Which "reboot" do you mean: 1. run "reboot" command in Linux instance. 2. OpenStack software reboot operation 3. OpenStack hard reboot operation
Also, check instance's libvirt domain xml (use "nova show" to get instace's nova-compute host and "virsh dumpxml <domain_name>" to see domain's configuration), see if it has been changed after reboot. 2014-02-26 15:34 GMT+08:00 葛劲松 <[email protected]>: > > i hava same problem and i have another problem, when a reboot VM （ubuntu）, > the bind between volume and device number chengged。 > > > 1、create 6 volume ,size: 1、2、3、4、5、6 （G） > 2、use "nova volume-attach" respectively attach to a vm(ubuntu 12.04) > 3、inner VM use "fdisk -l " i can see /dev/cdb、c、d、e、f、g with size :1 > 、2、3、4、5、6 > 4、detach the volume with the size : 2、4、6 > inner VM use "fdisk -l " i can see that : > > before reboot after reboot > /dev/vdb 1 /dev/vdb 1 > /dev/vdd 3 /dev/vdc 3 > /dev/vdf 5 /dev/vdd 5 > 5、then i detached volume with the size 1. create a new volume with the > size 7,and then attach to VM. i can see that: > before reboot after reboot > /dev/vdb 7 /dev/vdb 3 > /dev/vdd 3 /dev/vdc 5 > /dev/vdf 5 /dev/vdd 7 > How should I do to Repair it. > Thanks for help! > > > 2014-02-26 14:34 GMT+08:00 Zuo Changqian <[email protected]>: > >> Hi >> >> Currently we use Cpeh RBD as cinder volume.
