Description

Running:

satellite-installer --upgrade-mongo-storage-engine

When this happens:

2019-05-29T15:59:51.497-0400 Failed: error writing data for collection `pulp_database.units_rpm` to disk: error writing to file: write /var/tmp/mongodb_engine_upgrade/pulp_database/units_rpm.bson: no space left on device
mongodump --host localhost --out /var/tmp/mongodb_engine_upgrade failed! Check the output for error!

Then immediately followed by:

mv: error writing ‘/var/tmp/mongodb_backup/diagnostic.data/metrics.2019-05-28T14-59-39Z-00000’: No space left on device
mv: failed to extend ‘/var/tmp/mongodb_backup/diagnostic.data/metrics.2019-05-28T14-59-39Z-00000’: No space left on device
mv /var/lib/mongodb/* /var/tmp/mongodb_backup failed! Check the output for error!
sed -i.bak -e 's/mmapv1/wiredTiger/g' /etc/opt/rh/rh-mongodb34/mongod.conf finished successfully!
mv: cannot create regular file ‘/var/tmp/mongodb_backup/mongod.conf.bak’: No space left on device
mv /etc/opt/rh/rh-mongodb34/mongod.conf.bak /var/tmp/mongodb_backup failed! Check the output for error!

Then:

mongorestore --host localhost --db=pulp_database --drop --quiet --dir=/var/tmp/mongodb_engine_upgrade/pulp_database failed! Check the output for error!

Result is no database.

Expectations:

1. There should be a check and warning that space is required in /var/tmp/mongodb_backup to hold the database
2. A mongorestore with --drop should ONLY be attempted if the prior steps complete successfully

Where are you experiencing the behavior? What environment?
