Hello, I am confused by a warning from mkswap : When making a swap on a LVM volume, I see the following warning : mkswap: /dev/vg_SDB1/swap_test6_64: warning: don't erase bootbits sectors on whole disk. Use -f to force. Setting up swapspace version 1, size = 1048572 KiB Is it safe to use mkswap -f in this case ? (If that matters, the swap is intended for a virtual machine, and the

Howdy, I have renamed a directory on NFS ver 3 server and then created a new directory again with the same name. # mv dir dir-hosed # mkdir dir The directory is auto-mounted on client side. I had unmounted directories on client side before making above changes. Now when I try to mount back 'dir', I still see old files and not new empty dir. Am I missing something here in the NFS config?

Hi, I need to mount a LVM in rescue mode to create a new initrd image. I am not sure how do I fond out which LogVol is to be mounted. How do I find it out? In most of the configs I have used LogVol00 with ext3 filesystem which contains OS install. This particular system is not installed by me and I am not sure how do I find it out. I did try 'lvm lvs' command, but probably that's not

I am trying to mount a logical volume for creating new initrd image. The lvs command is showing a logical volume with 'd' attribute - device present without tables. It's getting listed under /dev/mapper but not under /dev/VolGroup00. Any help on what might be wrong here? -- thanks, neuby.r

How do I pass xargs input one line at a time to subsequent command? For example I want to install rubygems by reading a text file as shown below, however the arguments are getting passed all at once to the 'gem install' command. I hace tried -L (max-lines) and -n (max args) options, but it didn't work. What's missing here?? Any help? $ cat gem.list.1 mkrf rake xmlparser $ awk

Avoid passing an empty UUID string to mkswap, which mkswap does not accept (correctly) as new UUID.

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

hi, am starting to play with XEN - the virtualisation project (http://xen.sf.net). i''ll give some background first of all and then the question - at the bottom - will make sense [when posting to lkml i often get questions asked that are answered by the background material i also provide... *sigh*] each virtual machine requires (typically) its own physical ram (a chunk of the

I am using an 8G CF card. (I was using dd to duplicate the card with different size cards I was advised not to). So I wrote the script below which basically: 1) runs fdisk to setup the device 2) makes the ext3 file system and the swap 3) mounts my old image "/" filesystem and the new partition 4) tar and untar the directories 5) run grub on it 6) set label for "/" After I

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

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 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

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

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
