recently i install grizzly-2013.1 and make a new raw image of ubuntu-12.04 image, create an instance from this ubuntu-12.04 image, when i attach a volume to this instance, i can find the status of this volume has been changed to "in-use", but when i log into this vm and use "fdisk" to check the virtual disk, i can not find the attached volume disk, there is no error log in nova-compute.log and cinder-volume.log. when i reboot this vm, then execute "fdisk", i can find the attached volume disk. any one can tell me why this happenned. any tip will be appreciated

when you attached the volume and it doesn't seem to be working can you run the below on the instance

run the below while attaching:

watch 'dmesg | tail -50'

after the attach run the below:

cat /proc/partitions

ls /dev/vd*
