OK so this is a wishlist bug. Rebuild takes a list of files to inject: https://github.com/openstack/nova/blob/14.0.2/nova/compute/api.py#L2731
Evacuate doesn't: https://github.com/openstack/nova/blob/14.0.2/nova/compute/api.py#L3729 Since we don't store the injected files and evacuate is an admin operation, we can't get those back into the guest when it's rebuilt on another compute node. Rebuild is a user operation so they can rebuild with the same files to inject. We've been talking about getting rid of file injection for a long time so I'm not sure we're going to consider fixing this, but I'll bring it up in the dev ML since we always talk about dropping file injection but never seen to get serious about it. ** Changed in: nova Status: New => Confirmed ** Changed in: nova Importance: Undecided => Wishlist ** Changed in: nova Status: Confirmed => Opinion -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1638961 Title: evacuating an instance loses files specified via "--file" on the cli Status in OpenStack Compute (nova): Opinion Bug description: I booted up an instance as follows in my stable/mitaka devstack environment: $ echo "this is a test" > /tmp/my_user_data.txt $ echo "blah1" > /tmp/file1 $ echo "blah2" > /tmp/file2 $ nova boot --flavor m1.tiny --image cirros-0.3.4-x86_64-uec --config-drive true --user-data /tmp/my_user_data.txt --file /root/file1=/tmp/file1 --file /tmp/file2=/tmp/file2 testing This booted up an instance, and within the guest I ran the following: $ mkdir mnt $ mount /dev/sr0 mnt $ cat mnt/openstack/latest/user_data this is a test $ umount mnt $ cat /root/file1 blah1 $ cat /tmp/file2 blah2 Then I killed the compute node and ran "nova evacuate testing". The evacuated instance had a config drive at /dev/sr0, but it did not have the /root/file1 or /tmp/file2 files. This is arguably incorrect.
