Hi, I haven't tried this before but I expect it to work, but I wanted to check before proceeding. I have a Ceph cluster which is running with manually formatted FileStore XFS disks, Jewel, sysvinit and Ubuntu 14.04. I would like to upgrade this system to Luminous, but since I have to re-install all servers and re-format all disks I'd like to move it to BlueStore at the same time.
You don't *have* to update the OS in order to update to Luminous, do you? Luminous is still supported on Ubuntu 14.04 AFAIK.
Though obviously I understand your desire to upgrade; I only ask because I am in the same position (Ubuntu 14.04, xfs, sysvinit), though happily with a smaller cluster. Personally I was planning to upgrade ours entirely to Luminous while still on Ubuntu 14.04, before later going through the same process of decommissioning one machine at a time to reinstall with CentOS 7 and Bluestore. I too don't see any reason the mixed Jewel/Luminous cluster wouldn't work, but still felt less comfortable with extending the upgrade duration.
