Comment 5 for bug 1508482

For the Maintenance team regarding 7.0 MU

Steps to reproduce
1. Deploy MOS 7.0 environment (HA, 3 Controller nodes, without Ceph)
2. Create a 3Gb size file on a Controller node
dd if=/dev/urandom of=/root/test.img bs=128M count=24
3. Check free space on the "/" partition on Controller nodes. Run from the Fuel master node:
for i in `fuel node | grep "controller" | awk '{print $1}'`; do echo node-${i}; ssh node-${i} "df -h | grep /$"; done
For example:
node-5
/dev/mapper/os-root 15G 6.3G 7.7G 46% /
node-1
/dev/mapper/os-root 15G 7.4G 6.6G 53% /
node-2
/dev/mapper/os-root 15G 4.3G 9.7G 31% /
4. Upload the file to Swift
swift upload mycont /root/test.img

Expected result
Free space on the "/" partition on Controller nodes is not changed
for i in `fuel node | grep "controller" | awk '{print $1}'`; do echo node-${i}; ssh node-${i} "df -h | grep /$"; done
For example:
node-5
/dev/mapper/os-root 15G 6.3G 7.7G 46% /
node-1
/dev/mapper/os-root 15G 7.4G 6.6G 53% /
node-2
/dev/mapper/os-root 15G 4.3G 9.7G 31% /

Actual result
Free space on the "/" partition on Controller nodes is reduced
For example:
node-5
/dev/mapper/os-root 15G 9.3G 4.7G 67% /
node-1
/dev/mapper/os-root 15G 11G 3.6G 75% /
node-2
/dev/mapper/os-root 15G 7.3G 6.7G 53% /
