Hey all,
From time to time we are facing an issue when puting instance in rescue with the same image as the one the instance was booted.
E.G. I booted an instance using Debian 10, disk are: debian@testarnaud:~$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sr0 11:0 1 486K 0 rom vda 254:0 0 10G 0 disk └─vda1 254:1 0 10G 0 part / debian@testarnaud:~$ cat /etc/fstab # /etc/fstab: static file system information. UUID=5605171d-d590-46d5-85e2-60096b533a18 / ext4 errors=remount-ro 0 1 I rescued the instance: $ openstack server rescue --image bc73a901-6366-4a69-8ddc-00479b4d647f testarnaud Then, back in the instance: debian@testarnaud:~$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sr0 11:0 1 486K 0 rom vda 254:0 0 2G 0 disk └─vda1 254:1 0 2G 0 part vdb 254:16 0 10G 0 disk └─vdb1 254:17 0 10G 0 part / Instance booted on /dev/vdb1 instead of /dev/vda1 Is there anything we can configure on nova side to avoid this situation?
