Hi Wesley, You can also just run: $ ceph fs get MyFS|grep flags flags    32 joinable allow_snaps allow_multimds_snaps allow_standby_replay And if you can see "allow_standby_replay" flag as above that means it's enabled, or disabled already. - Xiubo On 21/10/2022 05:58, Wesley Dillingham

[ceph-users] Re: How to determine if a filesystem is allow_standby_replay = true

Hi Wesley, You can find if the `allow_standby_replay` is turned on or off by looking at the fs dump, run `ceph fs dump | grep allow_standby_replay` and if it is turned on you will find something like: $ ./bin/ceph fs dump | grep allow_standby_replay *** DEVELOPER MODE: setting PATH, PYTHONPATH

The ability to run as a stand-alone service without a RADOS service comes from the Zipper API work, which is part of upstream Ceph RGW, obviously. It should relatively soon be possible to load new Zipper store drivers (backends) at runtime, so there won't be a need to maintain a fork of Ceph RGW.

AFAIK radosgw uses the public network to talk to the OSDs. You could ditch the cluster network and have the public network use the high speed cluster network connections? Maybe there is another way, which I don't know. Cheers Boris > Am 20.10.2022 um 18:58 schrieb Wyll Ingersoll > : > >

What network does radosgw use when it reads/writes the objects to the cluster? We have a high-speed cluster_network and want the radosgw to write data over that instead of the slower public_network if possible, is it configurable? thanks! Wyllys Ingersoll

Hi Murilo, Is node-exporter running on that node? Most host page metrics are node-exporter's. As Marc suggested, you can also confirm it by checking whether there are "node_*" metrics for that node in the Prometheus web UI. Kind Regards, Ernesto On Thu, Oct 20, 2022 at 2:52 AM Murilo Morais
