Re: [ceph-users] Very slow start of osds after reboot

Hi, I have RAID0 for each disks, unfortunately my raid doesn't support JBOD. Apart from this I also run separate cluster with Jewel 10.2.9 on RAID0 and there is no such problem(I just tested it). Moreover, a cluster that has this issue used to run Firefly with RAID0 and everything was fine.

[ceph-users] Very slow start of osds after reboot

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
