Hi,
For a last 3 weeks I have been running latest LTS Luminous Ceph release
on CentOS7. It started with 4th RC and now I have Stable Release.
Cluster runs fine, however I noticed that if I do a reboot of one the
nodes, it takes a really long time for cluster to be in ok status.
Osds are starting up, but not as soon as the server is up. They are up
one by one during a period of 5 minutes. I checked the logs and all osds
have following errors.

As you can see the xfs volume(the part with meta-data) is not mounted
yet. My question here, what mounts it and why it takes so long ? Maybe
there is a setting that randomizes the start up process of osds running
on the same node?
Kind regards,
Piotr Dzionek
