Hi,Is there a way to use the new upmap-read balancer mode when I have CephFS kernel clients connected? Our cluster runs Squid and all connected clients are on kernel 6.11-6.14, so they should be new enough. However, they identify themselves as luminous (I could not find clear documentation about this, but this seems to be hard-coded and by design), so I cannot run ceph osd set-require-min-compat-client reef, which is required for the balancer module to work.
I have 500 clients connected and migrating them all to FUSE would be a headache. Is there a way around that? Some of my pools have extremely high read balance scores and we're also struggling with performance issues as a result.
