IIRC Rydekull and I already have our keys there. Last time I used it,
there were some actions that need the password though (such as using the
RHC tool to easily restart).

It's easiest to just use www.ovirt.org, which is a CNAME to
wiki-ovirt.rhcloud.com. I'm sure the username is now in the usual place.

Not sure what you exactly mean. Physically? Which directory?
You should know openshift does a lot through environment variables. For
example, there's $OPENSHIFT_PHP_LOG_DIR which points to the apache logs,
$OPENSHIFT_DATA_DIR which points to the persistent data, such as our
mediawiki image uploads or $OPENSHIFT_MYSQL_DB_LOG_DIR for the mysql
logs. env is a very useful command on openshift.

Disk is limited by standard quotas:
[wiki-ovirt.rhcloud.com 847edb45aea84198838f915be6faa066]\> quota -s
Disk quotas for user 847edb45aea84198838f915be6faa066 (uid 3689):

It seems currently most space is used by our database (3.5G) and as you
might know, mysql innodb storage is never returned. Even if you purge
all tables, the ibdata file can't shrink. That doesn't have to be bad,
but something to be aware of.

On what kind of plan are we? If free, I think the support is mostly best
effort on #openshift and https://www.openshift.com/forums/openshift.
