Re: MON crashing when upgrading from Hammer to Luminous

[JC Lopez <jelopez@xxxxxxxxxx>]

Hi 

you’ll have to go from Hammer to Jewel then from Jewel to Luminous for a smooth upgrade.

- http://docs.ceph.com/docs/mimic/install/upgrading-ceph/#upgrade-procedures

- http://docs.ceph.com/docs/luminous/release-notes/#upgrading-from-pre-jewel-releases-like-hammer

Make sure to check any special upgrade requirement from the release notes.

- http://docs.ceph.com/docs/luminous/release-notes/#upgrade-from-jewel-or-kraken

Regards

JC
