<Audrius Blaževičius> well, but if you want to restrict the minimum version, the kernel clients block that
2024-10-17T05:55:09.266Z
<Audrius Blaževičius> for example if you want to use `read` balancer. all clients must be reef or newer
2024-10-17T05:55:54.159Z
<Audrius Blaževičius> same with `upmap-read`

<Audrius Blaževičius> this tells me to set min compat client to reef
2024-10-17T05:58:37.404Z
<Audrius Blaževičius> and I cant do that with "luminous" clients

<gregsfortytwo> that part of the system with client versions is maintained by the rados team, and the read balancer has had some bug fixes (I’m not sure that client version statement is correct after some of them), so you’ll have to ask them or go to <#C1HFU4JK1|> and see what others have done

<Andrea Bolzonella> Hi

<Andrea Bolzonella> How is possible that the "max_mds" is 0?
2024-10-17T07:04:03.161Z
<Andrea Bolzonella> It a pacific cluster
2024-10-17T12:28:35.221Z
<Patrick Donnelly> someone did `ceph fs set foo down true`
2024-10-17T13:41:23.896Z
<Andrea Bolzonella> ok thanks

<Christopher Hoffman> What is the criteria for selecting "Code cleanup (no ticket needed)" when submitting a PR? It seems there's more submissions with this lately. Do we have it documented anywhere?

<Patrick Donnelly> no, it's a "use your best judgement" type thing
