[ceph-users] Question about PGMonitor::waiting_for_finished_proposal

Hi, everyone. Recently, I’m reading the source code of Monitor. I found that, in PGMonitor::preprare_pg_stats() method, a callback C_Stats is put into PGMonitor::waiting_for_finished_proposal. I wonder, if a previous PGMap incremental is in PAXOS's proposeaccept phase at the moment

Re: [ceph-users] Adding a new node to a small cluster (size = 2)

How full is the cluster before adding the third node? If it's over 65% I would recommend adding 2 new nodes instead of 1. The reason for that is that it if you lose one of the nodes, your cluster will try to backfill back onto the 2 nodes and be way too full. There is no rule or recommendation

[ceph-users] Adding a new node to a small cluster (size = 2)

Hi! A customer is running a small two node ceph cluster with 14 disks each. He has min_size 1 and size 2 and it is only used for backups. If we add a third member with 14 identical disks and remain size = 2, replicas should be distributed evenly, right? Or is an uneven count of hosts unadvisable

[ceph-users] ceph client capabilities for the rados gateway

Hello. The documentation which I found proposes to create the ceph client for a rados gateway with very global capabilities, namely "mon allow rwx, osd allow rwx". Are there any reasons for these very global capabilities (allowing this client to access and modify (even remove) all pools, all
