Open Stack

Hello there,

I could not believe my eyes today.
We are talking about Cinder in Juno.
So we have a use case where we have to be sure we do snapshots
everyday, so we have a script that tries to do the snapshot in this
way:

while [ `/usr/bin/cinder snapshot-list | grep $DISPLAY_NAME | wc -l` -eq 0 ]; do
    /usr/bin/cinder snapshot-create --force True --display-name
$DISPLAY_NAME $VOLUME_ID >> $LOG_FILE 2>&1
    sleep 5
done

Looking over the log file we noticed that every snapshot required 3 or
4 tries to go through. Digging into the logs I found that I have some
snapshots that are valid, but they do not appear in the snapshot-list.

This is what I mean:

$ cinder snapshot-list | grep d0a750fd-37dd-43ee-87d8-aacbcacc5dc4
$ cinder snapshot-show d0a750fd-37dd-43ee-87d8-aacbcacc5dc4

Very same thing with the latest openstack client

macsp:~ proto$ openstack snapshot list | grep
d0a750fd-37dd-43ee-87d8-aacbcacc5dc4
macsp:~ proto$ openstack snapshot show d0a750fd-37dd-43ee-87d8-aacbcacc5dc4

I checked the entry in the mysql database for this snapshots, they
look exactly identical to other entries where the snapshot appear.

Is this a old Juno bug ?

thank you
