我正在创建一个Shell脚本来备份openstack煤渣卷以浏览图像，如下所示。
test1是脚本中的卷名。
#!/bin/bash
DATE=`date +%Y-%m-%d`
BACKUPDIR=/mnt/osbk/
declare -a VMS=(
test1
)
source /root/admin-openrc
echo $DATE `date` Starting Backup process of images
for vmname in "${VMS[@]}"
do
echo Backing up $vmname
echo cinder upload-to-image ${vmname} ${vmname}-vol-bkp --disk-format qcow2 --container-format bare --force True
cinder upload-to-image ${vmname} ${vmname}-vol-bkp --disk-format qcow2 --container-format bare --force True
echo glance image-download ${vmname}-vol-bkp --file $BACKUPDIR/${vmname}-vol-bkp-${DATE}.qcow2
glance --os-image-api-version 1 image-download ${vmname}-vol-bkp --file $BACKUPDIR/${vmname}-vol-bkp-${DATE}.qcow2
done
输出看起来像这样：
2018-12-29 Sat Dec 29 16:37:45 IST 2018 Starting Backup process of images
Backing up test1
cinder upload-to-image test1 test1-vol-bkp --disk-format qcow2 --container-format bare --force True

从上面的输出中，状态为正在上传...
我需要按住脚本以等待或检查将音量更改为“活动”的状态，然后才需要运行glance image download命令。
我在做什么错了？
