Re: [ceph-users] monitor takes long time to join quorum: STATE_CONNECTING_WAIT_CONNECT_REPLY_AUTH got BADAUTHORIZER

In my case it was syncing, and was syncing slowly (hour or so?). You should see this in the log file. I wanted to report this, because my store.db is only 200MB, and I guess you want your monitors up and running quickly. I also noticed that when the 3rd monitor left the quorum, ceph -s

Re: [ceph-users] luminous vs jewel rbd performance

Hi Rafael, In the original email you mentioned 4M block size, seq read, but here it looks like you are doing 4k writes? Can you clarify? If you are doing 4k direct sequential writes with iodepth=1 and are also using librbd cache, please make sure that librbd is set to writeback mode in both

Re: [ceph-users] Bluestore OSD_DATA, WAL & DB

Some of this thread seems to contradict the documentation and confuses me. Is the statement below correct? "The BlueStore journal will always be placed on the fastest device available, so using a DB device will provide the same benefit that the WAL device would while also allowing additional
