Hi Jonathan, On 12/6/10 5:24 PM, Jonathan Tripathy wrote: Hi Everyone,When providing Xen guests to cutomers, it is important to make sure that the LVM LV is "zeroed" before use. What is the correct syntax to do this?I've tried: dd if=/dev/zero of=/dev/vg0/lvnamehowever this seems to go on forever (unless my test machine is just slow!)Any ideas? That command will use a default block size of 512 bytes which takes, indeed, forever. Try: dd if=/dev/zero of=/dev/vg0/lvname bs=1M Regards, Thomas _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
