Rook <= 0.7.0 mon hostNetwork: true node IP issue

NOTE If you need assistance with steps 3 through 5, let us know on the Rook Slack and we are happy to help you.

WARNING You should not have to go through this section when having hostNetwork: false (or haven't even set it)! WARNING If you have/had multiple Filesystems created, this guide may not work for you because of a bug in Ceph that causes the mons to crash during the "FS Map" assertion.

1. Scale rook-operator down (e.g. replicas: 0).
2. Edit all rook-ceph-mon ReplicaSets to have command: ['sleep', '3600'] in the mon container, but copy the other args and command values somewhere safe for each mon.
3. Exec into the first mon and run: monmap --print /var/lib/rook/rook-ceph-mon-$MON_ID/monmap.

• Where MON_ID is the ID of the mon you execed into.
