/xen00/debian5-swap,sda2,w'', ] ----------------------- mkswap /dev/xen00/debian5-swap But in domU in booting: Activating swap...failed. What wrong? -- Best Regards, alex.faq8@gmail.com

I have resolved my mysql problem it had to do with an improperly configured host file. My most pressing problem is why mounting swap fails in all my domU''s. My disks are LVM based. /dev/xen/www_swap for example it the (duh!) swap space for the www domain and exported from the xen file as disk = [ ''phy:xen/www,sda1,w'' , ''phy:xen/www_swap,sda2,w'' ] I

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 have one swap

I just recently posted a patch to the linux-kernel mailing list to move rootfs/initramfs from 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
