Open Stack

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 at 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 at 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 at 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?


Thanks
